Bonjour Alain,

 

We have used 93 octane car gas WITHOUT ethanol for 1600 hours over 8 years. I would NOT use any fuel containing ethanol in the plane and I try to avoid it in my car.  Here in Virginia we can still get gas without ethanol but we test for it each time before we fill up our jugs. On the road, we buy avgas, but on average, I’d say that about 75% of the fuel that we use is car gas. We use no special procedures, just normal operation. Our engine is an O-320 with standard 8.5:1 pistons. I would not recommend using 100% car gas in the big bore engines, turbocharged engines or engines with high compression pistons.

 

I have inspected the interior of the tanks with a fiber optic scope and have noticed no deterioration of the tank sealer or the exposed hysol.

Bill ,
which type of auto-gas do you use,how many octanes,do you apply special procedures or do you run your engine the same way you do with 100LL ?
