ok, so I just got this truck a week ago and filled it up full after an air filter, oil filter and fuel filter change...I went last night to fill it up again as I am heading camping this weekend and the miles I had driven last week were 158.6 and I filled it up at a little over 16 gallons last night. Does this sound right? only getting less than 10MPG. most of the driving has been around town with little to no freeway, and it is running 285 75 16 tires. I believe it has 3.73 gears, but I am not sure. When i brought it home it had a hell of a diesel leak out of the petcock, that was fixed i thought until this morning I notice a small silver dollar sized drip on the concrete under the truck. It looks like oil, but really didnt have time to look at it since I was on my way to work. What is a realistic fuel milage for this truck? Also, what are some of the things I can check out to be the problem. BTW I am comparing this to my 2003 Duramax that would get about 22-24 highway.
