Engines - How many have the Duramax?

[SmittysAT4]

Thrust bearing is failing on the LZ0. Happens mostly before 15k miles.

Okay....... I have been hearing about this... Fingers crossed, I am at 7K and looking for 15K plus...........................

Very happy with the 3.0 in my 2025. 19k miles no troubles.

‘26 AT4 XL with the babymax. Just ticked over 1,200 miles and am preparing for this. I plan on changing oil every 3k-4k miles and will send out samples to Blackstone Labs on every change. 7k mile oil changes is crazy to me.
