I wanted to know what type and brand of race gas your running?
He is asking about race fuelsExxon or Sonoco mixed with a bottle of lucas octane booster in every tank full!
MS109 is probably the most popular unleaded race fuel.
I use a private label version of VP C12. It is called 112 Blue. I have ran 22 gallons through, maybe a 1/3 to 1/2 of that ended up mixed with 93 after my track visits were over. I normally buy 5 gallons and put it in at the track. I either time the gas to be at 10 miles or less to empty at the track or use the fuel drain kit to get it there. Say what you will, but I have had no problems with the factory O2 sensors so far. First hand experience. It has served as a nice option for me and will until I go with a fuel system and injectors for E85.

Also, make sure your car is tuned for the exact fuel youre running. I tried running c20 on a 93 octane tune and the car was acting up a little bit.
I have no idea. It is plain old leaded, 112 octane.Is it the same thing as Sunoco Supreme 112?
