Yeah but isnt your miles off because of the gears and tires, or do you have something to correct it

 

im glad this thread was on the first page, otherwise i was about to post, that yesterday, i got an incredible 13.24 mpg with my truck 296.1 miles....ive never come even close to that before. more like 225-30 miles and 11 or so mpg. 91 octane and ran smooth and pulled noticeably harder for some reason.....hope it doesnt stop!!
