Found it. Since the gas goes through the same hose as the other blends, if you’re buying gas you need to get at least 4 gallons so the previous gas flushes out what was left in the hose from the previous sale, and fills enough of the container that the blend is primarily what you selected.
If you buy E15 and fill your tanks, then the next guy buys E10 and only gets 1 gallon, they might end up with a higher ethanol mix than intended, and if they use that on a small motor, like a chainsaw, it could ruin the seals.
I’m in Europe and I have never in my life seen a gas station that dispenses every fuel through just one hose.
Every fuel has its own hose and “pistol”. Each “pump” has two or three or four hoses.
In America, if a corner exists a company will cut it.
It feels like blending hoses would be a more complicated setup?
Multiple tanks hooked up to one valve and hose vs. multiple tanks with their own separate valves and hoses.
Obviously, it’s a different kind of valve in the first setup to prevent backflow into other lines, but that’s probably about the extent of it. With the second setup, you probably need to run a new line and pump for each station for each gas type, compared to just tying the tanks into the one valve and pump per station.
I’m not a plumber or anything, though, so take it with a grain of salt.
I feel like we should specific for Europeans or whomever that there is definitely a different hose for Diesel
In the US only diesel gets its own pump, at least in my experience
Same though I do recall seeing pumps with multiple hoses for each grade a lot more frequently back in the '90s and '00s.
Glad someone is thinking of the shareholders
In the US only diesel gets its own pump, at least in my experience
Yeah I always thought so too and then I ran into pumps like this in North Platte, Nebraska last June.
https://lemmy.today/pictrs/image/ab6bd220-9b30-47e6-aab6-dbc24ad683c3.jpeg
Edit: I couldn’t fuel up at that pump as my car requires 92+ Octane.
There are a few stations near me that have E85, “88 octane” (which is just 12% ethanol), diesel, and three grades of gasoline. Since you can’t mix those other fuels with gas the pump has four hoses and you still have to select the grade of gas.
Here’s a pretty typical american pump: https://www.alamy.com/stock-photo-shell-station-gas-pump-135764267.html You can select diesel with the green button, which comes out of the green handled hose on the left, but any other option for regular gas (87/89/93 in that picture) comes out of the right hose.
In America drastically different fuels like E85 and Diesel are dispensed with different hoses as mixing those with normal gasoline or vice versa in the wrong system could cause damage. But when it comes to different grades of just gasoline it’s all the same hose. E10 or E15 are pretty much standard in many parts of the Country of Corn (USA) so they are the primary form of gasoline available for normal cars.
(US) I’ve been to gas stations in big cities, small towns, little collections of buildings that have no official name but they have a dollar general and a gas station, etc…
I’ve seen several kinds.
Single hose to dispense 87-93 (“normal”) gasoline, and one for diesel
One hose for normal gas, one for diesel, and one for high-ethanol
One for all gasoline types and one for diesel
One super fancy stainless-steel-clad gas station that looked like something from retrofuturism had 5 hoses, one each for 87,90,93, e15, diesel, and the farthest end pump had a line for kerosine.
Never seen a combined gas and diesel hose though.
Every fuel has its own hose and “pistol”. Each “pump” has two or three or four hoses.
While those do exist in the States too, a single hose and “pistol” is used for all grades of gasoline and the operator presses a button to select their grade of fuel. The only time there is a guaranteed separate is between desil and gasoline:
The button leads to some interesting minor social problems. The expectation is that the use uses their hand or fingers to press the button, but the buttons are usually disgustingly dirty, so that lead many to using the tip of the “pistol” to smack the grade of gasoline which may put a drop or two of gasoline on the button. So those that come next and use their hands end up smelling like gasoline.
No longer interacting with public gas pumps is one minor joy of driving an EV.
i’m gonna be real with you buddy i have never seen a “disgustingly dirty” fuel button so I think the people in your area just grody. no offense to present company.
You never hit up a Shell station? Majority of them and independents I’ve been to have buttons that are worn through on the octane text for low grade. High octane is usually next most worn
I am a refined gentleman who only goes to turkey hill and wawa.
its a thing often in America, there’s just 1 hose and you press a button to select what blend you want.
Not in the us
Frequently in the US.
I’m in Australia and it’s on the pumps—like little manufacturer stamps that don’t seem to be aftermarket labels. Most people wouldn’t notice it and those that do wouldn’t understand what it means.
It’s generally a tiny label like “Minimum 5L” or something, near the nozzle, or on/below the meters.
