On a carefully ran short trip I got over 29 average.

That's not how averages work. Your best was 29.2, your average can't also be 29.2. You average is far lower, and your worst must be quite low to get an average of 20.

I have averaged 23 to 25 in my hemi v8 and guys on this forum are doing better than that even with the 5.3. So that screenshot there is very unimpressive. Not saying you can't do far better with the turbo than you can in a v8, but that screenshot you posted is not showing you what you think it is, that's all we're saying. In fact its showing you that you got pretty miserable mileage all things considered.

Ok I’m not going to explain math to you. The average and best were many miles apart. My average dropped during 50+ miles of aggressive driving. I said that already. At one point prior to the pic I was averaging 29.2.

It must suck to have a 4cyl be just as quick as your Hemi and with better mileage

Yeah and I was born yesterday. You said at the top of your post "I'm averaging 29.2" and then posted a pic showing "best = 29.2" the exact same number down to the decimal point. Hmmmm. Yeah it's me that doesn't understand math. Rather than admit you made a mistake you're going to just double down on being a child; carry on.

Although i havent driven the 2.7 it is interesting to me , my question is if I ordered a ‘21 WT with the 2.7 would i get the “improved” engine or get the original 2.7 ? I was wanting to get a 4x4 and level with biggest tires i could get under it . Is there anyone with this combo and still getting decent MPG ?

I waiting on the slow truck from Santa Rosa, NM at the trail head.....about to pick up my 2022 LTD Custom Trail Boss L3B and will let you know. It was built in Fort Wayne on 10/16/21.

Liking this engine more and more. Some people have doubts because the belief is the 4 cyl is overstressed when compared to the V8....all I can say is that it gains speed seemingly effortlessly, merging on the highway today I just nudged the throttle, picked out my spot, and slid into traffic, glanced down at the speedo and the needle was just past 80mph. Smooth, quiet, and not revving like crazy, I've owned 8 four cyl vehicles over the years, this 2.7 is in a league of it's own.

Will GM ever pair the 2.7 with the 10 speed? Is there any benefit to that? Need to test drive a 2.7 next time come trade-in.

customboss · December 2, 2021

Love this 2.7 thing at 246 miles. Installed poor man’s bedliner today.

customboss · December 2, 2021

Not sure why one needs the 10 speed, so far 8 speed flawless. Early days maybe but the Dexos HP most likely will solve most issues.

I'd love to hear more towing reports. Do any of you guys tow 7000+ pound RV's long distance on a regular basis?

I towed this about 100 miles. It was around 7000 pounds with trailer and machine. Did OK but wouldn't do it everyday. So the 2.7 gets excellent gas mileage and can tow a good size load when necessary. The truck works perfect for me!

What kind of MPG are you getting with that set up ?

In 309 miles (which includes where the salesman had it idle about 2 hours before we picked it up) I filled it up w/ 16.1 gallons a few days ago. Thats 19.2 MPG average.

I am seeing DIC averages on different legs from 21-25 mpg ranges. I do some trick wear in techniques to optimize ring seal and once we get 500 miles on it will change out the OEM oil and oil filter to emphasize some of that change.

This is operated at 7000-9000' msl Colorado Mountains and I am running 85 octane regular fuels. I will be using CENEX gasolines almost exclusively. That first tank mentioned above at 19.2 mpg with a lot of idle was Conoco 85 octane. The torque and power is smooth and amazing really. Quiet which I really appreciate.

Winds here are brutal. A good testing place.

Because the 10 does everything the 8 does , but slightly better. This is no knock on the 8 .

I can’t find anything wrong with my 8 speed. Does quite well. I can’t hear or feel any knocks.
I'm very happy with my 2020 Silverado 1500 2.7 with the 8 speed.
Going on 2 years with it now.

I also think the 10 spd would be an improvement. It shifts great when you drive it like you stole it but I want it to shift more smoothly at a normal pace.

The fluid change TSB helped but wife's Tahoe is still much smoother in all manner of driving.

Otherwise good truck and the turbo engine has been stone axe reliable going on 3 years now.
