DId i already reply to this thread?
Cruising on the highway (read: FLAT) i get pretty good mileage.
91 2500 Burb, 350, 4l80e, 4.10's, stock tire size (31.5's?)
15+ 1/2 way loaded. Driving 70-75mph.
I had a long trip with just myself, cruise control set in the 80-95 range (stupid, i know, lets not go there) for about 300 miles, then 70-75 for the next 300, got 17.5.
Was blown away by that.
Truck as 210k on it, but motor/trans is pretty fresh. Rebuilt/crate at some point recent, runs like a new truck.
Oh, and i run about 2050rpm at 70mph.
