What are you guys getting as far as gas mileage goes in the L86 6.2Ls? I'm pleasantly surprised with what I have been getting.

These GM SUVs get fantastic mileage....especially considering how comfortable they are and how well they perform. I think GM knocked it out of the park with the Direct Injection technology !!
On a recent 400 miles road-trip, had no problem getting 24mpg at 65mph and that was with going up north and encountering tons of elevation changes. I did not use any hypermiling technique, just set the cruise and forgot about it until the end of the weekend.
I am also quite impressed, oh and that's withe the stock front deflector removed and the shorter police deflector in place.

Best I've gotten on the highway is 23.5, but consistently 20 on the highway. City is much less depending on a lot of factors, but consistently much much better than my '09.
I calculate miles driven by gallons at fill up. I typically see less than a 1mpg delta between the trip computer and real math (trip computer always on the optimistic side). I do top off every time I fill up so that could be a contributing factor??

I have been getting 12.6 mpg since I lifted it and installed 35 in tires... Before that I averaged 18 to 19 mpg 90/10 highway/city... I will be installing new gear sets next week going from 3.43 to 4.88 I hope to se some of my mileage come back.
