I know guys like to see numbers so here are a few from a recent trip. I was unloaded and had one passenger.

Fuel: 91 octane non ethanol on trip up. 10% on way back home.
Miles: 373 miles one way
Weather: 50 deg rain and fog

I ran 80-85 on the way up and got 16.0. On the way back I ran 75 and fought a head wind. I got 15.5. I wish the numbers were closer to 20 but such is life.

 

GeArs, 4x4? Long box? These can swing mpg by a couple...

But at 80-85 what do you expect?

 

Tell us more. Truck, engine, gears.....

85 is ptetty fast!
