Trouble is, they have to be torn down and carbonized with very low hours which once the plane is N Numbered, you can't do your self unless you have a Power plant rating... That get expensive... My friend has 560 hours on his Top 80 engine running premium auto gas and Amsoil Saber 2 stroke oil.. He said 100LL users go about 50 -60 hrs and they are installing new rings and pistons.. He sees it like clock work..Two stroke aviation engine maker disagrees with ya.
"Aviation Fuels
It is possible but not recommended to use 100LL AVGAS, since the the lead content will increase deposits in the combustion chamber and on crankshaft ball bearings, inducing premature wear. Its higher octane rating does not bring any significant advantage to the engine's operation"
