Supposed to be more " stable " than automotive fuel.--------------If your local airfield will sell it to you then you should give it a try.
Aircraft engines generally do not run above 3000 RPM-----------Not sure if aviation gas could be called " performance gas "--------The lead makes no difference on a 2 stroke.
My question is what would be the advantage of spending twice the price for fuel for a slight increase in performance. Also what would be the long term effect burning leaded in a unleaded engine it seems to me you looking for trouble, definately investigate it further before you chance burning up your engine.
AV gas is not going to give an engine a " performance boost " all by itself.-------There are many reasons one might use it in an outboard !!--------------Much is known from experience and much can be learned using " google " on the subject.--Please note-------I am NOT calling AV 100 a performance boosting gas !
I'd ask around locally where they sell regular gas without ethanol... There are several places in my area that sell non-ethanol gas... It seems to cost just a little more than the "premium" at the pump with ethanol. You are correct, AV gas has no ethanol as AV gas has to endure high altitudes which is a low air pressure environment. The reason AV gas has no ethanol is alcohol has a lower boiling point that true gasoline. Many airplane fuel pumps like outboard fuel pumps are mounted at the engine so theu SUCK instead of PUSH if they were mounted in the fuel tank like a car. THe sucking further can reduce the pressure on the fuel and, if extreme can cause a vapor lock. As far as the octane goes... the higher the octane the slower the fuel burns. Some high performance engines are designed to harness more power from a slower burning fuel. In regular outboards... no realistic performance enhancement is had with ultra high octane.
