2022 ZR2 - Update -54k miles

Looks brand new. If you trade it in, the next owner will win the used car lottery.

Which ATF did you use? Mobil 1?

A private sale for sure. A dealer sell a carfax will never reflect all that extra care/maintenance unless a reporting shop performed it.

I think so as well. LGZ/LGX are solid. The gen prior was not and had some timing chain issues. They stopped making the LGZ (truck variant in the Colorado) so it will be a very short-lived engine (2017-2022).

I missed one thing: transfer case fluid changed at 52k.

Maybe this is somewhat ignorant... but I think timing chain issues in the previous generation V6 are largely due to people trusting the oil-life monitor a bit too much and using non BITOG-approved oil. I have a Traverse with the LFX-based LLT with nearly 150k... love the power and driving experience, but I don't dare extend intervals based on what I've heard. I've only had it for roughly a third of those miles though. My biggest complaint is the efficiency (or lack of efficiency). Maybe the intake valves need to be cleaned though....

I think you're right. It had a lot to do with that.

I think at that point the OLM was going 10k plus on OCIs. I know my trailblazer would easily go 14k before the light came on... but like even vanilla mobil 1 would go that long in a port injected I6. I run the OLM on my LGZ which at most is 8k. I dare not push it any longer. Oil analysis confirms that's a safe interval.

I believe that GM changed the OLM default to 7500 miles and/or one year some time ago…it seems to be that on the 2013 Malibu and the 2014 CTS Sport Wagon I had but they may have gotten changed/updated at a dealership service interval between manufacture and now...
