Three weeks ago I had to go to edmonton on business and I was blown away by the mileage. I filled up in edmonton and drove 4.5 hours home and the gauge still showed 5/8 of a tank. It was six days of in town driving before I had to fill it. Its a big tank but still its reasonable!
I havent done the calculations but this thing is not bad at all on fuel.
We will see what a 6.0 does to it ! lol
I suspect this is the best a small block Suburban will do, might help with the comparison or just confuse things.

I would think the lower rear end gears were swapped out for taller gears. A SBC V8 with 3.08 rear gears gets about 20 MPG. Also, my old 89 454 Suburban got about 10-12 MPG; doing 70 AND pulling a 5000 lb car/trailer combo!
