I agree, and more to my point regarding "negligible differences", even a 20 degree swing is not enough to be noticeable at the pump.

If my math is correct, roughly 2.6% change between 68f and 104f.

If that is linear, 0.07% per degree(F). Realistically, the metered fuel temperature my vary by up to 10 degrees (guess), so maybe a 0.7% inaccuracy IF there is no temperature correction being done on the fuel volumes.

Larger fuel purchases will diminish the inaccuracy as only a few gallons are stored above ground at the pump.
