fordguy7 do not worry about the v-10! i am on my 3rd one the older v-10 gives u better fuel milage[99 to 04]. im currently employed to haul rvs to all parts of the country and i can tell u right now the deziels are over rated and over priced! dezeisl r soppose to not break well guess what they r breaking. fuel injectors seems to be the mane issue [very exspenve]. now the ford desiel is 6000 dollar option the v-10 is 600 0ption. at 70 mph with 4;30 f-350 6 spd man. i can get 15 mpg. my other v-10 i can get 16 mpg onley diff. between the two f-250 has 4;10. f-250 06. f-350 05. [new v-10s]the ford desiels are averaging 18 mpg. now u sit at the table and do the math and u relieze that desiels r not worth it. my f-350 is my work truck. i have 60 thousand plus and going to find out how far this 10 will go. ive been hering big milage numbers coming out of the gas engines. towing wise u r looking at 8 to 10 mpg at 65 mph depending what u r towing. at 60 add a mile or two. the 01 i had f-250 5 spd man 3;73 got 18 mpg. as for the automatics in older ones averaged about 15 mpg[highway].i dont no what the new 10s r doing i havent talked to anybody that has automatis. my guess not as good. so there u have it im planning posting at 100,000 to give more details on the v-10. one more thing to point out the 99s they had issues with them with catlac conv.and not as powerful as the other later years. there is guy said he herd that they had crank problems but i havent talked to anbody that run into with that issue [and i talked to a lot v-10 0wners]. my guess on this is keep the revs down and i dont think there is just a handful with this problem[if any]. later

Snowtoad: Thanks for input. I agree about diesel and already ruled it out. Decision is new V-8 w/ 4.10 vs. V-10 w/ 4.10 gas. Current 2000 F-250 w/ 4WD 5-4L V-8 gas 4.10 axle auto tranny getting 10-11 mpg around town, 7 mpg pulling 32' 9000# Prowler at 65 mph. Pulls OK, but getting old, mileage getting worse, a little slow from stop position, and I'm only towing in flat Fla. Concerned about performance if I towing outside Fla. Would jump at the extra muscle and giddy-up of V-10 for only $600, but they only make w/ 4.10 or 4.30 axle and I worry day-to-day mileage (while not towing) will be drastically worse than 10 - 11 mpg I get now. I'm getting feeling from you it won't be, and may possibly be better with new rig. If you or others have any additional input, would like to hear from you. Thanks!

Ford 2008 F250 Fuel Mileage by flashover6

I have a 2008 F250 W/ 6.4 Liter Diesel. As of yet I have not gotten better than 11.8 mpg. This was w/ no load and on the highway. I am very dissapointed with this. I drove my fathers 2001 F250 w/ 7.3 liter recently and got 17 mpg.

A follow up to my post #63 above RE: 2008 F-250 6.4L Diesel Crew Cab . Been hauling my 7,000 lbs travel trailer these past two weeks from Boston to Wyoming (3,000 miles) and I am only averaging 7 MPG at 70 to 75 MPH w AC on. While this is a major disappointment, the truck is a moose and pulls steady and strong. I really like the truck otherwise. I hope this mileage improves over time, but I am not optimistic given what folks are saying in this blog. Interestingly, I have only seen one other 2008 F-250 6.4L Diesel since I have been on the road. Is this because smart shoppers aren't buying them?

2008 F-350 Mileage Complaints and Axle Ratios by dadzpony
Aug 03, 2007 (7:48 am)

I'm about to order a dually/diesel. I have read the concerns about mileage and am disappointed but...I need a truck like this. No one mentions axle ratios. Beyond the obvious that 3.73's SHOULD GET better mileage than 4.30's is it a mistake to order a 3.73 vs. a 4.10? Are people with 6mpg driving 4.30 trucks? is the 12mpg guy driving 3.73?
The ratings are the same at 15,200. Is a 3.73 a looser in resale or towing? I'm towing a Goose Horse trailer 10-12,000 lbs.
Thanx...

you are getting some of the best results. You didn't mention if your diesel or gas, and what is your axle ratio?

diesel and axle is 3.73. 11.5 mph pulling load, 13.5 in town and probably 15 on highway. I have a trip computer which is not always accurate and sometimes confusing and shows an average of 13.4 most of the time, but you have to do the real math.
