I was an aircraft mechanic who specialised in jet engines, piston engines, recip engines, turbo props etc.

Av gas wont hurt your engine, it is however illegal to use in some locations, go figure, put it in your car and drive and the pollution is illegal, put it in a plane and pump it out in copious volumes and its perfectly fine.

We had 44 gallon barrels of the stuff and ran our cars in the 80s all the time on it, when you have to do fuel cell work in a plane, it has to be defueled, the fuel that comes out is not allowed to be re used in a plane, so it gets disposed off, most aviation fuels wont work in a car but the av gas does as its designed for piston engine planes
