Today, I was at my grandfather's house and my car was low on gas. He said I could put some of his gas in my car. He accidentally gave me the wrong tank to pump it out of, and I put fuel in my car that he uses for his small plane. It never ran better until the engine exploded. FML

(+2)ummm
aviation fuel is the same as regular gas except higher octane like race fuel
the engine wouldn't blow up
the pistons may chip but it would still run even if you threw a rod
(+4)ummm....
if you put airplane fuel in a car
it wont blow up...
it just flies away

(+1)To your information, many model air planes fly on methanol, which is more ore less pure alcohol!
it will damage the car.
My dad has a plane with a 5cc model air plane engine, it runs on methanol and puts out about ½ HP, imagine then what it would do to a normal car!
(0)Small aircraft fuel (100LL) is simply leaded gas with a higher octane rating. A car will run fine on it. The effective octane of 100LL using the automobile octane rating is something like 115.
Way back when, I filled up my gas tank with aviation fuel a few times to go racing. The most notable effect was that the engine ran amazingly smooth. On my car, with moderate performance modifications, I had to check my tach to make sure the engine was running.
Aviation fuel is leaded gas, so it will damage some things, such as the O2 sensor and catalytic converters. That's the only reason not to use it. Even if you damage both, the car will continue to run and drive, it just won't be running perfectly for emissions, because the computer won't be able to sense how much fuel is going out the exhaust (the purpose of the O2 sensor), and the catalytic converter won't clean up the exhaust as well.
I've known people in a whole variety of cars that used it, as well as motorcycles and other gasoline powered equipment.
Now, if that was Jet-A fuel, it would likely be a different story. I don't know how many people would have Jet-A at home, nor how many would call their grandfather's jet a "small plane". Hey, if you can say "Oh Grandpa has a small plane. It's a Gulfstream G650", I want to go hang out with Grandpa for a while. :)
Some people mentioned it may be fuel for RC airplanes. Did he have a 5 gallon can of that stuff laying around?? That'd be enough to last an RC person a lifetime. :)

(+1)i gave you a thumbs up. because the way you commanded us was pretty cool.
anyways, not sure how much i believe this. it happened in csi, and the whole car blew up..

(0)that sucks, but your grandpa can probably buy you a new car.
he has an airplane, ffs.
also, cash for clunkers, amirite?
(+2)I'm calling a fake. Your grandpa has two gas tanks in his garage, and didn't label them? His car would "blow up" if he used the wrongone. Also, if your car blew up, wouldn't you have died, and we'd have heard about it on the news?
(+1)Yeah, he would have noticed that the gas smelled different.
#10 - On 08/23/2009 at 12:57pm by Captain_Jello
(+2)For all you haters: The gasoline used for airplanes is much higher octane, like 105 or so. When you put that in a normal car, it runs great, you get more power, but the engine overheats. So the term "blowing up" means that the engine overheated and seized up, possibly a cracked head. So he would not have died.
Dude, just pay attention to your car.

(0)Higher octane does not give higher power.
Higher octane gives higher resistance to knock, which means it can be used in higher-performance engines. Putting high-octane fuel in an engine made for regular-octane fuel doesn't do anything except waste money.
#35 - On 08/24/2009 at 12:25am by therealmike
(+1)Aviation gas is 100 octane. Engines with high compression need higher octane, but engines with lower compression are unaffected. Higher octane gas won't give you more power and it won't make your engine fail. You can always use the lowest octane your engine will take without knocking. For almost all cars, this is regular. If you buy higher octane gas than that, you're just wasting money.
As for airplane gas, unless there's some other additive in auto gas that your engine needs that avgas doesn't have, then there shouldn't be any harm.
Finally, avgas is like $1.50/gallon more than auto gas.
(0)They should really do a Mythbusters episode based on FMLs, I want to see if most of these are bullshit
(0)FAKE! av gas is usually 100LL witch is 100 octane and LL stands for low lead, and they put lead it the gas to help prevent pre-ignition or detonation in piston engines for aircraft! unlike regular fuel for cars. also av gas is usually blue sometimes green and has a slightly different smell!!
(0)To all you guys screaming fake didn't you read the FML rules? Please stop screaming fake just stfu read and move on if you don't like it.