I’m not from the US so my biggest surprise here is that you don’t get separate hoses for each grade.
Imagine getting Diesel in Germany. “Sorry, that was actually 15 liters of regular gas. ¯_(ツ)_/¯”
Edit: Ok, it’s not as bad as I imagined, since this picture seems to be about E15/E10, not diesel/regular.
diesel absolutely DOES get a separate hose, every time
Diesel are often entire separate sections of the gas station.
Most of the pumps in the US have the same hose for 87/89/92 octane pumps that are E10 (10% Ethanol) and if there is a higher ethanol like E15 or E85, they’re usually a separate hose.
I’ve seen pumps that have individual hoses for each octane grade in the US, but they’re definitely uncommon, at least where I am, and I believe more prevalent on older pumps. But diesel always has its own hose.
Thanks for the explanation! I wonder what they would do if they caught someone dispensing only 3 gallons.
Federal law states the punishment is a bare bottom spanking.
😳
Federal law states the reward is a bare bottom spanking.
FTFY
I’m sorry officer. Looks like I only bought 3 gallons. I guess you’ll have to…punish…me.
Probably nothing. I guess it’s possible if you kept switching back and forth between pumping a gallon of premium and a gallon of regular on different pumps to try to steal a few dollars of higher grade, they can use it to give you a ticket, but I’m pretty sure they won’t really care if you were just topping off a tank of gas with 3 gallons before a road trip.
I honestly don’t know what one does if one runs out of gas down the road from a gas station and doesn’t want to call AAA or similar. I assume that gas stations must keep a jerrycan or similar around that they’ll let someone take with a deposit.
I definitely wouldn’t want to be lugging more gallons by hand than would be necessary to get my car to the gas station.
You’d be amazed how many people learn the hard way that they first need to head to a separate store to buy a gas container, then head to the gas station. Most places could care less about keeping a container on premises because it is both a rare situation these days, and storage is at a premium in most stores. If you saw the back room or manager’s office, you would see the floor-to-ceiling stacks of inventory (usually drinks or tobacco products).
Most gas stations will sell small gas cans for exactly this reason
Most expensive gas can on the planet ofc.
As it’s a federal regulation, it would need to be the feds pursuing it. It’s highly unlikely they’d come after the individual. They would be more likely to pursue the gas station.
I’m guessing it’s more of a “if you don’t get the minimum, they’re not responsible for variation from the rated mix”.
Presumably, you buy a grade other than the E15 that doesn’t have the “minimum 4 gallons” restriction.
So, I don’t know what the deal is with E15 – what’s unusual there is the ethanol content – but insofar as high-octane blends go, and if that’s the factor here…I mean, while I realize that there’s a certain contingent of people who buy them because they think that they’re just better for their car, and for all I know that may dominate the actual market, in theory you’re supposed to only use high-octane fuels in cars with engines that require it.
I guess they’d probably function without it, but…
Generally higher octane works fine in most cars but high performance engines not configured to handle either type may knock with lower octane fuel (due to premature ignition with the higher compression ratio), and will generally put out (slightly) less power regardless due to timing adjustments the engine will make to accommodate the change.
Putting premium in a regular car that isn’t designed with higher compression ratios in mind is really just a waste of money.
Around here stations have a purpose-built plastic bag that seals after filling up and fits in the car’s fuel intake. It holds a few gallons, but I’m not sure how many.
It couldn’t possibly be illegal as 2/2.5 gallon gas cans are extremely common.
straight to federal pound-me-in-the-ass prison
I didn’t know this before and it adds credence to my feeling that it’s better to let my tank get below 1/4 full before filling it up, rather than continually topping it up.
The vast majority of cars run fine on 87 octane. If that’s what you’re using, then it really doesn’t matter if there is some 89 or 92 in the hose.
True, but my car needs 92 octane
Depends how much, but you’re right.
Lower octane that puts in higher octane aren’t burning the fuel because higher octane needs a hotter spark to burn it all so you’re essentially wasting money or slowly killing your catalytic converter by putting in a higher octane than what your car is meant to use.
On the flip side, lower octane in a car that requires higher means the gas ignites quicker which will cause knocking and can damage the engine.
There’s probably more to it than this, but that is what I was always taught.
I fill up when I hit 1/4 tank as well. Don’t wait for it to go below though, as it can be bad for the engine with deposits and other stuff in the tank.
