Re: Fuel efficiency...what MPG do you get?

I borrowed my dad's 2014 C10 (do they still call them c10's?) 2wd, small v8, for a highway trip and got 17 mpg @70 mph with cruise on and tach about 1600 rpm's. Any square getting close to that is getting phenomenal mileage imo. My 76 GMC K15 with 350/th350 308's can knock down 11 mpg all day long. 65 mph is around 2500 rpm's on the K15.
