Hey, sorry for this STUPID question I was wounderign about jet fuel...

Is it bad for our cars or not? I know it's a Kerosene based fuel with HIGH octain; but will it run with our piston engine or it'll kill it?

My friend is a Airplane engine machanic he said he THINKs it'll work our car won't take advantage if it because of Higher Octain and our engines doesn't even burn the fuell all the way to keep the enviorment cleaner running richer than leaner.

ANy how Sorry for a stupid question but I ALWAYS get mix answer like:

Yes it'll work and its higher Octain so its good.

-and-

No It's Bad it'll Kill your car.

Wont work unless you are making some serious power

"No It's Bad it'll Kill your car."

Jet-A is basically kerosene, very low octane...like 20, would work in a diesel engine but will destroy your gasoline engine.

AvGas which comes in 80 or 100LL; 80 wouldn't work cause octane is too low, 100LL has a crapload of lead in it which your engine isn't made for.

So if you had a 60's muscle car, you could pump a few gallons of 100LL and fill the rest with premium car gas and it would run fantastic.

i don't even want to know how you know so much about gas

Gas smells good, but not so good when it gets poured on your eyes so be careful.

100LL AVgas works great in all my cars, but the GSX likes it the best! I fill it up everytime I visit the FBO...

Do not put jet fuel in your gasoline powered vehicle!

Can you say...serious detonation! Burned valves/pistons, serious pitting of the head...enough said.

HEHe that what I thought... Well I REALLY thought its low octain because at higher altitude you have less )2 so Lower octain would burn easly and faster for the high ammount of pressure you need to propell so much thrust.

THanks for the reply! =P

Diesel and kerosene both have C-tane, not octane. octane is the ability to resist detonation, C-tane is the the opposite, the more c-tane the more willing the fuel is to ignite. Diesels work by heating the air so it is hot enough, 750 deg F and higher, to combust the fuel, thats why they sound like they are knocking, because they are.

If you tried jet fuel in a boosted motor, you would blow it up almost instantly :dead:

ok, here's the basic lowdown. jet fuel burns, a lot, for a long time, and very very hot. If you get enough of it burning in bad ways, horrible things will happen. jet fuel burns hot enough, long enough, that if you poured some on an engine, it could melt the block. I spent 3 years in the AUX. of the Air Force. the problems i had with jet fuel is that when we used it to start a fire, it burnt everything down really fast, and then the fuel took forever to burn up. trying to run jet fuel in a cylinder engine scenario creates an uncontrolled explosion, with a napalm like effect. basically yes, like everyone else is telling you, it will kill your engine, completly, and everything near it. the fuel will still be burning when your valves open, and it'll shoot fire all the wrong ways.

JP-8, Diesel, "Jet fuel" are all roughly the same type of fuel. So NO, simply stated puting diesel in a mogas car will make it not run anymore.

Now "Race fuel" also used in airplanes, but only prop planes, is a very high octane fuel. Generally 100/110 mon or ron, depending on how it is rated.

Now MON or RON are simply two rating systems for fuels. One is more exact than the other, but being more precise means it is more expensive, so not everybody tests there fuel that way. So in the states you see your listed octane as MON+RON/2 that way they just average the two together and give you the best of both.

So to simply answer your question "jet fuel" is mainly a diesel fuel, I have put it in my HMMWV and it runs fine. Put the diesel in your moGas car and you will hate life. And in the racing world people say "jet fuel" but they mean airplane fuel, big difference between the jet and the airplane. So for a standard propellar style airplane it generally runs off of really high octane, 100/110+, which would hold off detonation really well.

Hope this makes sense.

As for the airplane mechanic, what airline does he work for?
Cause whichever one it is, I WON'T be boarding their planes...... :scream: :shock: :shifty:

Not exactly. As mentioned above, aviation fuel (avgas) for piston-engine airplanes (most small propeller planes) comes in a few flavors, 80 (red), 100LL (blue), and 100 (green).They *all* have lead in them, and pretty much any lead is too much for a stock car engine. Even 80, which has the least amount of lead, contains 0.5 grams/gallon. Unleaded car fuel contains 0.001 grams/gallon. So while many airplanes can (and do) use car fuel, cars cannot use airplane fuel. (At least not without contaminating the engine and especially the catalytic converter with lead.)
