[QUOTE="JRLott, post: 1347206, member: 19991"] I have never observed ANYONE getting what they claimed...except me, though I hand calc every tank. Those that were in line with my figures get a pass. Everyone barely above does too. That could be driving styles. Those 1-5mpg above me get a that's great, but I don't believe them until I witness it...calculated. 11-14 SDs are a bit different, too many people I trust are getting better mileage than the 15s for it to be a fluke. I think the 15+ trucks run better...they just don't get quite the mileage. [/QUOTE]