I would hope your car has a fuel filter installed that would never let deposits get to the injectors. (Or carb on the off chance you drive one of the last ones on the road.)
So with modern fuel filters, there’s no “watch out for the crud at the bottom of the tank” phenomenon to worry about [anymore]?
You should be filling up closer to a third. The fuel pump is cooled by the fuel and letting the fuel run too low can cause more wear and tear on the pump, causing it to fail.
How fucking big are American canisters? In Germany the regular size is 5l, [Edit:
just shy ofa bit more than] one gallon.5l, just shy of one gallon.
5L can’t be shy of a gallon. 4L is more than a gallon.
checks
Yeah, a gallon is 3.7854118 L.
Oh…wait. You’re in Europe. I bet that you’re thinking of imperial gallons.
checks
That’s about 4.5 L. Still not the case even with imperial gallons.
When people are talking about gallons in the US, they won’t be using imperial gallons. They’re using the US gallon.
Well, I just typed “1 gallon in liters” into google and took the first number, because I couldn’t be bothered to deal with your system of measurement more than necessary. My point stands regardless of the exact volume of one gallon.
OF COURSE THERE IS MORE THAN ONE DEFINITION OF GALLON
Portable US gas tanks are typically 1, 2, or 5 gallon.
I usually just grab a 5 gallon (about 20L) can to fill up my lawn mower, throw some fuel stabilizer in there, and then I don’t have to go back to the gas station for a long time.
I do the same for my mower and mini bike. I can last a month on a 5g canister, well 5.5 gallons to the fill line according to the ⛽.
These signs also exist in the Netherlands, and the reason is because pumps are calibrated to a certain accuracy (say, 1%, for convenience).
But in the real world, you can get a lot of variation from temperature, to how long it’s been since a pump was used, to how full the underground tank is. They all made a difference, mostly at the start and end of pumping.
So you get a law in percentages, and you get a real world deviation in volume. Obviously, if your pump is short 50ml on 1 liter, you’re off by 5% and breaking the law. But of you slap a sticker on, telling everyone they “must” get 5 liters, you’re off 50ml on 5L, a perfect 1% deviation and entirely within the limit.
But 8 gallon is BIG volume, damn.
In Canada ours have a sticker that says the amounts are calibrated to a certain temperature (15C I think), so I assumed it took that into account. I try not to think about how much it costs so didn’t over analyze it.
What happens if you try to fuel a vehicle with a tank smaller than 5 gallons, for example a typical small motorbike?
Just spray the rest on your car, the ground, or whatever. It’s like having fun with the water hose!
Free hotdog.
Removed by mod
If you do this though, don’t smoke. There is always a small chance of a freak gasoline fight accident.
I saw a guy filling a Home Depot bucket at the Arco earlier today. Now I’m wondering if it’s because of something like this.
Once I saw a guy filling up a plastic grocery bag while smoking a cigarette. I often wonder what he was doing
Or they were just taking it home to store. Which, y’know, will likely result in that gas eating the plastic bucket in a couple weeks because gasoline is incredibly good as a solvent.
Nothing. But you might not fall within the legally required accuracy, so maybe you’re overpaying very slightly.
Does this pump also dispense marked fuels through the same hose?
In my province of residence gas stations near farming communities often sell “marked fuel” (fuel with an added red dye in it) that are taxed less, and which are intended for farming machinery, road work equipment, boats, and other non-highway use only. If you’re caught with red-dyed fuel being used for any other purpose you can be charged with an offence, and levied fines or other penalties.
If you dispense a small amount of regular gasoline after another purchaser had bought marked gasoline, the dye in the fuel remaining in the lines likely isn’t diluted enough to tell the difference — and you could (hypothetically) then be charged with possessing marked fuel without the proper paperwork.
(Anywhere I’ve ever seen marked fuels sold usually has a separate hose for the marked fuel to be dispensed from to prevent this from happening — but I don’t know your gas station or where you live, so maybe they rely on dilution rather than separation to differentiate?)
The rural area i live in has pumps thst give non-ethanol fuel but is not dyed and costs more than the e85 they sell. No placards anywhere stating any federal fueling minimums either. I routinely fill a 2 gallon tank of nonethanol for my old yard equipment and have never had an issue
I don’t think marked
girlgas necessarily has no ethanol. It’s just tax free.Edit: typo
how often do the police pull people over to check their fuel color though?
