    Anyone driving a 2009 or 2010 Ford F150 with the 4.6L 3 valve V8 engine? If so, what fuel mileage are you getting?

    Yep i have a 2009 4x4 with the 4.6l 3v. We took a trip to North carolina and averaged 21.6 MPG. In town is averaging right around 15. I Absolutely love the engine and the truck.

    I have a 2009 2wd 4.6 3vavle 8ft bed and man its a ballsy truck for a 1/2 ton and being the small block v8... I avg intown + highway going to school and home to my dads and back I avg roughly 80-90 miles aday @ 15.2 mpg. I set that avg mpg on the dash soon as I got the truck so I've had the truck maybe 5-6months have 14k on it bought it with I believe 52 miles and man it is great... you can search in the picture thread to see my setup and my truck... haul around 3500lbs with it during the mowing season and get about 14mpg maybe better... trailer is almost 2k by itself

    I am getting 15.2 mpg around town with my 2009 F-150 4x4 4.6 3v. I have only put 2,500 miles on it so far and not much highway driving. I got 15mpg on a 100 mile trip towing 2 ztr on a 6x12 trailer doing 70mph on the highway.

    What's your rear axle ratio?

    I'm interested to know the mileage as well, in crew cab 6.5' box guise (2wd) the 3.55 axle is the highest available (in Canada at least on the crew cab XLT). Does the transmission hunt for gears while towing, or is it somewhat smart and hold gears with minimal shifting?

    I test drove an '08 with the 4 speed 248hp 4.6L at the dealer and I didn't like it. Perhaps if this new 6 speed doesn't perpetually want to get into 6th gear after 50 feet of taking off from a stop, it should be a worthy vehicle, even with the 3.55 axle.

    21.6 Thats what my more aerodynamic mustang with a 5 speed gets on the highway. You must be going less then 70.

    My '91 LX 5.0 fastback got an average of 22mpg, but it rarely saw above 65mph on the highway. I had a 3.73 axle installed when I inherited it.

    No we averaged 75 mph. some areas got to 70. New vehicles are getting much more efficient day in and day out. As well as improving their aerodynamics.

    Its got the 3:55's. every now and then it will down shift a little more then id like...But all in all, it does a good job. The max it will ever pull is 4k, and it handles it fine. Mine also is getting about 15 in own as well. I really am loving this truck more and more. It definitely doesnt hunt at all. It knows where to be and stays there until it doesnt need to be. I can tell it is very smart. I love the tranny. It reminds me of the torqshift. In tow/haul mode, its got a great brake in it. slows the truck all the way down without you touching the pedal.

    Good to know, thanks. I built one online with the LSD 3.55. limited slip can't be had on the 3.31 gears, which seems VERY LOW, especially with the 6 speed. I'm glad that Ford programmed the tranny right!
