On the first tank, mixed driving, no towing, I got 16.5 MPG. On a 150 mile trip today mostly hwy driving @ 65 MPH, the result was 18.2. That is about a 40% increase over the 2008.

Running at 65 MPH, the engine was turning just at 1500 rpm. The 2008 turned 2000 rpm at 60MPH. I may be wrong, but I expect as the engine approaches 3000 to 5000 miles, there should be a 2 to 4 MPG increase in the mileage figures. We will see.

With 500 miles on the truck, I am now ready to tow. The tow from here to Colorado will give me wide variations of terrain conditions to discover its towing characteristics and associated mileage.