It is not uncommon for semi trucks and other heavy haul vehicles to be checked. They can frequently hold several hundred gallons of fuel. So there’s a real cost saving using off-road diesel. Though if I remember correctly fine is $10,000 for the first offense so that wipes out your savings pretty quickly.
i am learning so much today
Yeah last time I checked off-road diesel was about 50 cents cheaper than on road diesel. So 50 cents times 100/200 gallons, can save you some money. Especially if you do it regularly. And I totally didn’t check to see if it was worth running in my diesel truck, you have no evidence.
Oh and for when they check, it is usually at DOT weigh stations. If they decide to do a random check or they see something wrong with your truck. They will do an inspection and usually dip a tank. Or at a traffic stop, it is usually only a state patrol that bothers, but if you’re unlucky enough to get pulled over in a semi truck. It is not outside the realm of possibility the officer will decide to dip your tank.
Hmmm. So if you’re a regular driver who’s driving a small diesel car or SUV they might never think to check the fuel.
Yep it’s very unlikely that they would ever dip a tank on a private vehicle. I’ve heard of a few people getting their diesel pickups checked, but it’s very uncommon. It’s also much harder to do you can’t directly dip the tank because of anti-siphon devices. You have to open the petcock on the water separator/fuel filter. So you have to know where that is you have to have a little container to catch the diesel in and you’re much more likely to get messy. It is not worth a police officer’s trouble really.
I’m definitely put off road diesel in my pickup truck a few times. Mostly when I was short on fuel and needed to get to town. Though I have known a few guys who run it regularly without consequence. Though it was mostly due to convenience opposed to tax invasion. They’re already on the ranch there’s already diesel fuel there and sometimes the boss is letting you fill up for free or more likely they are the boss.
I definitely wouldn’t pull up to an off-road diesel fuel pump and just pump it into my truck. That’s a little too obvious.
Easier to check driver color.
holy racist
About as often as they check how many gallons of gas you pumped.
I can’t say for Canada but in the USA I have never seen or heard of off-road gasoline. And I worked enough farms and ranches that at least one of them would have been using it if it existed. So I highly doubt this is an off road tax reason.
Edit - it seems some people maybe thinking I am talking about off road diesel. I am not, I am specifically referring to only unleaded gasoline.
I talked to a farmer in Kansas (near Colby, iirc) who had his own gas pump for farm/off-road use only, so it does exist here. Probably only found on pretty big farms though.
Just curious are you sure that was gasoline and not off-road diesel? Off-road diesel is very common and almost all farm equipment is diesel.
Good point, it was a long time ago, so I don’t recall if he said gas, fuel, diesel or something else related
I know you weren’t directly questioning my assertion, but in case anyone else happens to think I’m just blowing smoke: Coloured Fuel | DriveSmart BC.
Yep definitely not questioning your assertion. I try to do my best to not tell other people how their country works when I don’t live there, I’m mostly successful
No, it exists in the States. I used to be a truck driver, and we used marked fuel in our refrigerator units all the time since those engines are not powering a highway vehicle.
Really where? I’ve straight up asked farm fuel delivery services and they said it was not something they could provide. Interesting, I wonder if they were being lazy or it has to do with state taxes or what.
Edit - your reefers weren’t diesel? Most of the reefers I’ve ever seen had those little three-cylinder Perkins in them. But I’ve never worked as a trucker so I wouldn’t know for sure.
Yes, they were diesel. I don’t think it’s as common nowadays as it was when I was driving because I don’t see the separate off-highway pumps at truck stops anymore. It was always a common thing at smaller, independent truck stops, and those are all but extinct, it seems.
So you are talking about off road diesel not off road gasoline. Correct? I am very familiar with off road diesel, but I can’t find any reference to off road gasoline
Off road gasoline is rare and varies by district, here in Canada I grew up in BC and we had “purple gas” and “red diesel” but purple gas was only sold at very specific stations, usually near parks where people would put it in ATVs and boats.
Now I live in SK and we only have “dyed diesel” which is your standard red farm stuff. You can get a discount on gasoline delivered to a farm tank, but there’s no colorant added and almost nobody does it anyways, since gasoline goes stale and isn’t used in farm equipment.
Myself I converted my remaining gasoline equipment to propane and run heating propane in it. The only gas burners left are lawnmowers, quads and a farm truck.
Yes, I’m talking about red diesel.
I used died gasoline in a boat.
Is it common? I have never been a boat person.
It’s not uncommon, but not as common as died diesel of various types. A marina in Orange Beach Alabama sold a died diesel called locomotive diesel that is apparently different in composition from agricultural diesel.
