    Fuel economy expert David Rizzo discusses if you should continue pumping after the automatic shut off.

    Host: Should I continue pumping after the automatic shut off? David Rizzo: No way and this is a big no. For one thing it's dangerous and this is one of the reasons why you don't want to be on fast, because if is on fast, once it gets full, I have seen it where you pull the nozzle out and the liquid gas spurts out. All of sudden it's on your paint job, it's on the ground and it's a fire hazard of course. So, you definitely want to stop on that first click. The other reason is if you keep trying to force it in, again now you are pumping in vapors. There is a lot of turbulence. The back pressure from your tank is forcing vapors right out past the nozzle. You are doing nothing but wasting gas by keep going after that first click. In other words when that handle says shut off, leave it at that. Don't try and squeeze in an extra gallon or two. It's just wasted.
