My formula vee engine builder, Mike Palermo, (Peak Performance),
strongly recommends avgas for FV's. We use 100 octane low lead - a
Vee's compression ration is ridiculous even for a street car - and it
burns as clean as unleaded. It's other principal virtues are that it's
stable and of good quality anywhere.
