    I just installed 2inc icon lift w/ LT285 70 R17's, with wheels and an exhaust. Everything was great until I noticed the gas gauge dropping....Is it normal to lose between 5 and 6 MPG with these modifications? I expected a little, but damn. I have a 2009 Off Road, V6 double cab.

    Thanks

    lift, larger tires, winter gas blah blah will reduce your mileage most definetly. less aero dynamic, more friction to the road makes for more pedal usage

    Did you take into account the tire size screwing with your odometer?

    I went from 19-20mpg average to 16-17mph avg when I did the same lift and tires. IIRC is a 7% difference between stock and 33s.

    I go off my scangauge for the odometer. It is set to my GPS for the speed. Even then, its never off my more than a mile or so.
