Man I would love to get the fuel millage some of you guys are getting. All my driving is in town with my 05 cc 4x4 on 35s and a very heavy foot and I normally get 9.5 10.5. It never really bothered me because thats what I averaged in my lightning I had and diesel is so much cheaper than premium.

I am new to the site and have an 06 250 4x4 3.73 and 20" rims with 18k miles -all stock- getting 11.8 to 12.4 empty in town/ 10.4 pulling 29ft 5th wheel. Any suggestions on increasing mpg's? Thanks

I have a '03 6.0 with 126,000 miles on the odo and climbing daily. My average mileage is a combined 16-20 "city" and 22-24 empty on highway. I drop down to around 9 under load with a 25' V nosed enclosed trailer towing around 10,000 - 12,000 pounds.

Highway speeds I usually am around 70.

Mileage seems pretty good on a stock 6.0 weighing in at 8K pounds.

Do you use vegi oil right out of the bottle or is it recycled?

I have a 2000 250 w/ 7.3 My mileage is about 14-15 average (mix of highway and city). I haven't had much luck with raising it. I've raised tire pressure and added a air cleaner, windows closed, no heat or AC, ect... I'm very light on gas pedal. Maybe it's the colder weather. I'm thinking of getting a tuner from Jody 80 econ. Has anyone done this and actually got better mileage? ($3.5 gallon in Maryland) Thanks

well in the winter they switch to a different type of diesel which normally gets you worse milage.... don't know when they switch but i think it's once it gets below freezing.. it doesn't gel up as easy
