I am assuming that your solely relying on the trucks computer to calculate your mileage? Try to do the hand calulation and you may find out that your about 1.2 - 1.8 mpg lower. Not trying to bust your great mileage but these trucks never tell the truth. Just pretend that you are on top of a hill and going down on a 7% grade for 2 miles - you will most likely get about 99 mpg per the computer. Just saying that the computer is not accurate.
I'm like the rest.. I was recording the actual fill ups for awhile and found the comp is only .1 or .2 off of the pumps gallons and hand calculating is just in tenths difference of mpg..
I'm not bothering to record anymore, because I'm satisfied enough to just go with the comp as it's just close enough more me.. :)
Yes, if you reset your instant mpg going down hill, it'll show a pretty high mpg reading... ;)
