I think if I was a salesmen I would research the products I would be selling. I wouldn't like it if a customer came in knowing more than me.

Mine gets pretty bad mileage at 180 mph. Maybe I should get a bed cover.

This was taken last week when I filled up. So far I have put this many miles on the truck. Hopefully it stays like this. We will see.

I have been very pleased with my MPG in my Denali 6.2 (4x4 but running in of course 2wd).

 

I currently have 670 miles on it. This screen shot is on winding roads and hilly too. I am very impressed.

 

 

My 400 mile average is 19.2

I'm at 1645 miles with lifetime MPG at 15. I get like 11 city and 19 highway with about 50/50 mixed driving. Not going to lie though, I am optimistic about future mileage because at like 800 miles my lifetime MPG was 12 and it's only getting better despite hills/snow/and winter blend gas. I'm hoping by like 2500 miles to be getting 17 blended MPG (winter blend) and like 18-19 blended MPG (summer blend).

Ok, my second fuel tank is about done...lasted about 3 days. Right now I have a quarter tank of gas left and I have driven 224 miles. This is what I have noticed about my truck.

 

1. The truck definitely FEELS like it has no real power

2. I have to stay in the gas pedal to maintain speed.

3. If I let off of the gas and try to just "coast" my truck instantly starts slowing down as if I were slightly breaking even when im going down hill.

4. To get up to speed on the Highway I really have to get on to the gas and hold it there other wise I will go from 70 to 60 with in 3-5 sec.

 

This is the first actual pick up I have ever owned however, I have owned a Suburban since 2006 (recently traded for a 2010) but they both maintain their speeds a lot better.

 

Not sure what to think...

 

I complete agree with the highway comment. I need to constantly keep my foot on the gas to maintain speed which is annoying as hell on the highway. I don't like cruise control because of all the hills here and it actually makes my mileage worse due to the hills so screw it.

My lifetime average from the Onstar app is 20mpg for 5500 miles. More in town driving here lately and the average is down near 17.5 lately.

I'm back up to 17.3 MPG in the City after dropping to 14.1 during our last storm and me driving her in auto. I'm once again pleased!

For the record I have seen no change in mileage and I have had all the ECM/TCM/BCM updates completed. My gallery has DIC photos of mileage. Right now I'm at 12,500 miles and still consistently getting 20mpg with 34" tires. I usually go about 450-500 miles/tank. My best tanks have been 20-22mpg on highway trips at 75, though I have seen 24mpg at lower speeds (photos in my gallery). Hand calculations are generally within 0.5 mpg of the DIC display. The stock trucks I test drove were showing about 2mpg higher than my truck with oversize tires. And yes, I have a Hypertech so my figures are corrected for the tires.

Daniel,

 

How do you get to that "average/ best" screen in the DIC?

Hello all, I am new here and apologize if this has been covered already. I have done a lot of searching and couldn't find anything on this. I am wondering if anyone here can share what kind of mpg they are getting with the V6 in their new trucks. I am going to be buying a new truck next year and right now I am going to go with the truck that nets me the best mpg so I can ditch the commuter car and use it as my daily driver. I currently own a 2011 silverado with the 5.3 but this v6 has plenty of power and towing capability for what I need. I am also considering the new colorado but I need to check it out in march at the car show before I will know if i like it or not. So anyone who can share what they are getting and in what model truck would be appreciated. Thank you

I have a '14 Sierra Double Cab 4x4 w/ the 4.3L. I only have about 1800 miles on it so far. I get about 17-19 in the city / suburban-rural driving, 21-24 mpg hwy. It seems to be improving a little bit and if I kick it in 4x4 I lose about 2-3 mpg in the city, I've not used the 4x4 on the hwy enough yet to comment on that aspect but I did do a 300 mile round trip and got 22.5 mpg two days after I bought the truck. I do wish I had the $$ for the 5.3 as it only knocks down the city rating 1 mpg in 4x4. However the v6 has the power just have to put the hammer down a little further than I'm used to at times/

It's one of the pages in the info menu. If yours isn't there, try going to settings on the DIC to enable it.

Hmm, I'm getting very similar with the 5.3. I lose a little more when in Auto.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
