Well I just got my truck a week ago and when I left the dealership they filled it up and I already had to fill it up yesterday. I only live about 10 miles from work but after work I mow lawns also so I am always pulling my 6x12 enclosed trailer and I think I am only getting like 9 to 10 mpg the overhead said 210 after I filled up this weekend but I have been keeping my foot in havent got used to the exhaust sound yet. LOL
