My 6.4 R/S is a 08 F250 4x4 crewcab shortbed with 3.73 rear gears. Now with 5000 miles on the truck ,Im getting 14mpg around town. The only highway trip was towing my 27ft 7000# travel trailer and averaged 10mpg.

Hopefully this hasn't been posted yet. But here is a dyno video I came across of the 2008 Super Duty 6.4L Power Stroke Diesel.
 
It's at the bottom of this *Outlaw Power* Intake System page.

Power and torque look very nice. This engine seems quiet, a good thing. Let's just hope Ford can keep that production line moving.

I picked up a 08-f250 Super duty with a 5.4 gas for the wife this Weekend.
I’m looking for a cold air kit and a cat back system, any ideas??
Any one have an aprox. MPG rating on this truck?
I’m new to your Forum and was reading some of the post they had great input.
Thanks

5.4 mpg. by mschmal

depending on whether you have the 3.73 or the 4.10 rear end, your MPG should be in the midteens to 18 mpgs when you break it in.
 
I recently dove a Navigator L with the 5.4 about 30 miles mixed highway and city and got 17 according to the computer. This was a new truck with the 6 speed trans and I was very conservative driving it.
 
IT is all about how you drive, and how fast you go.
 
The size of these vehicles exagerates the affect of hard acceleration and going over 65 mph vs. a car.

Thank you.
I have the 4.10 rear gears, with the 5 speed auto trans.
The wife loves it, it only has a 1,000 mile on it and we got 15 MPG on a short trip this week end doing 75 with the air on.
Thanks again for your input.

I have 4 of these 2008 f 350's and these are the worst purchase I have EVER made.
if yours isnt giving you problems wait till you give it some work.
Out of 4 ,3 have been down muti times 2 have had the motors replaced 3 have run hot due to faulty raditors.
Only 3 MONTHS OLD.
Fuel milage yea put a trailer behind it you will get 5-6 miles per gallon unless your driving 50.
I am looking for others like me who have had serous issues with these to work a lawsuit up to collect damages and lost wages due to all the down time with these lemons.
If you have had any kind of probelm please email me at wackiinYahoo.com.
If your not having issues I wish you the best you better leave it sitting in yard.
