    Just have a quick question for you all. We are in need of another truck, nothing big or fancy. Just looking at some 2010 f 150s. Need to know if a 4.6 will do me light duty or if I def. need a 5.4. Thanks in advance!

    Plowing or towing? If it's just a daily driver, hauling around a few tools or whatnot, the 4.6 will be just fine and get decent fuel economy. In terms of reliability, you cant really go wrong with either motor. If it's going to be plowing or towing, get the 5.4, no question.

    Well I was actually looking at an 05 f250 with a 5.4 in it...Turned away thinking the gas would be horrible.

    I rather go with 5.4L

    I get 22 mpg out 07 Lincoln LT I know it tough but set at 50 mph with cruise control for 200 miles. When you go faster and mpg go down fast.

    70 mph= 16 mpg 50-55 mph= 20-23 mpg.


    4.6L can do but would work hard struggle carry weigh and tow.

    Also I believe they only sell the 6R Transmission with the 5.4. You still get the 4R with the 4.6. If the truck is doing any sort of plowing, hauling or towing, you should get the 5.4.

    I have a 5.4 in my f250 and it tows and plows great. I looked at a few f150 with the 4.6 and didnt think it was enough motor for the big truck.

    well whats the thoughts on the 05 250 with a 5.4, is it worth it,...Right now as I site my options are:
    05 f-250 75k 5.4 for 22,000
    2010 f-250 xl with xlt decor package(so it doesnt have the sealed beam headlamps)32,000

    I had good luck with my 4.6. 19 - 22 mpg, hauled a mini excavator thru the Pocono's with no problem at all. If given the chance again, I would go with the 5.4. I didn't plow with mine as it was in a 06 F-150 Crew Cab. I think the 4.6 holds its own very well when it comes to towing and daily driving, but it would be nice to have that extra ump when plowing.

    I forgot about the 4.6 3V as an option. That engine with the 6R may not be a bad option.

    The 4.6 2V is a complete dog.

    I own a 4.6 in my 150, 2009. My buddy plows with that set up in an '08. It works. But if I were weighing an '05 vs. '10 and both fit my budget, I would go with the '10. Warranties are comfortable and so is knowing a maintenance record/how its been driven. You're comparing 3/4 tons though....
