I may be wrong, but I think the math is incorrect in that example. I believe fuel cars use about 12 gallons per run (close?). If you made 4 qualifying runs, and won, that's 8 runs, or 96 gallons per event. If you won all 24 events, let's call it 2400 gallons/yr., w/o testing. 2400/42 equals roughly 57 barrels, multiplied by $300 equals a bit over $17,000 in price increase for the season. Did I screw up my math?
