Motor Trend is reporting 23.2/31.4/26.3 (mpg city/highway/combined) when they tested the Colorado Diesel.

I'm curious what everyone else is getting.

Post your numbers in here!
I have the Z71 4x4 short bed diesel since mid January. I just returned from a near 1800 mile road trip towing a 2 ton travel trailer... averaged 16.0 mpg. Running around town 25.5 mpg. Don't really use it unloaded on the freeway, so not sure on Highway miles... love this truck, though.

While driving 25-50 MPH I am seeing city at 30-45.
On the Highway 35MPG on level ground, but my average is pretty low due to a lot of traffic driving.
I live in Los Angeles.
Even still it is at 23 I have over 9000 miles. I did a 2200 mile cross country trip north on the I5 LA to a little past Portland.


Though, when I hit the 800 mile range I had a whole day where the MPG's went down 20 MPG's.
I have had this happen to me 2 or 3 times.

Is this a side effect of DEF and regening?

All of my mileage is based on miles and the gas pump, not the vehicle computer...

1827 miles at last fillup and I'm averaging 23 Mpg per tank. Highest is 24.2, lowest is 21.7. All with ULSD... Front air dam removed, Thule XPorter racks flying in the wind as well. Lots of city driving, I'm not "gentle" on the throttle and it's been near 100 degrees regularly here.

It's running about what I'm expecting, will continue to post as it changes.

I just picked up my ccsb with the all terrain package on 8/6/16. It now has around 700 miles on it and for my first tank I averaged 22.4 which I expected since it was about 95% city driving and idling showing it off and etc. This morning though I drive about 20 miles of highway one way for my commute and my instant was reading only 17-19 with cruise set at 75, rpms right under 2k and no grade. This was for the first about 18 miles, and for the final 2 miles it went up to 30+ and it did the same on my way home, crappy milage at first then improved. I really hope my milage improves or the instant is reading way under.

My truck has about 1800 miles on it and the lifetime mileage shows 25. But I've towed my 23' center console a couple of times and a few other trailers.

According to the DIC, I get 30-32 mpg on the interstate at 72-74 mph. I live in mostly flat terrain.

On a tank of mixed city and some highway driving I'm getting mid to high 20s.
