No, I'm getting 17.5 if I keep it under 65. No idea what I'd get at 55 - 60. That's with a custom tuned PCM (powertrain control module) that I had burned for $160. Prior to the tune, it would average 16 mpg.

And that's driving over a mountain range from sea level to 3500' and back down to see level again.

Considering it comes from the factory with 345 hp (380 with the custom tune), all wheel drive and a 4.10 gear ratio, 17.5 is amazing gas mileage for a 5500# crew cab pick up.

Around town / city driving is a different story......it sucks.....more like 11 mpg. It might get better, but I'm not known for driving very mellow. I drive and ride everything like I stole it!
