I did a fire training with the ALMS safety team a few years back at Sebring. We started with lighting 1/4 gallon of 100 octane (15% ethanol) race fuel then by the end we used 1 gallon spilled on the concrete. The 1 gallon fire was over 20 feet high and took 20 seconds for a volunteer to put out with AFFF-AR suppressant. That demonstration woke all of us up very fast considering the cars carry upwards of 19 gallons.
