Thank you for all the kind comments everyone!
I just got home from Florida (yep bought it in Fl and drove it home, everything similar here is 5 to 10k plus more)
I topped off the tank about two or three exits above the Florida Turnpike on I75 North. I have just unloaded the truck from our luggage and stuff. I made it home without filling up again after filling up north of the turnpike. I’m going to hand calculate it when I fill it up tonight but here is what I have on the “lie-o-meter.” I have about 1/8th of a tank left and the gas light has not came on yet. I have to confirm it but I think this truck has a 26 gallon tank too.
25.4 MPG. And 505.9 miles traveled on this tank so far. This truck has 3.42 rear axle ratio.
I never got 500 miles on a tank with my Tahoe (5.3l, 26 gallon tank, 3.08 rear axle)
So far, I’m impressed. I know I’ll be in the turbo more towing so we will see how that goes. I expect 7.5-9.5 mpg like every other gasser I have had.
Thanks!
