I sold my 2015 Serra 1500. I'm trying to decide between a 2021 silverado RST z71 with a 5.3 18,000 miles. Other truck is a 2024 silverado LT with a 2.7 turbo. With 11,000 miles. Both trucks about same price. Just really nervous to go with the 2.7. But I way like the 2024 better. It still has over 2 years factory warranty left. No warranty on 21. Any advice would help. Just don't know what to go with.  Thanks!

2.7 Turbomax is a fantastic little engine.  I have one (2022.5) and I love it.  And that's coming from a couple 6.0 HDs, two 5.3 1500s and a 2.8 Duramax.  Easily my top engine of them that I've had, with the 2.8 Duramax right behind it (as slow as it was lol) and then the V8s.  If I had a do-over right now on a new 2024, I would pick the Turbomax again, or the 3.0 Duramax if funds were non issue.  

 

2024 Turbomax gets the 5yr/100k mi powertrain warranty as well, the only gas engine in the 1500s that does and only one of two engines that does in the 1500s, the other being the 3.0 Duramax.  5.3 and 6.2 are 5yr/60k mi.

 

Oh and the current LT dash is much better than the older dash.  

 

2021 is a problem year for DFM lifter failure and them eating camshafts when they fail, unless you can find one with the YK9 RPO code which is DFM disabled due to chip shortage.  

 

Have you driven both back to back to see how they drive to you?  

 

At the end of the day, its how YOU feel about it.  You can read for hours on Facebook groups "eww a 4 cylinder?!?" "sounds like a Honda!".  How do YOU feel about both options. 

 

To me?  How the engine sounds is a wash compared to how it drives, tows, etc.  The Turbomax tows 9000-9500lbs (depending on configuration), 310hp and 430 ft.lbs torque, and can (IMO) do everything the 5.3 can but better.  Even MPG has been better for me, currently my lifetime MPG in 24,000mi is 19.2mpg where in my 2012 5.3 it was 15.9mpg, and my 2019 old body 16.5mpg.  I can get about 20-22mpg per tank in spring/summer/fall, about 17-19mpg per tank winter vs. 13-15mpg winter with the 5.3s and 16-18mpg spring/summer/fall. 

 

Do I love V8 sound?  You bet.  Do I miss them when looking at the whole package so far?  Nope.  I can always buy something down the line with a V8 if I need that emotional sound connection again.

I'm completely ok with a 4 cylinder.  I'm more worried about how it will hold up over 8 or 9 years. I literally did nothing to my 15 5.3 but change oil. It had 129,000 and still ran great. Can't really find anything on people who have high mileage ones.

I am a V8 guy. Always have been. Search the various topics on here about the 2.7 litre using oil. That said, a V8 can also burn oil. As newdude said its really up to you to choose. I really like the big screen in the newer trucks but I will purchase and drive V8s until they quit building them.

Just my opinion.

Unless you just have to get one for immediate transportation, you could always just keep looking.

This does not stop lifter failure... The only thing not there is the Chipset. ALL of the mechanical parts are still there and still prone to the same failures.

I've yet to see a YK9 truck have a failure.  Its not a 100% guarantee of no failure, but it being off is a significant reduction in failure rate.

I`m a v8 guy. But, if you can get by the sound of the 2.7 and don`t pull heavy stuff, I might go `24 with the 2.7. 6 yrs of age with the basic same price.

I like the V-8 sound almost as much as the sensation of speed. When Ford first came out with the turbo V-6 I saw on one of the motor trend tv shows. A simple hand held tuner add 100 hp for just a few hundred dollars. Now that’s impressive. Of course people will say you’ll sap the life out of them doing that. As a lifelong modifier I find that’s not the case. You’re not always testing the limits of your vehicle. I have four vehicles in my yard currently. The V-8 powered is the slowest. My mini van is among the quickest. It’s amazing what technology has produced with engines in the last decade.

No one knows right now, these engines are still too new to discuss the longevity of them with any kind of accuracy. They do seem to be performing well so far, i mean it is not like the 5.3 is a nock your socks of motor, kind of long in the tooth today imo, same for the 6.2, they have not been updated much in over 10 years now.

Bought a 2024 crew cab 4x4 2.7. Love the truck but no original window sticker.  How can I find out exactly what trim it is?

Inside the drivers door is a sticker with a QR code. Scan it with your phone and it will decode the RPO numbers. RPO codes are the trucks DNA. They will tell you what it was built with.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
