OT 08 ford f 150 crew cab question

Hi all,I have a chance to buy a 2008 ford f150 4 door, 5.4 triton, 6.5' box with 25,000 miles on it. The seller is getting a 2011 truck. It has 3.73 gears in it and i would rather have the 3.55 gear ratio for gas mileage. Window sticker says 17 highway. Will it make 17 really or isn't it that big of a deal on gear ratio? I wonder what mileage a 3.55 truck would get for mileage. I think it is priced right.I wont be pulling anything, It will be used for light hauling and like a car. Thanks

Isn't the Triton Engine the one that launches sparkplugs ? Theres only 3 threads in the head to tighten against.

Well for my take on MPG by the vehicle manufacturers,Most are tested in a lab under controlled conditions,with the very best lawyers taking all the info and adding their style to the "definition what "is" is".All manufacturers are in fact the best liars for mpg ratings,and trying to prove that they are wrong, it"s easier to prove the world is flat.Now with that being said,take 2 vehicles,being same gears,transmissions,but put in two different drivers, gauranteed you"ll get two different mpg ratings.For the most part even with 3.73 gears,you can change tire size,to get down to 3.55 gear ratio,but the trade off is having to get the transmission recalibrated,and if ever you change back to original size tires, have to recalibrate the tranny again,unless you buy a aftermarket controller for it and every time you change tire sizes,you can change the tranny codes.All require xtra cost,but more flexibility.Some of the aftermarket controllers let you adjust the performance to your needs,but only to a certain extent.So with that in mind, I would say you would gain maybe 1-2 mpg difference between the two ratio"s,but just my opinion,not factually tested and proved.LOL

Yes is was another one of fords stupid deals.

I have to ask this question.

Why is this guy selling a 2 year old truck with only 25k miles on it.? WTF?

Is it a Lemon?
Or is he rolling in money and really really wants another New truck?

Get it checked out real good before you buy it.

Real mpg from real driving.

Yes probably the most popular engine on the planet, with the least recalls.

Ever drive one? Not exacgtly a 'powerhouse'. I'd suspect that's the reason for the 3:73s too. :>)

I had a 2000 with the 5.4 and I drive it to work and back each day for a couple of years. It is 25 miles each way of paved roads, and I averaged 16 mpg consistently with it.

No, this is the one that has the two piece spark plugs that break off and leave the bottom of the plug stuck very tight in the head.

I have the 5.4 in an 03 f150, plenty of power there i think, the 4.6 is the gutless pos with no power, I've pulled several tractors with mine and didnt even know they were back there, the latest was a MM UTS, pulled it on a trailer through the woods, up and down hills, seemed to do great, other than no trailer brakes it did a great job...Bob

Plug spitter unless Ford changed. Plug change at dealer by me is 4 to 700 and more if they break any. I have 2000 with 113K miles. Decided to run it until starts missing or I think of something easier. Son had this truck too so we have been there and done that. Dave

I have the same truck. 2008, F-150, Crew Cab, 6.5ft bed, 3.73 gears, 5.4L . Mine is the White sand with tan leather. Bought it new, now has 31, 000 miles.

It will get a solid 16.5mpg on the interstate ( if you drive it 70 mph or less) 15mpg mixed driving (if you take it easy) and 13 mpg in town, and 10mpg or so if I pull the car hauler with the Ford 641 on it or a good load of wood. So will it make 17mpg... maybe but you will have to be on the interstate and drive like an old woman. In 2009 the EPA updated the fuel mileage on all vehicles and the true version of that is more like 11 city and 15 highway. I just looked at my window sticker and it says 13 city and 17 highway, but in small print it says city will range from 10-16 and highway will be 14-20. The above numbers are real world using 10% ethanol blend gas from BP which is the best I can get here. Cheaper gas will get worse mileage.

If you get it get a set or Weather Tech floor mats for the front and back as well as a set of long add-a-leaf springs as it will not haul much without them.

The plugs are a two piece which may break off in the head upon removal, but you can buy a tool to remove them ($80). The ones made in November and later on of 2008 have the plug problem fixed. Check the drivers side valve cover for the date.

You can get the 3.55 gears but it will be weak off the line and get 0.5 mpg more. Ask anything else and I will try to help.

We bought a Ford Focus (27mpg) to save on fuel.

I put about 65,000 on one just like that . Was an o8 I don,t know anything about the plug thing I always drive them two years and trade. Mine would read 17.1 on the dash running 76 mile a day to work on 4 lane. Drove 4 thousand or so last fall out west . Pretty hard driving Nebraska wind one day was high and run hard. By fill up from the time I left home to return got 17.4 mpg I will say anything more than an engine heard ( 200) lb in the back end and the shift points change. They have got that power trainto the max.. Driving a 2010 now that is quite a bit more driver friedly but no better gas milage. Ford had me drive a 11 for a few days last month has a v 6 with more power than the current v8. Think I will wait till my normal trade to make that decesion. Now that I am retired I am thinking 20,000 a year may catch it.

We bought an 07 with a few miles on it... had it for more than 3 years now... great truck. Very comfortable on the road... great power and reasonable mileage. It's my wifes truck, but when I drive it, I put on 30 or so miles a day (mostly hiway) she runs back & forth to work in it mostly... around town, we get 14 - 16 mpg... on our road trips, we average 22 mpg. One of the nicest, most reliable vehicles I've ever owned. In reference to the other post, Ford did fix the problem with the heads... I think the key to avoiding problems with sparkplugs is to change them before 100,000 miles. Our truck has just over 50K on it and I plan to change them soon.

I have an 06 F-150 with the 5.4 and 4.10 rear end. highway mileage runs 16 to 16.5 mpg empty, but it is rarely empty, so mine varies a lot. Higher rear ends will not matter a lot, because according to some of the Ford sites I used to visit, the low rpm torque of the 5.4 is not very good, and I have noticed when pulling loaded trailers that my gas mileage is best once engine reaches 2100 to 2200 rpm.

As to the spark plug seizing problem, I believe that was solved in 2005 by a modification to the heads and the use of antiseize

I own an '06 F250,ext. cab.5.4. 4WD.6 spd. manual. 3.73 gears and get a solid 17 MPG on the interstate at a steady 70 MPH. Localy 15-16.

You will love that truck!!
