#228 of 237 Recent Trip Milage by firecapn Jun 18, 2008 (4:53 pm)
Recently got back from a trip up to Indiana Dunes. Spent the weekend and return on Sunday. Have a F-350, crew cab, 2WD with 6.4 Powerstroke. Got about 11.4 mpg going up and 11.9 mpg. Truck ran like a dream pulling my fifth wheel travel trailer ( approx 13500#s ). While enroute had a exhaust cleaning occur with no loss of power or noticable mpg loss and no smoking. With 6500 miles on the odometer all is great.

Replying to: firecapn (Jun 18, 2008 4:48 pm) I have the same engine as you. The 6.4 power stroke diesel, with an automatic tranny. It gets fair fuel mileage. Been to the dealer 2 times, is at the shop now. The computer says it is overtermp. exhaust temp. module. was changed then got 35 miles down the road and it quit. The days of the mechanic is long gone all they have now is parts changers. Whatever the computer says is the problem!!!!!!!!BS to that.

Can any one give a suggestion on which air intake they like for the 08 supers. I hate my new 250 and am desperately trying to do something to improve towing and maybe mpg when empty. I only get about 11 around town. I did the worst thing when I traded my 02 350 with the 7.3 in for this hunk of crap.

Some of you, who are getting upwards of 10 MPG -------- consider yourselves LUCKY! I'm currently RV'g throughout Washington, Idaho, British Columbia. While our Lariat is a great truck in most respects, it's a PIG when it comes to economy ---------- averaging less than 8MPG with a 10,000lb 5th, while trying to do everything to "go easy" on fuel economy. 80PSI in tires, easy starts, 55MPH, TowHaul on where needed, etc. My brother (after 9 new F350 Diesels in the past 10 years) is trying Dodge's "equivalent" with the 6.7 Cummins. He consistently gets 40>50% better economy on the same trip. BUMMER! RUDY
#234 of 237 08 F-250 by fordfan08 Jul 17, 2008 (12:46 pm)
I'm looking into getting an 08 F-250, but I'm not sure what Engine-Transmission-Rear Axle Ratio to get: 5.4L V-8 Gas-5 speed Auto Transmission-3.73/4.10, 6.8L V-10 Gas-5 speed Auto Transmission-4.10/4.30, 6.4L V-8 Diesel-5 speed Auto Transmission-3.55/3.73. What will give me better MPGs?
#235 of 237 transmission? by contractnow Jul 17, 2008 (2:37 pm)
You need to decided what your hauling then decide on trans. my '08 250 gets 15-16 mpg it's a 373 rear. and I haul nothing. If your huling heavy stuff you need the appropriate rear. Diesel will give you the best mpg but reg. gas is cheaper. So you'll have to do the math and decide, Sorry, but good luck! I love my truck other than the diesel price.
