I have a new 2019 Silverado with the 10 speed 6.2L. I have about 1300 miles on it. The average mpg that I have been able to get is 16 mpg. I feel like this is low. Not to mention I have been babying it. FYI, I did put some bigger tires ( 275/65/20 which is a 34 inch) and a level on it but I wouldn’t think it would make that big of a difference. I had the same setup on my 2017 6.2L and I feel like I got better MPG.

 

Can others tell tell me what they are getting in their 6.2L?

Do you use premium? 

 

Give it some time and i wouldn't worry about it until you get closer to 10k miles.

Yeah I use premium. 

 

Even on the highway, it’s hard to get better than 17 MPG AVG. 

 

Hopefully it’ll get better over time like you said.

Hopefully so.  Just will have to wait and see.  Plus it is winter time but then you live in the south so that shouldn't matter.  I know they change the fuel up north and it effects the MPG.

That’s good! How many miles does your truck have on it?

I think the level and bigger tires hurt a little bit. But around 18-20 I would think is the average. Give it take

I would like to put the same tire size on my truck do you have any pictures? What brand tire did you go with and is your truck a trail boss or AT4?

It looks great was there any rubbing or anything like that? That is the tire I'm looking at as well. I'm putting it on a at4.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
