On a similar topic, with all the diesel cars coming to market now I'm seeing our local fuel service stations (I use WaWa) have changed their pumps over to both fuels. What I mean is at every pumping island there is a choice for diesel or gasoline. It's up to you to press the correct fuel button and hose. Here in Jersey diesel is self serve but gasoline is not. I'm sure there will be a rise in folks fueling up their diesel cars with gasoline. I see them busy talking and texting on their devices. One day they will come out with a nozzle that only fits gasoline and one that only fits diesel.
