    I have a 2005 F150 2 wheel drive with a v8 . I calculated my gas mileage today and came up 12 miles per gallon. Does that sound right? It sounds way too low to me.

    I bet it's not far off. You filled the tank, drove x number of miles and when you filled the tank again with y gallons you let it auto shut off both times and didn't put any extra in either time? What were the numbers?

    Completely plausible on winter gas, especially if you were doing very much in town driving at all. Even if it was all highway, driving at speeds over 70ish mph will make that number go down in a hurry.

    Completely plausible. Now get your foot out of the pedal when you take off and you will get around 16-18

    Depends on what kind of driving you do. I get 13 mpg in around town driving on my V-8 Merc Mountaineer and 19 on highway. As opposed to 24-36 on my Sonata.

    Seems low with a gas engine and 1/2 ton.

    For the year my 2006 F250 Diesel did 13.8 mpg. This includes thousands of miles pulling trailer, 70-80mph interstate and everything between. It weighs in at 9200 pounds also.

    F150's should be around 13-16?

    Not in stop and go in town driving but YMMV.

    I always get worse gas mileage during the winter months due to the 10% ethanol mix that's at the pumps around here this time of year

    I believe that this is your answer. Different vehicles, same numbers.

    My '91 F-150 can get 17ish mpg when I cruise around easy even when I'm hauling around a 500 lb load. When I had to drive it daily to work and make sure I got there on time, I could only manage 14.5 and that's just 70-75 on the interstate with little stop and go driving.

    My Explorer is only rated at 23 highway and 19 combined yet I've averaged over 30 on a highway trip and 29.5 combined before but that took careful acceleration, coasting to stops, max pressure tire inflation, and nothing over 60-65 mph. I've managed over 19 mpg in an F-350 4 dr. 4x4 dually with a 7.3L while the truck's owner can only manage 12 mpg. I would expect better than 12 myself out of your truck. However, knowing how much mileage can vary due to driver input, it's hard to say what's low without knowing how you drive, tire pressures, and running condition.

    Keeping a close eye on mileage, I've learned that merely starting up in the mornings, in and out of the garage, and my driveway costs me a mpg over the course of a tank. Warmups are even worse along with what firefighter4215 said, I've never hit peak mileages out of any of my vehicles in the winter. I routinely got 32-33 out of a 4 cyl Mustang during the summer but only managed 30 when it got cold.

    So does it sound low? Sure. Way too low? No. The last 150 supercrew 4x4 that I read a long term test about was averaging 14.xx mpg. That's about the same as what I've heard from others with F-150s similar to yours with one exception. A coworker that lives in Hampton, VA only got 10 mpg out of his '04 and the truck was in great condition when he sold it.

    What gears do you have in the rear? I've got 4.10s in my 3/4 ton Dodge V8 and I average just under 12 mpg for mainly highway (not interstate) driving.

    Also cold air will use more fuel. Cold air is denser so more fuel needs to be mixed with it in the cylinders to get the proper combustion and commanded air/fuel ratio.

    So usually in the winter, with the reformulated gas and colder weather it's not unusual to see a few mpg less than you would normally get.

    I usually get a city/hwy average of about 16-17mpg with my 5.3l Yukon, but in the winter months I only get 12-13mpg average. It goes back up come spring.

    Ethanol is going to be the death of comfortable trucks and small engines everywhere. I hate winter blends. I add a quart of 2 stroke oil to every tank of diesel in my Dodge, still averaging about 23.

    Sounds about right.

    And don't feel bad, my '99 Dodge Ram 1500 4X4 5.9L gets a solid 10. City or highway. Doesn't matter. I *might* get 11 if all my driving is downhill in neutral with a tail wind and the engine shut off.

    It's the main reason I'm trying to get my bike back on the road. 55MPG vs 10.

    My 2000 Ford Ranger 4x4 w/ 3.slow V-6, auto and 4.10:1 gears, gets 14-16 mpg around town.
    (And this is staying around 35-45 mph!)

    It gets 16 mpg highway, as long as I stay at 60 mph or below.

    65 mph. . . . I can watch the gas gauge go towards empty.

    This has more to do with gas mileage than most people realize.
    If its geared for pulling than 12 is what your going to get with a truck that age. Swapping gears would change most trucks from 12 to 17 on average.

    I have an 02 f150 4x4 (2v 5.4). Highest mpg I've gotten is 12.5. Pure in town gets me 10-11. Going to try changing plugs and upstream o2 sensors when I get my taxes back.

    Yours does seem a little low for being 2wd with the 3v. All your maintenance taken care of? Do you have a heavy foot?

    No, maintenance could be better.


    As far as a heavy foot, I was very careful during this test to accelerate very slowly and I didn't drive over 60 mph. 70 is usually normal for me.

    This truck is the sporty short bed with an extra cab. I doubt it has towing gears.

    Probably not. 3.55 or 3.73 is what most come with. Try filling at a different station and take a look at the f150 forums for tips.
