Hi Anthar! Even the Government doesn't supply an estimate for the 8.1l engine trim which is somewhat scary. The 5.3L 1500 gets 12/15 so I guess you can work off of that. Chevy doesn't even list mileage ratings for that engine. Suffice to say it's no good. Hopefully fuel economy isn't a factor in your purchase. Good luck!
