6.2 High Mileage Club

[Bamacommander]

Just curious how many miles you have on your 6.2, and if you’ve had any issues. Anyone with a 5.3 can also chime in.

I put 200,000 on my 2012 5.3L trade it in on my 2019 5.3L 8spd Denali

Had 107,000 on my 2014 6.2 with little issues before I traded it in on a 2019 6.2. Got 32000 on the 2019

But that is an LS based motor, not an LT. The LS engines are a different (arguably better) animal. They routinely go 300-400,000 miles with cheaper easier issues. The LT 6.2 is a hot rod but LT based as it be its not as durable or long lasting as an LS. There are high mileage ones but they have not faired as well as the LS. Just has more going on and more issues long term .
