So I was driving the truck and realized I need gas. Partly because the little light that says "Holy shit man, I need a refill!" came on. Normally I don't let it go below a half tank but I've been driving a lot lately for work. Now my question is, I have the 5.9L Magnum engine in my Dakota. Would it be better to use Premium gas or should I just stick with the 20 cents a gallon less Regular?

Edit: I guess I should have mentioned that the 2000 Dodge Dakota was never offered (so far as I've been able to tell) with a manual and a 5.9L Magnum. That's why I'm asking.