(0)Just but some sugar in the tank of ur grandpas plane see how he likes that when he's out flying around
(0)this reminds me of the family guy episode where peter tries to be a redneck and siphons airplane fuel into his truck in hopes of flying. lol

(0)ok #16 depending on the wear on the engine yeah and how he drive yeah it could cause a piston to blow through the engine wall jet and racing fuel...different. regular car engines arent meant to have that kind of fuel pushed into them without the right mods and upgrades. maybe when the op said his engine "blew up" he meant he blew a seal. fucking assholes...give the guy some credit. so what if he grabbed the wrong can labled jet fuel and blamed it on his grandfather
(0)Another fake one.
Perhaps learn something about fuel first before you post OP.

(0)Complete bullshit.
Avgas primarily is simply dramatically higher-octane than standard gasoline intended for automobiles (and tends to be well over 100 octane). It'd be LESS likely to 'blow up' and more likely to simply sputter and die in an engine not built/tuned for it, as octane is the measurement of KNOCK RESISTANCE, not combustability. It's how well it *resists* premature/spontaneous ignition (knock), not how well or clean it burns, or how much potential energy is in the fuel. You get *lower* gas mileage with higher octane, as it takes more fuel to produce the same amount of power... the trade-off being that it's more stable and predictable under extreme conditions, allowing a performance engine to be tuned to tighter tolerances.
In addition, pure methanol/ethanol requires a 20% richer fuel/air mixture to burn properly... and most of the 'damage' caused is due to the fact that alcohol burns cleaner (doesn't leave deposits like gasoline does, which help seal up failing gaskets) and is anhydrous; with cheap seals it can literally suck the moisture out and denature them. In any case, in a standard engine it AGAIN would simply sputter to a halt and die, no explosion.
The only way this would 'blow up' is if he had a diesel engine and got the wrong can and put gasoline in. Then it'd go off pretty spectacularly. And pretty damn fast.. it wouldn't run better, then pop.
(0)Race fuel is either methenol or 120 octane fuel the teams can chose between those 2. And it burns so hot in an average engine that once the engine get warmed up the heat of the last power stroke will ignite the next power stroke even if u cut the spark (this is wat turning the key does) Im not sure about small plane aviation fuel but I no jet fuel has kerosene mixed in it so it burns even hotter and no his engine wouldn't lotteraly explode but it would melt down and either sieze or drop a cylinder and to the idiot who sayed putting gas in a diesel will blow it up do some reasearch on deisel engines will u I'm a diesel mechanic and I've fixed tractors that stupid ppl put gas in instead of diesel they don't blow up they just don't run. Compression ignion fires the fuel in at the right before of supposed to ignite to prevent preignition gas simply won't ignite though compression...well it will but not on every stroke it becomes sort of hit and miss and if ur lucky it might run really shittily but most likely it won't
(0)It probably didn't blow up, it probably overheated and he didn't notice, and it's also rather likely it seized. If you've watched any of the CFC videos where the government murders good engines, then you can see the similarities watching an engine seize in a certain way to being "blown up." Not saying it's definitely not fake, but you all are looking a little too hard at this.

(0)100LL aviation gasoline would not cause the engine to blow up. By definition it is a higher octane and more stable than car gasoline. It would NOT cause the engine to overheat....in fact, a lower octane gas would cause overheating from preignition and engine knocking, etc. A higher octane fuel like 100LL would have the opposite effect, then.
Like it's already been mentioned, yes the tetra-ethyl lead in the aviation fuel would mess up other parts of the car (O2 sensor and cacalytic converter). You did not put 100LL into your car to make it "explode".
The only thing that I see happening is if you put Jet-A fuel into your car. While this is usually used in jet engine aircraft, there are diesel conversions for some aircraft, such as the Maule series of aircraft. For someone that is used to airplanes being 747s, a Maule M-7 is definitely a "small plane", and I do know of some people who keep Jet-A on their property in the country because they do not visit airports with fuel services often. This Jet-A would then mess up your car engine very severely.

(0)by small plane did they mean like RC plane? because if it was, it would have been nitromethane, which would absolutely mess up the engine... or if it was race gas with a high specific gravity and leaned out...

#41 - On 08/24/2009 at 3:53am by TheIrishJaneDoe
(0)LOL! props to your gramp for having his own aviation gas. And aviation fuel is 110 oct. and low lead, not unleaded. normal gas is 97oct. and unleaded. So it might blow a piston, for all the non-believers here.