Sadly the tax advantages is absorbed by the vendor as they are located in the water.
Interesting, what color do they dye it.
Looking up locomotive diesel. It didn’t switch to ultra low sulfur for 5ish years after over the road diesel. I would bet it has a higher Cetane, probably some closer heavy fuel oil.
It was dyed the same red and slightly cheaper than other marine diesel.
I got curious so I duckduckgo’d that shit.
Thank you for sharing the link. Here’s the relevant bit from the article:
Most gas stations don’t want to install new tanks just for E15. Instead, they’re installing blender pumps, which mix the ethanol and gasoline together in the right proportion depending on which one you want. But there’s a problem: if you pump E15 into your car, about a third of a gallon remains in the fueling hose when you’re done. If someone comes along, switches to E10, and buys a single gallon for their lawnmower, they’ll get a third of a gallon of E15 and two-thirds of a gallon of E10. That comes to about 11.7% ethanol, and that might be enough to set your lawnmower on fire.
So the EPA produced a new rule: if you sell E15, you have to require your customers to buy at least four gallons of gas regardless of what blend they’re buying. That’s a big enough purchase that the residual fuel in the hose is too small to matter
I totally won’t use this knowledge to try to fuck with Sheetz.
So… what are they gonna do if you don’t fuel enough? Is it just up to God to not let someone else fuck up their equipment after you’ve fueled up?
Sounds like the warning label is about all they will do. Guess it’s one of those situations where if you ignore the label or don’t read it you might be penalized?
Except the warning is on the e15 and not the standard gas.
So it doesn’t matter if I buy 1, 2, 20 gallons of e15… As an e15 buyer I get the chance that it’s more gas than ethanol.
The warning of 4 gallons needs to be applied to the non-ethanol blend gasolines, as those are the ones at risk!
and that might be enough to set your lawnmower on fire.
Ethanol burns hotter?
No. It does degrade some fuel system components on fuel systems not made for it.
It also gums the fuck out of fuel injectors, and you’ll notice a drop in gas mileage Dependant on the blend. Its pretty awful shit. I don’t know why the hell it exists.
I think it exists because people have an unreasonable price sensitivity when buying gas. They will drive miles out of their way to save a nickel a gallon. I also think they don’t really have a good understanding of mpg factors. I was told by one guy purchasing it that he gets better mileage on it(which we know isn’t true)
Fucking 15% ethanol now? So they basically just raised the price of gasoline 5%, and reduced the fuel efficiency of everyone’s vehicle, without so much as a peep. Where is this?
E15 is a different blend of fuel, it’s not at all gas pumps and regular 87/89/91 octane level fuel is still available (because not all cars can use E15 like the sticker says). Sheetz stations sell it in my area around Raleigh, NC.
What an appropriately named station.
I would expect it to also be less expensive but they don’t show us that information.
I personally wouldn’t mind if my fuel mileage goes down if the cost is also proportionally lower.
Also, ethanol has a energy density of roughly 2/3 that of gasoline, so yes e85 would have 5% less energy than gasoline with no ethanol, not e10, which is what I see as the listed price in most places. When doing a price comparison, it should be against e0, not e10 if you are expecting a 5% energy difference.
Where I have purchased it it has been cheaper.
We also pay for it in grocery costs from crops switching.
Would you prefer they ban driving? we simply cannot keep going as we are, things have to change and you can either change your habits alongside it, accept that you have to pay more, or whine as you keep pumping poison into the air and contribute to your own early death from climate change.
Buying E10 fuel (a mixture that contains 10 percent ethanol) from a hose that also supplies E15 fuel (a mixture that contains 15 percent ethanol) must buy at least four gallons to protect customers following behind. Ethanol is hard on engines and less efficient than regular gasoline. E15 can even cause engine failure in smaller or older engines. So if you’re using a blender pump to buy E10 that sells both E15 and E10, the residual amount of E15 left in the hose from the previous customer could cause significant damage to those smaller and older engines—unless you purchase at least 4 gallons.
Hold the fuck up.
Customer A buys 10 gallons of E15.
Customer B buys 1 gallon of E10 from the same pump.
Customer C buys 1 gallon of E10 from the same pump and puts it in his chainsaw. If that gallon ruins Customer C’s chainsaw, it’s legally Customer B’s fault? What the fuck?
