I've been able to get just over 20mpg highway in a 2005 Chevy Avalanche Z71. I'm looking to possibly purchase a 2500HD My question goes out to the Chevy/GMC 2500 HD 6.0 owners. (The smaller engine).
What do you get city?
What do you get highway? and what do you get mixed? What is the highest MPG you could get? Your advise is greatly appreciated!
