Well,

According to the trip computer, and the website Torontogasprices.com, I am getting 20MPG, or 11.7 litres per 100kms. Both are pretty consistant. I do not really beat on my truck though. I drive almost like a farmer. Usually, 100km on the hiway. Went I beat on the truck, I watch my milage go to 14 litres per 100kms.

 

At 110km/hours (do the math, sorry, I' M Canadian) I'm averaging 19 and would hit 21 at 100km/hours.

That is with the 4.7 HO AWD with KO's BFG 265. Better than my 2003 Durango R/T use to be, way better.
