I would like to get some data from as many people as possible. It will be about another two months or more before I get to the gas station to time how long I spend there so I need your help. Here is what I want from you. I want you to use a stop watch. Start it as soon as you enter the gas station property. Pump your gas As soon as your car leaves the gas station property stop the stop watch. Come back here and tell me..... Total time spent at the gas station. total miles on that tank.
