factual error error in goofs

I've been to the gas station next to water Wizz and used the same pump. In the goof it was mentioned that the fuel nozzle was diesel being inserted in the station wagon. Although most gas stations now indicate diesel fuel with green nozzle covers, that particular gas station used to be a BP station, they had green nozzle covers on all nozzles. If you look at the pump, there is no selection for diesel on the pump. I tried to get my teenage son to run from the gas station to water wizz, but he refused citing that I am insane.