Forcing B to buy more gas than he might want, to protect the customer after him, because of the customer that came before him, is some horseshit.
The gas companies bought a law to exempt themselves from liability.
What, again?
Maybe these climate change purveyors should be forced to separate E10 and E15 dispensers.
Story of everything…
Source?
This fucking law right here.
Legally customers C fault. He needed to buy 4 gallons and fucked himself.
Why is it bad to have rules which prevent harm to everyone?
Nobody is forcing anyone to buy anything. You ever see a 2oz bottle of Coke?
That doesn’t prevent harm to everyone it just allows gas stations to use a single pump and shift the liability onto consumers.
If you can’t see the practicality, that’s on you.
Boo. If you’re gonna troll, at least make it interesting.
Nobody is forcing anyone to buy anything.
In the given example, is the gas station not forcing Customer B to purchase more gas than they may want or need? What if I have a chainsaw with a 1 gallon fuel tank? Now I need to not only buy more gas than I can use, but a container to safely store it in. (It’s also illegal to dispense gasoline to/from an unauthorized container!) Now if I use my chainsaw once or twice a year, I also get to dump out that extra gasoline because it’s gone bad by the time I need to use it again.
Do you have an ethanol chainsaw? Maybe an ethanol weed whacker? Got some links to these small ethanol motors?
E10 and E15 mostly aren’t ethanol. They’re 90% and 85%, respectively, gasoline, with the rest being ethanol.
Go on.
That’s a pretty stupid comparison. These aren’t prepackaged containers, and that’s a pretty key part of the terrible point you were trying to make.
Ok then, try to book an attorney for 10 minutes only.
This seems like it’s flipped around backwards. The picture says you have to pump more than 4 gallons if you are getting E15, but the explanation seems to explain why someone pumping E10 would want to pump more than 4 gallons.
I bet the real reason is that someone could pump a couple of gallons of cheaper E15, knowing they’d actually receive E10, leaving the next person to actually get that gas.
Ok, that makes sense, but why a federal law?
Why force companies to buy pumps that blend when you can force all liability onto the customer?
Gas stations can get away buying cheap blending pumps and if it breaks someone’s older car just shrug and say it must have been the previous customer’s fault, we’re not liable.
“We don’t care about service and quality. Oh, and we make it be your problem.”
It’s probably administrative law associated with DOT regulations. So yes it is a law but not quite in the same way you think of when Congress passes a law. Instead Congress passed a law that said DOT we give this agency the power to regulate these specific things. Go create a working committee and create some regulation. Administrative law is a bit more like civil law than criminal law. In general violation is just fine and they are handled by administrative law courts. Part of what makes them so different is they do not fall under the justice department they are contained within whichever agency has jurisdiction over that area of regulation. They’ve been affirmed to be functionally the same as federal courts, but can only sanction the guilty party in the exact manner the regulation says. Otherwise when the case is concluded and a party is found guilty is then referred to a federal court for sanctions.
There’s actually a really good explanation for this.
This is a mixing pump. It mixes ethanol into the fuel. Because the mixing happens before the part of the pump that measures how much is being dispensed, you need at least a few gallons to fully flush things out and get somewhere close to what you’re actually buying.
Nobody is going to come arrest you if you buy 2 gallons of gas. But the gas you get me not be the mix you wanted.
Which is it, up to 15% or up to 10% ethanol?
It’s 10% in the winter and 15% in the summer (at least that’s the legal limit), although I think that’s changing. So I guess they just said what the hell and put on both stickers?
Where I live you can get zero percent and even leaded gasoline…
Woah. I didn’t know leaded gasoline was still available anywhere.
Woah. I didn’t know leaded gasoline was still available anywhere.
General Aviation fuel (think propeller planes) use Avgas still uses tetraethyl lead, which is “leaded gasoline”.
They’re trying get rid of it, there’s a phase out target of 2030 for piston aircraft. Turbines jet engines already use different fuel.
So there’s a shit load of caveats. One there’s only a few places i know in the state that sell it. It’s supposedly only for small engine purposes, and it’s illegal to pump into a car. There’s daily limits imposed by the gas station and weekly and yearly limits imposed by the state I think, but I never looked them up.
Weve known Lead was poisonous since the romans and we decided to add a derivative of it to our fuel on a massive scale. We sure are smart.
The guy who invented leaded gasoline also invented CFCs, the refrigerants that punched a hole in the ozone layer.
