Just so everyone knows, Precision Autosports will have 100 octane unleaded race fuel on hand for approx $6.50/gal. I highly recommend that anyone with higher than stock boost consider at least mixing this 50/50 with pump gas in the classes where race fuel is allows (all but Stock class).
For most people this will mean having somewhere around 1/4 tank of 92-93 and then adding 4-5 gal of 100. This is unleaded fuel so there will be no detriment to your 02 sensors and it will raise your octane to about 96-97. This will provide you a margin of safety for the weekend as well as allow some people to pick up a few HP without significantly altering your tune.
I always recommend racing with 1/2 tank of gas to avoid fuel starvation in the last rounds! The faster your car the more important this is. For stockish cars on street tires you may run the tank lower if you want to save a little weight.
You'll need something to transport the fuel in as it is dispensed from a 55 gal drum. (Or borrow Duane's. He won't be using it for anything....)
