Re: hardened valve seats L78
A pilot friend of mine recently told me the newer planes require the higher octane fuel (110). I would have thought the reverse. My reason for going to AVgas is that I'm told it doesn't deteriorate in the tank over the winter like pump gas does. We'll see next spring.
I bought ten gallons of TORCO 112 earlier this year for $5.25/gal. Won't do that again either. Ran great and smells terrific but a little stiff on price. I normally run 93 octane and a can of booster with 2 to 4 degrees advance and have very little ping.
