More and more, as I review new vehicles, and they need fuel, I open the gas tank flap all set to unscrew the gas cap, but there is not one there. There is a small trap door, that you can't push in with your finger, yet when you stick the gas nozzle from the pump in, it easily inserts. Welcome to capless gas tanks. Ford really pioneered capless fuel fillers on the 2009 Explorer, now many automakers use them including GM, Fiat Chrysler, Honda, and others.


I have talked on the air about a lady who ran out of gas in her Chrysler 300 and tried to put fuel in her car with a gas can. It ran out on the ground because she did not use the plastic fuel filler funnel that came with the car.
