WOW!! 17 MPG.........I got all excited Saturday when after a 120 mile road trip I checked my MPGs and got 14.3 MPG. My truck is an 06 F-250 Reg cab, 2wd, 4:10, and a 6-speed manual. Now the 9 to 10 city MPG I can confirm matches mine.
I can get 17 MPG on my 03 F-450, 6.0 PSD, 4:30, 4WD, crew-cab if I keep it around 55 MPH. So I'm not saying 17 MPG with the V-10 can't be done. I just can't seem to do it.
I must say that I do enjoy pumping unleaded into the V-10 a whole bunch better than diesel into the 6.0.....
As of time of fill ups this morning Unleaded gas: $2.98 Diesel: $3.69 per gallon

radio flyer - 17mpg is great. The norm seems to be 12-14 on the highway. Is that 17mpg imperial gallons? About 14 miles per us gallon is equivalent to 17 miles per imperial gallons

With the truck in my sig, 13.5mpg to 14.5mpg city/hwy mix, to/from work are very consistant numbers, 16mpg hwy is a no brainer.
I do not have 4X4, there are only 2 wheels out back on the one axle, and a stick to stir the gears. I ordered it that way, may be tough to sell down the road, but that isn't happening until there are 300,000 miles on the odometer. At least that's the plan anyway.
Enjoy,

Stick vs automatic mileage....

If you have an identical final drive ratio, a stick will always get better mileage than an auto (even with a lockup torque converter in the latter) because the automatic is always leeching some power to run hydraulic pumps that do things like keep the truck in gear, lock up the converter, etc. Probably not a major diff on a V8 or V10, but this kind of stuff will always hurt a 4 cylinder car bigtime.
Even with the new autos that use solenoids for a lot of control functions, it takes electrical power to keep a solenoid activated, and that uses *some* horsepower thru the alternator....
