I have 6500 miles on my 03 and just finished a 2000 mile trip. I did no towing, but here is what I got.<br><br>Stay below 76 MPH and I got 21.8 MPG. Go above 76 MPH and it drops down to 18.1 mpg. None of this was off the computer, all based on gallons pumped.<br><br>So I stayed at 75mph and was a happy camper. ;D ;D<br><br>By the way it is a crew cab, long bed, six speed, 3.73 gear and HO engine.

 

I am on my 3rd tank of fuel. 1st tank was 17.9 city highway, 2nd 18.5 city highway and 3rd tank I was crusing on a slow highway just under 60 and got 27.0 which is good as I can hope for. This is all in the US miles calibration. Double checked the 1st 2 tanks the longhand way and the computer is really close. I do tend to drive conservatively though!

 

Just drove about three hundred miles through the mountains today (Sierra Nevadas) The longest drive Ive taken my truck on Averaged 18.9 speed between 55 &amp; 75 at one point cruisin under 65 I actually had it too over 20

I dont think thats too shabby for a 4X4 with 1700 miles on it
;D

 

Towing at 100km I get 13. Towing at 120km I get 10.5, towing at 130km I get 9. Trailer weighs around 7500lbs.<br>Empty @ 120km I get 14.<br><br>jt

Or if my math is skewed tonight, you're saying towing at 62 mph returns 8 mpg? Seems kind of low to me for a 7500 pound trailer. Now if we correct for the GIQ gallon, it gets a little better, but still seems low.<br><br>How much is dsl fuel in Ontario now? I may be visiting in a month or so pulling the boat.

 

Isnt their gallon bigger than ours also?

 

No more gallon up here but yes it was an Imperial gallon which equalled 4.54 liters US Gallon = 3.78 liters.<br>I do believe he has converted to miles per gallon.<br>Still seems low.
