Dude so do I. I drove like a grandma on my last tank and even drove almost half highway. I thought I was on my way to a 400 mi tank...nope. Just before 300 the needle went woosh right down to where it normally is and I managed to get 2mpg more than I do when I beat on it. Oh well.. I saved 2.50. Not worth feeling like im getting passed by a schoolbus.
