Well im looking at a 99 f250 it has the 5.4l in it. But it has 169,000 miles. How reliable are these with high miles? Any major problems when we get up there in the miles?

Also, anyone know around what mpg they get?

 

I have seen them get well over 200000 miles. It is the older style 2 v engine, It should get around 12 or so depending on how heavy your foot is. If it is clean, when running take off the oil fill cap see how much white smoke (blowby) is comeing out... Less is best.

a couple guys had over 3 pushing 400,000 on theres.
I like the 5.4 liter. I wasnt sold at first but I am happy with my 3v 5.4

If your gonna tow make sure it has 4:10s

 

how do u check what gears it has?

 

One easy way (don't have to crawl under the truck) is to look for the axle code on the data plate on your driver-side door facing. While you're at it, write down any other info you might need later, such as tranny code. I keyed my data into a "word" document to save trips out to the truck, but as the fancy folks say, I digress. Next, do a Google search, or a FTE sear for Ford differential codes, and that ought to get you several sources. Most late models are two characters, such as H9 , which is 3.55.

 

I owned a "99" and now have a 05, which has 3 valves. My '99 had a 4.10 and I used it to pull a 38' camper all over the easten U.S. It did great but I wouldn,t want to be the 2nd owner if you get my drift. It had about 220,000 on it and never need oil added. My towing mpg was 9-10, and non towing was 16 usually. City mpg was 12-14. So, you are looking at a truck that has the potential to give many miles of good reliable sevice or need a motor, tranny, diff., depending on how it's been treated. If it is tight and clean, runs very strong and quiet, and drives good, and maybe most of all isn't rusty, be my guest. A 169000 mile F250 should be tight cuz Ford built it tough.
