Hi Guys,

Have a 08 Ford F 350 Super Duty 6.4 diesel 36,000 mi. Would like better gas mileage. I get 17- 18 on the road with a light throttle. Any ideas on how to increase mileage. I am selling my 5 th wheel so power is not a problem. To replace my 350 with a new 150 doesn't make sense at the current prices.

Thanks for the help

 

17-18 is good, if not great. You are not going to do much better than that. Which engine?

 

yeah^^^^ and what year? I get 17 with my 01

 

Moved to the 6.4L Powerstroke Diesel forum.

 

What you said for your mpgs is pretty good. Short of tuning and getting rid of the dpf I don't think you will do much better.

You could try to change your gear ratio to effectively raise your gearing but the net gain would not be worth it.

Better off just calling it a day. So why did you get rid of the 5er?
