What's the highest mileage AFM motor you've seen or own?

[tuffguy23]

Wondering how far a AFM motor can go, I'm about to turn 100k on my 2017 5.3 6L80 with disabled AFM since around 50k miles.

Anyone own or hear of really high miles on an AFM motor?

Anyone hitting 200k, 300k, etc with AFM disabled?

OK guys. I just hit 400K in my AFM motor. 2015 Denali. I'm hav'in a good time with it.

Wow! That's some use! I thought I (we) put on the miles, but you put me to shame. LOL

The proof is in the pudding......lots of miles and long stretches of running tearing up the road is what a vehicle likes.

6.2L I assume? What have you done as far as maintenance? Any issues with carbon buildup on the valves?

I am at 360K and the motor is getting replaced next week. I am not waiting any longer for the inevitable to happen.

173k on 2016 5.3 stock tune and 10k oil change intervals with Mobil Delvac 1 ESP 0w40. I realize this is a pretty unconventional choice and I run it for a lot of miles but I will put cam and non dod lifters in at first signs of a problem. We have a very mixed fleet and this oil is in almost everything from large diesels to small air cooled engines for the past 7 years and no oil related failures to date. Roast away!!!