And invented a bed with a bunch of wires and pullies for people who are crippled (after he got polio). Oh a good idea from the worst man ever you might think, NOPE this invention was also deadly and after a malfunction killed him.
Thomas midgley. He invented CFCs to replace the previously most commonly used refrigerants: Sulfur Dioxide and Ammonia which are both pretty nasty and should have been replaced… just not with CFCs. Leaded gasoline was invented to help prevent knocking and increase fuel efficiency. Today we use other additives and are better able to reform low octane hydrocarbons into higher octane ones with modern catalysts. Then as another commentater mentioned, he contracted Polio later in life and invented a sling and pulley system to help him out of bed.
We also use it to weigh down our fishing lines… because we’re that smart.
I think there might be two options to the right (yellow stickers) indicating eg 95E15 and 98E10
Ethanol is wildy bad for the environment and is raising the cost of food.
I read somewhere awhile back that it takes something like 3 gallons of gasoline (through running farm equipment and transportation) to make 4 gallons of ethanol. That coupled with ethanol being less efficient that gasoline and causes more wear and rear on vehicles probably means that if we ditched it altogether we’d probably the same carbon emissions wise.
Also, for every acre of corn raised to go into ethanol, that’s one acre not going into feed corn or other food crops so we’re effectively raising the cost of food via limiting supply and competition.
The only people that benefit are farmers that recieve substantial subsidies to grow it and government personnel who administer said subsidies and elected officials that campaign on taking money from you the tax payer and funneling it into these programs.
The cost to all of us is diffused, probably no more than a few tens of dollars taken from us via taxes so nobody is gonna go stand up to these people and demand that we end this subsidy. The benefit to them is very focused and large so they have every interest to keep the cash flowing their way. Every interest to take money from all classes of people but most damaging to the poorest of people since those dollars mean more to them than richer peoples.
This wildest part is that you who is reading this right now is probably outraged that this program is in place but the even crazier part is that you can substitute this with practically any and all industries and they are all doing the exact same thing but for the things that you agree with, are perfectly fine with keeping those subsidies flowing. After all, it’s only the other people that are greedy. The only real solution is to completely end all federal subsidies but I’m sure you’ll disagree and say that XYZ is necessary because it’s your special interest.
You’re not wrong about the whole corn subsidy switch to E85 being terrible. It was purely about getting Midwest votes specifically winning Iowa in the primaries. It is worth noting though that E10/15 is not intended as a replacement for gasoline like E85 is. The ethanol in E10/15 is both a fuel oxidizer and an anti knock agent. So it reduces tailpipe emissions by helping make a more complete burn and increases the octane of gasoline by two or three points meaning the gasoline has to be less refined.
Ethanol replaced MTBE, it is not clear how and at what level MTBE is toxic. But it is extremely water-soluble and has the ability to leak out of sealed underground tanks. This of course led to very easy contamination of groundwater and aquifers with MTBE. Which was probably a bad thing.
For anyone who cares MTBE replaced Tetraethyllead. And if I have to explain why lead is bad to anyone they’ve had too much lead exposure.
Spelling
Yeah, back in the nineties I was super hyped on ethanol, and then I found out how bad it really is. It was disappointing :(
It either violates federal law or it doesn’t. May is doing a lot of heavy lifting here. Not to mention there are signs for both up to 10% and up to 15%…
If the purpose of the warning is to make sure people get the blend they want then just say that.
This… Why is this sign ambiguous? To avoid improper fuel blends, dispense 4 gallons minimum, federal law.
Walking around may violate federal law. Depends on where.
Fuck you if you own a motorcycle, I guess.
My RV200’s tank only holds 1.7 gallons, and my CH50 will only take one. I guess I’m meant to just dispense the remaining three gallons onto the ground, then…?
From morocyclistonline.com:
Running your bike on E15 may cause your engine to run hot and could possibly damage your bike’s catalytic convertor as well as cause crud buildup on your valves and pistons.
Ethanol fucks up the rubber in my 1980s Suzuki carburetor. I wish I could find an alternative.
I feel you. E10 is the lowest content we can get anywhere around me. I have to ride about 90 miles to get to the nearest station with non-ethanol fuel.
There is Sta-Bil 360 which allegedly mitigates the effects of ethanol at least in storage. I always use it in my bikes overwinter, and I haven’t had any issues… yet.
