It seems that everyone has an opinion on the use of AV gas in a race engine.
I've used it for a few seasons with great results. My Alfa has 11.5 - 1 comp
ratio. I have no preignition and the last leakdown indicated 20 + races with
no need yet for even a valve job.
My aviation mechanic buddies swear by it pointing out that the demands of an
airplane engine far exceed the needs of the average vintage race car.
My engine builder murmurs some incantation about additives, but he's only
repeating what he's heard.
I pay $2.15 a gallon for 110 leaded, less that pump gas on the West Coast.
Opinions, facts, incantations ?
