Overall fuel economy towing with a F250/350 6.2L Gas

For those who might be interested in the real world fuel economy of the F250/350 6.2L gas engine while towing.... I recently completed the first road / hunting trip with my 2011 F250 and I was pleased with the performance of the truck. I put on about 1200kms of the most demanding miles and the overall fuel economy for the trip was at 32LPH (7.5-8mpg)with the truck and trailer fully loaded. This would not be a good overall average in most cases but I intentionally put the truck through it's paces to see what the worst case scenario would be. The truck had no issues maintaining 110kmph at about 4500rpm on the Coquihalla hwy which really tanked my overall LPH, but it towed like a dream on the long hills. It certainly can't be compared to a new Diesel, but overall a very capable TV.

As a direct comparison my buddies 2017 F350 with the 6.2 pulling very close to the same weight (with the only difference being 3:73 gearing) made the same average fuel economy.. At the pumps we pretty much used the same amount of fuel..

The only difference between the two trucks while towing was a little less gear hunting on the hills with the 4:30's.

So far my unloaded instant average at 110 kmph is about 18-19 LPH (12.5-13mg)and bounces between 16-18 (13-14mpg)at 80 kmph. Overall mixed driving (empty) has bounced between 21-23 LPH (10-11.5mpg)depending on the amount of in town driving I do.

My buddies 2017 with the 3:73's definitely does better when running empty. He is averaging 16 lph+- (14.5+-mpg) at 110 and 14 lph+- (16+-mpg)at 80 KMPH.



Hope this helps someone...
