Re: what are you guys getting for mpg?
My DD is an '07 suburban 2500 6.0l 4x4 and 3.73's (I think) and I get around 12 city and 16 hwy (avg speed of 80).
After reading this thread I am not quite as disappointed in the mileage it gets but would like it to be better...
Any suggestions that have netted you actual performance and economy results?
