Totally stock I WAS getting low 18s hand calc. This was when the truck was new and I was driving like grandma ma on valium. Now I get 11-12 around town and 15-16 on the highway. I am gonna take a 3000 mile trip in mid May to Montana. I will do all my milage calcs. with a gps. Your figures are only as good as your speedometer is accurate, so i will use gps which is probably more accurate than the speedo. I will report milage and prices when I get back.
PS this truck still does much better mpg than my 460 one ton ford. What a pig that thing was.
