Once I almost put E85 into my Truck!
I wished all gas stations have a standard color coding, like Shell did with the Vpower campaign(the V-power nozzle area was red and yellow, the rest were just plain plastic black) and such as kerosene (blue)
"fuel" stations are just going to get more complicated, instead of gasoline with the three octanes(87,89 and 93) you got propane,natural gas, Normal diesel, the new low sulfur diesel, E85 and "racing gas"(aviation fuel for the Terrafugia) and problably electrical outlets.
...not to mention the "snack" fuels on the inside of the store.
