Jet engines, including turboprops (all properly called "gas turbines") run on a fuel(JET-A) similar to kerosine (although in fact they are capable of running on almost anything that burns). Piston engined airplanes, like small private aircraft or WWII vintage fighters or old DC-3's,etc., all run on gasoline similar to auto gas. ("80" motor octane av gas is in fact very similar to auto gas, except for having somewhat lower vapor pressure. "100LL av gas" is just like "80" except that it has lots ot tetra ethyl lead added to raise its octane rating, for use in high compression engines.) Aviation gas is no more "pure" than car gas. By the way, the LL stands for "low lead" which is something of a joke since it has more lead in it than car gas ever did -- just that it replaced "100" which had even more lead!
