    Hey guys so i checked my mpg on a trip to Arizona. Each time i filled up the tank i was getting 12.5 miles per gallon!!!! This is horrible for all highway going 75? I do have a 4x4 with 3 inch lift and 33s, but i would think i should at least get 15mpg? Any input??



    HELP MEEEE

    You're driving a lifted truck at near 80MPH. Not exactly aerodymanic. MT tires are the greatest for MPG neither.

    Try keeping your RPMs under 2K while driving. Really improves the MPG.

    Mines the same bro 3" lift with 33's and i made a trip home to colorado and got 13 mpg! HORRIBLE... I did notice that if I didnt use cruise control I could control the rpms more keeping it in a higher gear. Not really sure if it helped but it made me feel better driving at lower rpm's. Ill sacrafice mpg's tho cuz I love the way my truck looks with 3" and 33's :D

    1. don't forget to adjust your calculations for the increased tire size...10 miles on 33s really isn't 10, it's more like 11 miles traveled so 12.5 mpg is really 13.75 mpg (roughly) unless you got your speedo recalibrated
    2. anything >70mph will start to kill your mpgs for sure..lifted truck with tall wide tires = mpg killer

    I gained 2-3 MPGs just by keeping my truck under 70 at all times on the Highway. I have noticed that if I stay in the left lane, I feel like I am trying to keep up or stay ahead of the person behind me. If I stay in one of the middle lanes, I can stay more consistent with my speeds. In your case, if the Speed Limit is 75 MPH, don't go over 75. Choose the lane that will let you be the most consistent with the skinny pedal.


    Also keeping the RPMs down, by choosing the highest gear for the speed.

    3" lift headlight mod.. indash dvd player with backup camera ... overhead sirius radio... HHO... scangauge2... vent visors... TRD seat covers... mounted streamlight in console... window tint... bed cover... K&N air filter... Tires and Rim upgrade... USB plug in behind console... bug shield... Upgraded all speakers in truck and installed two subs and amp behind rear seat
    if you didn't reprogram the ecm for the bigger tires then your fill up mileage will be off... I went from 245/75/16 to 265/70/17 every 100 miles my mileage was off almost 6 mpg. even on my scan gauge 2 but, here's the kicker... ( before the lift and tires... my gps was showing 2 mph faster then my speed-0 on the truck.. pretty much all cars and trucks are programmed that way..) after reprogramming the ecm my mileage went back up. I have reprogramed my computers in my taco 4 times..

    I use E rated 33" KM2 mud terrains and I never get under 16 on the highway. If long flat road, I'll get 18 in a no-wind kind of day.

    Which was surprising given I have a roof rack I can't fold away, and a big ARB bumper.

    The skinny 10 inch tires probably help though.

    This is calibrated mileage from the scangauge.
