Just crossed 4000 miles with a 19.2mpg average.

Nice! I just hit 7000 miles and have a "lifetime" average of 17.7. Reasonable considering I have spent a fair amount of time idling with a toddler napping in the back in between drs. and therapy appointments. Glad to hear your truck is living up to your expectations. Aside from the thin paint I love my '14 sierra.

19.2 is very good. That's a full mpg higher than my Ecoboost, its average is 18.3. It's a Super Crew FX4 with 3.73 gears.

Have you hand calculated a few tanks to verify the dash? My ford is never off more than .2 mpg, so it's very accurate.

Chris

I hand calculated for the first 3-4 tanks to get an idea, and it's very close to the dash computer -- usually within 0.1 or 0.2 mpg. Thing is, there is some error in refueling since we can't get the tank to the same perfect "full" every time, and being off 0.1 or 0.2 gallons on a 26 gallon tank will introduce plus/minus 0.1-0.2 mpg error. I'd almost trust the dash computer more than hand calculations, as it's using realtime mpg = mph/gph data.

During weeks when I only commute highway with the truck, it usually ends up at 20-21 mpg at the end of a tank. Tanks with mixed driving, work, or towing tend to average 17-20mpg by the end. The current tank sat at 13.2 mpg after a weekend of firewood hauling on my property, then crept up to 19.4 mpg by this morning's commute. Highway miles really impact the average.

Thats great millage. The 3.42 gears really help in your situation. I couldn't live with a gear like that but that's why they make about a million combinations when it comes to trucks.

I just bought a Silverado 4X4 crew cab in white diamond. They threw in LineX spay on bed liner. I'm loving it.

Thought I'd bump my thread for a 1 year update. Truck is doing great, and gets used heavily for projects hauling lumber and building materials, and towing my 7x16 trailer (tow about 1-2 times a month). No problems to report. Truck was in once for a recall (computer programming) where I had them check and adjust the alignment, then again for my annual state inspection, then once more for the free 7500 mile service (oil change, tire rotation, etc -- those are free for the first 2 years).

Gas mileage continues to be great, though I noticed a slight dip during winter months. At just over 8600 miles, the average is 19 mpg, which is excellent considering all the hauling and towing the truck does. During weeks when I just use the truck for commuting, it's typical to get 20-21mpg per tank, and on a long trip I will see 22-23mpg. I consider that excellent for a V8 crew cab 4x4.

If I had to buy a truck again right now, it would be a wash between the GMC and a new F-150. They are so close, any little factor could sway me in one direction or the other. Steering and handling continues to be a strong point for the GM trucks, and is unmatched in the class. Ford did not improve the steering or handling with the new F-150 that I can tell -- it continues to have typical numb/disconnected steering feel. That is disappointing, considering they use electric power steering, which makes it trivial to impart some sort of handling feel/feedback even if it's artificial. So that would be one factor that would keep me interested in the GMC.

That's great gas mileage. It's up there with my wife's new MKS Eco boost, which I'm not to happy about.....

That's excellent mileage. The 3.42 gears helps a bunch. My Ecoboost with 3.73 gears has averaged 18.3 mpg since new, 57,500 miles to date. It gets about 21 mpg on road trips and about 13.5 mpg pulling 6,000# and 9 mpg pulling 10,000#.

My father and uncle have the same trucks but 3.55 gears and get about 1 mpg better across the board but neither tow much more than 5,000#

We are all using 87 octane E10 fuel. Sure wish we could get real gas here.

I get 13.7 mpg in a 2013 F150 V8, 3:55, 4wd, orig tires (an open hiway tread).

It has 8,000 miles now. The dash claims 14.7 which is sorta close to hand calcs. I drive like a grandpa, accelerate slow, brake gently. On the Fwy I set cruise at 74 though. I must calculate mileage like a grandpa too.

I didnt buy the ecoboost because of a bunch of folks claiming they got 20mpg with their V8s. I think this is a YMMV situation but I would like to get better mileage.

I sure like this truck!! Would like to spend less on gas.

I had a guy around recently that just purchased a new V6 2015 Colorado,4wd,crew cab.Nice truck and he is real happy with it.He claims his best mileage(trip computer) was 23.1 mpg,I didn't tell him my full size extended cab 4wd.was 22.9mpg.(5.3 v8).