Several stations around me have removed their mid grade option to sell E85 in that pump slot instead. You can have E10 regular, E10 premium, E85, or fuck off. I have seen a few shiny new stations on the interstate that only offer E15, which seems to happen most often out in corn country. I get that there’s only so much oil in the ground, but you’re right – there has to be a better way. It’s just probably not as cheap…
Yeah and which one of those are you putting ethanol in?
I think it has to do with how it’s dispensed. If the person before you bought regular fuel, the hose still might have residual fuel from the other kind, meaning you could end up with a different ethanol level than expected. That’s a fire hazard. 4 gallons is probably overkill but better safe than sorry.
Edit: basically, if you accidentally get half a gallon of 10% ethanol fuel and half a gallon of 15% ethanol fuel, you actually have 12.5%.
Has that always been the law and I just never noticed a sticker like that before?
Not sure how long it’s been a law but not a ton of places sell E15. I only ever see it on road trips personally.
https://afdc.energy.gov/fuels/ethanol-e15
E15 is available in 31 states at just over 3,000 stations. E10 remains the limit for passenger vehicles older than model year 2001 and for other non-road and small engines and vehicles that use gasoline, such as lawn mowers, motorcycles, and boats.
To put that in context, we have almost 200,000 gas stations. Like 1.5% sell it
Also this just happened: https://www.reuters.com/business/energy/us-epa-allows-temporary-expansion-higher-ethanol-gasoline-blend-this-summer-2024-04-19/
The decision marks the third consecutive year the administration has lengthened the period during which Americans can keep buying E15, a gasoline that uses a 15% ethanol blend. Sales are effectively blocked from June 1 to Sept.
Adding ethanol to gasoline is known to increase smog pollution in hot weather, but research has shown little difference between E15 and the more-widely available E10 blends.
how do they enforce that? seems undoable
I’ve seen a cop show in the UK, they had a long stick they put down your fuel filler and it captured a tiny amount, they pull it out and can tell by colour. Normal fuel is clear/yellowy and marked is usually red.

archaic and inflexible.
No, it’s working precisely as intended. There are so many layers of byzantine laws and ordinances in the US on multiple levels – federal, state, county, municipal – that anyone who really wants to is guaranteed to be able to find something to harass and/or arrest you for, no matter what. Probable cause can be rendered meaningless by making a humongous array of trivial things technically illegal.
Does your window tint meet the specific requirements for this county? Is your stereo 0.01dB louder than our municipal maximum? Are your license plate and registration sticker acceptably clean? Do your tires have the correct tread depth? Do you have a radar detector installed? Do you have an air freshener hanging from your rearview? Are you carrying your written prescription around with your pills? Is your pocketknife blade too long? Do your cigarettes have the wrong state’s tax stamp on them? Did you remember to sign the back of your registration card? Whoopsie doodle, this state passed a law mandating minimum headlight height from the road, too bad your car left the factory out of compliance. Could you step out of the vehicle for me, sir?
Etc., etc., etc.
Aleksandr Solzhenitsyn talked about exactly that in the USSR in Gulag Archipelago.
He said that in the entire time he was in the gulags, he never met one single person who hadn’t been legitimately tried and convicted of an actual crime. And the key was exactly what you describe - the Soviet laws were so extensive and byzantine that whenever any official wanted to disappear somebody, all they had to do was investigate them enough to figure out what laws they’d inevitably broken, then try them for that.
That’s how authorotarian scumbags implement a police state while maintaining a superficial appearance of justice and the rule of law.
And it’s guaranteed that American authoritarian scumbags know that.
While I see your point, given the devastating effects leaded gasoline has had on entire generations, perhaps fuel is a good thing to regulate.

While I agree with your premise, I don’t like that your list is what came to mind when you thought of unnecessary laws. Those are some of the best laws we have. It sucks being hypersensory and trying to live a real life, and literally 25% of the population is. With hyposensory people (another 25% of the population) just acting like we are all whiners for experiencing every sense as much as 4x as strongly as they do. “No one could possibly be that annoyed by something that barely affects me, they are just too sensitive”. Well, yes. Technically that is the problem, but our sensitivity is physical and not by choice.
You wanna tell me how you know when you’ve got damage caused by this and can prove a specific gas station has anything to do with it? It’s really easy for a gas station to just monitor it’s pumps.
Consider the practicality.
does this mean 2001+ OR flex fuel? or 2001+ AND flex fuel?
the former wouldn’t make sense as that doesn’t really exist, but if it were the latter then that’s a really ambiguous warning.
If your vehicle was made after 2001 OR specifically labeled as flex fuel
