I budget a full tank for the day, 10+ gallons for 100 minutes of on track running. Makes sense, some very rough math follows: locally average speeds for non-premium cars are around 60-70mph (~1mile/minute), average fuel economy is around 10mpg, so you pretty much end up at a bit more than 1 gallon/10 minutes. A conservative estimate would be 1.5 gallons/10 minutes, so I'd be bringing 15 gallons to the track, ~13 in the tank and 2 on hand or however it shakes out, 10/5, 7/8, whatever.
If I arrive at the track with a full tank (or as near as possible from the nearest gas pump, usually <25 miles, puts me at 12 gallons in the tank) I'm solid but will need to fill up before heading home (usually same station on the way out). Someone more aggressive than me may be cutting it a bit closer if not outright needing to top off a gallon or two to finish the last session and get to a station.
