My truck around town gets 14.2 and and much higher on the interstate. I really can't vouch for those numbers since I'm only on my second tank of fuel. My truck is deleted and modified as well pulling 540 rear wheel HP and well over 1200ft/lb of torque depending on which tune I use.

Towing a 5+ ton boat not including trailer weight basic ccsb 15' powerstroke was 6mpg. Smog stuff kills it.


Sent from somewhere with confusion.

With 53k on the odometer I was getting 10-12mpg pulling a dump trailer at 10-12k lbs. Filled it again today after driving about 250mi empty and hand calculated 24mpg. Mostly back road driving at 55-65mph.
