I run a special brew Helicopter AV gas. Its designed for Turbo Prop engines, has no Glycol as helicopters dont get high enough & you only get it from a tanker, heaps of lead & has a 108 rating. engine definately runs smoother on this brew than Ground Tank AV gas. Somebody is yanking your chain, or you are trying to yank someones. Aircraft fuels boil down to these choices Jet A, Jet A-1, Jet B and Avgas. Since the first 3 are kerosene based for turbine type engines, that means any piston driven engine runs Avgas. And there are no special "brews"

Boy, please don't advise other people when you don't know what you're talking about. Turbo props are jet engines and burn Jet A which is kerosine. No lead and the octane is around 30 or so. Certified piston helicopters use the same AV gas as airplanes if that is what their type certificate says they have to use, there maybe some with a STC to use car gas. sorry, i wrote from my phone & it did some auto correct, i had written turbo piston but it decided to write something else. this gas is not the same as std AV gas & it's brewed in the tanker & only used on select helicopters down here. it looks like AV gas, but the smell is slightly stronger. AV gas has a rating of 100, this is 108 & as stated before, has no glycol. you need to chill a bit dude.

Uhmmmm what fairy dust have you been smoking? Turbo props run a blend of Kerosene called Jet fuel, Avgas 100LL is 100 octane, it has a lot of lead in it, enough to get lead fouled plugs.... I run a special brew Helicopter AV gas. Its designed for Turbo Prop engines, has no Glycol as helicopters dont get high enough & you only get it from a tanker, heaps of lead & has a 108 rating. engine definately runs smoother on this brew than Ground Tank AV gas.

Mogas is basically unleaded gasoline, same as what is in a car.

Add no oil into the fuel X2, lowers the octane, will knock at lower temperature and pressure limits.

I was talking with Dick Weinle the owner of Edgewater drag strip here in Cincinnati. He is a pilot and keeps planes down at his drag strip along with avgas. I am going to fly his plane here soon and am going to pay him for avgas. He tells me that 100LL avgas is rated differently than car race gas and that 100LL is like 112-113 auto race gas? I really have no idea to be honest, but he should know since he tells me he buys it 8000 gallons at a time and he has had it for many years at his drag strip. I believe he sells it to the racers for there race cars. Anyone ever heard of this difference in octane ratings?

I have heard the 100LL is rated differently and is higher than 100 octane, but no one could tell me what it actually is.
FWIW...I have an old friend that ran a 468" BBC that was 13:1 w/ 2 stages of nitrous for YEARS on nothing but 100LL w/ no trouble.

I bought a new mod vp engine from Mercury Marine in the late 80's and 100ll was the recommended fuel. It was a high performance outboard engine.
