    My '10 Tacoma is getting lousy gas mileage (~16)...I check the air pressure in my tires weekly and I keep my foot "out of it" however, I am still having no luck! I have been looking on line and have pondered the following modification and was wanting some advice:

    1. Install a Cold Air Intake
    2. Computer Chip Jet Programmer
    3. Install dual exhaust

    Has anyone out there tried any of these? Any luck? Thanks!

    How many miles are on it? On my 09 I started out averaging 16-17 mpg. With it breaking in around 5-6k, and loosening up I am now up to 18.5-19 mpg avg.

    As for the 3 above, the only one that has much of a chance IMO is a CAI, but that is debatable. My experience is that a CAI does nothing but make noise, same with exhaust (which may also decrease mpg as it might cause some loss of low-end torque, in exchange for high-end breathing). That is my experience though. Don't even consider 2.

    Might try a drop-in filter like an AFe Pro-Dry S. K&N could also be considered, but it's not my first choice.

    For my mpg's, I can always equate what I get to my driving mix (city/highway), style (jack-rabbit vs. a bit easier) and AC usage.

    CAI will lose MPG. I've had multiple CAIs and this has always been the case, I currently run a AFE drop in and found that its the best solution.

    Try disabling the compressor mod when defrost is on...that saves drag on motor.

    Run the tires hard, with syn oil and try and keep it at the speed limit and get a scan guage to monitor your instant mpg..finding the sweet spot on your drive. Other than that yes these trucks suck at mpg.

    What are your specs? Stock tires, lifted or other accessories that might add weight.
    It has been stated on here several times CAI actual hurt your mileage. It is better to keep the stock intake and swap the factory filter for a high flow.

    See build thread.
    my 2010 double cab 4x4 had a sticker that came on the window that said it would get 16 in the city and 20 on the highway. yours being a prerunner probably said you'd be getting 17/21.

    with a mild lift and bigger tires i am getting about 17.5 with winter blend fuel in the city.

    You might want to consider getting a Scangauge II. After you calibrate it, it will show you instantaneous gas mileage, average over the trip and average over the tank among other things such as distance until empty, error codes for the check engine light, etc. This wont change anything about the vehicle to get you better gas mileage but it will make you more aware of your gas mileage which will in turn train you to drive more efficiently.

    I originally was getting 15 mpg but then again I have it lifted with some BF AT's. I did install a CAI and started using 92 high octane and have been able to get 17 mpg. It's not great but hey, it'll do.

    16 MPG sounds pretty normal to me. I'm averaging 16 in cold weather while burning winter-blend gas. I expect l'll average closer to 19
    in the warmer months. See banner below:

    i put a K&N cold air intake on my tacoma and it gave me about 3 more mpg and more horsepower and it was super easy to put on

    I've found that premium grade gas made the biggest difference for me... With the price difference, you're really robbing Peter to pay Paul.... Also, keep track of you're trip per tank, then try different suppliers... I know that in my case, some brands of gas just get poor mileage compared to others.

    I dont know how you guys are seing 17 + in the city... My best is 16.1 in the summer and with winter I am now avg 15.2. I guess maybe because I live in the mountains. Highway, I can see around 19.5 to 20 though.

    PS.. 42 k on the truck and the plugs and everything was just changed.
