Check out what Shell has to offer in race gas or Rocket brand race gas as well as VP Racing. What I have learned about running Av gas is not good for cars, bikes and boats because 1. Av gas has a different specific gravity can or will cause rich or lean conditions, 2 its formulated for higher altitude running conditions. 3 its formulated for slow steady rpm running conditions.

All of the racing at Reno is done right on the deck, so what is your take on these fuels? They are def not mixed to run at attitude....

I have been mixing av gas with pump gas forever. In my new boat Teague recommends mixing av with pump, my motors are designed to run on 91 but are on the edge and just a bad tank of fuel from detonating. That said, I run 40/60 av to pump and add some marvel oil in as well. Current motors are injected 5 litre whipples

I buy Avgas at the local airport by the 55 gal drum for my "ultralight" Lol (that I dont have) Have Mixed it up to 50/50 and boat runs awesome. BBC's 9/7/1 comp, alum heads, pretty big rollers. I have WAY more confidence in the quality of mixture in AVGAS than the crap you gonna buy at any gas station or pump.

My all original 63 Cadillac LOVES the lead, and high boost air cooled street motors seem to like it too, but it's not without it's headaches. Honestly the only reason I ran it is because it was very very easy for me to obtain.
