6.0 powerstroke mpg
 

guys i not a ford guy so i need some help, got a buddy that has an 05 and gets 12mpg unloaded bein easy on it,he want to do better but he wants to keep his factory muffler what can u do to one of these to get better mpg on a budget:humm:

78 people have looked at this tread and no ideas what a bunch of bs,there sure is a bunch of unsociable pricks on here :moon::moon:

sad you feel that way... put an edge juice with att. run on stage 3 or 4 and go EASY on it, been said you can get up to 25 mpg but will lift head bolt in the future.

What's the budget? Is the truck stock? Is he willing to run a tuner? Can he do the work himself? Does he tow regularly? :moon::moon::moon::moon::moon::moon:

The Motorcraft Cetane Booster added about 2mpg for me and it's CHEAP. About $8 treats 100 gallons. Why does he want the stock muffler? If he's worried about noise tell him to get on youtube. You can hear damn near any exhaust on a 6.0. This way he can find one thats not too loud. As for me its 5" straight piped (loud and proud).

he want to keep the stock muffler cause he doesnt know any better and he is going to do a programmer i was more less wondering what the best way as in brand and he does tow 10,000 every once in awhile,budget 500-800

Get a custom tuned SCT, modify the EGR up-pipe, swap the rear diff cover to the '08 style, get a friend that drives a PSD.

i got plenty of so called friends with psd,they dont like me much cause there power junk ford wont hang with the d-max

our 05 6.0 gets around 12 unless it is 100% highway then it gets around 18. Has a edge juice. 50,000 miles next to no towing and never raced it is starting to puke coolent. Best advise I have is keep it stock or go all out starting with head studs.
