I get crappy mileage. I have tried doing everything suggested and I get 10-13 mpg. I can tow my enclosed trailer or just drive and it does not seem to matter. I can drive at 60 mph to 75mph and I get 10-13 mph. I can drive in town and get 10-13 mph. Granted I have a 6 inch lift and run 35 mud terrains so that has a lot to do with it. I get 15 -20 mpg in my 3/4Ton with a 6.0 so I don't get it. What I do know is I love my Avalanche and I get compliments on it every time I drive it. For a 20 year old rig she looks good and runs great. I don't see parting with her for quite some time. I will say when the motor does tire out I will replace it with a 6.0 or build a stroker motor for it. It might as well have the power if it is going to have bad gas mileage.
