Citiboy, you'll be lucky to get 10mpg with 38's. The best I've seen is 12.7 between fill ups. That's doing the math, not trusting the DIC. We have Hummers. Why are we talking about gas mileage anyway? We all know it sucks

I easily got 15 while stock. It's not uncommon.

I call BS---I've got a lead foot and can't claim mileage. But my wife drives like an old lady and has only ever pulled 12 on a tank after multiple tries. I can't see it getting 3mpg better than that "easily".

MAYBE an 08/09 truck, with stock tires, and a very light foot on the pedal.

Stock my 04 was right in the 12.5 or so range, on a mostly highway trip I could get around 14.5 +/- assuming there was no wind.

With 37's and a Hypertech Max Energy I'm at 10.8, that's about 30% highway, 70% city. Without the tuner, and on 37's I was in the high 8.something low 9 range. Although, within the last couple of months I've turned off the DIC all together and just drive the thing, there's no point in obsessing about it.

There was a time, a couple of smart phones ago, that I had a photo of something like 26 mpg (instant) at 75 mph! ... of course that was in about a 30 MPH tail wind and down hill!

I have 106,000 miles on my H2 and haven't reset the mpg lie-o-meter since the day I brought it home new from the dealer. It currently reads 11.0 mpg. I got a 0.2 mpg boost around 50,000 miles switching to Mobil 1 synthetic. I do a lot of highway, towing. winter snow and mudding at construction sites.

I'm getting 10.5 with a 6 inch lift and 37's and am very pleased with that.

I'm gettin' 11.5 with a Cognito UCA leveling kit, 1" rear spacers and 37's; when stock I was at 12.5.
