Newbie question: Flying J pump menu

This is kind of off the subject. but I will tell on myself here. Every green pump handle I had ever seen before this happened was diesel. I'm from Oklahoma, but even in other states it was that way. Got in a hurry one time in Pa., pulled up to a green handle, filled up, went about a mile and guess what....I had filled up a Dodge diesel with premium unleaded. Didn't run too well on it. No permanent damage to the engine luckily. Anyway, sorry for the long story, but maybe it will save some one else from doing something like that! Always make sure you have the right fuel going in to your vehicle!:o
