    '13 Tacoma Sport on the way
    Just bought a brand spankin new 2013 Tacoma Sport access cab with a manual 6spd trans. Completely new and stock. I have about 180 miles on the truck and so far and I barely squeezed 150 miles out of half a tank. Roughly speaking, that's about 7 miles per gallon with reading that our 2013's have a 21 gallon tank.

    I have been shifting around 2k RPM, and really babying the clutch and revs. On the highway, I drive 60-65mph max and try not to accelerate/brake, accelerate/brake a lot.

    My plan was to baby the throttle and see what I could get out of my first tank of gas...and right now, it really sucks.

    I was really not expecting this. This is my first truck and I wasn't expecting to get great mpg, but at the minimum thought like 15mpg for driving like a grandma. Anyone have any advice about this?? I can't imagine if I started revving up to 3-4k and driving a little bit more aggressively...what then, 5mpg!?

    thats about 15 mpg to my math..

    20 gallon tank, 150 for a half tank.

    half tank = 10 gal

    150*2= 300
    300/20 = 15 mpg

    Welcome to Beater-ville!
    The fuel gauge isn't perfect. I have a huge first quarter of the tank, small 2nd and 3rd quarter, and decent size last quarter of the tank.

    Tank wasn't completely full when you got it, engine not broken in yet, and old gas in it from dealer could also be contributing. Burn off that tank and fill with fresh gas, then start checking your mileage.

    Not really sure if you doing your math right :notsure:

    21/2= 10.5 half a tank

    150/10.5=14.285714 MPG for a half a tank

    same shit as everyone else
    Low RPM's doesn't always mean its a leaner fuel mixture and better milage.

    I'm guessing you did:

    150/21=7.1428571

    Well...if 1 person would have commented and I caught my mathematical brain fart, I would have edited my first post. But now I'll just leave it haha.

    Anyway, I had to take a little highway trip tonight to pick up a new shotgun and drove about 85miles on a quarter tank. That's about 17mpg which is pretty good for highway driving at ~65mph.

    I'm going to burn off this tank and start calculating each full tank from here on out, just to see what I'm working with.

    im not sure of where you live/how any hills, temperature there, etc, but on my last two road trips ( all in florida and on flat interstates, etc) doing between 75-80 i pulled off 20-21 mpg both times. with 245s though. :(

    Hey Tacomaworld this is my first post and I love my tacoma.

    This is what i what i do. Fill my tank to full, drive until the lights comes on. refuel and it shows +/- 17.1. The tank is 21.1 gallon so there still fuel in the tank 4 gallon or so. I usually get 328 miles/17.1 gallon of fuel which is 19.1 mpg. Running on 91 octane that what I prefer. Tacoma pretty good on gas if your dare to drive with the fuel light on. When the fuel light turns on I drove additional 40 miles from Orange County to Los Angeles. With spare 1 gal of fuel on board.

    CEFishin already mentioned it but I was going to say the gauge isn't very accurate. You usually still have 3-4 gallons left in the tank once you reach empty.

    I agree with this here. Your fuel gauge is not linear in any way, shape, or form. You can't go by that. The gauge is really just meant as an estimator for when you are due to fill up again. The only way to accurately calculate fuel MPG is as mentioned: Start with a full tank, drive a designated distance (the longer the drive the more accurate your calculations, so I suggest 150 miles) Then fill up and divide the number of miles by how much fuel, and bingo!

    Drive slowly the 1st 1k miles to break-in.
    Change your oil to synthetic.
    Then use trip mileage function on truck, divide trip miles/amount of gas purchased @ pump.
    Allowing the truck to break in, & performing a "real" calculation will provide a more accurate MPG for your truck.
    After saying all that dont expect too much MPG from you Taco.
