My 2015 Yukon Denali has over 400,000 miles. It's 10 years old today!

Hi guys: Well I didn't really think I would keep it this long, But here we are. Now I gotta keep it. I guess there's hope for all of us.

Have you overhauled/replaced the engine or the transmission throughout its run?

@tuffguy23
Out of curiosity were you using 87 octane fuel? I read awhile back that is what you were using at that time.

Also how often did you change the oil and was your AFM still enabled?

Just wondering. I have 180K miles so this gives me hope.

very nice. I’m guessing full synthetic every 5k miles.

Thanks Guys: Yes 0W-20 and filter every 5k miles. I've only ever used regular gas. 8L90 trans had a torque converter replaced about 8 years ago. I do fluid and filter on it every year. I replaced cam and lifters 5 years ago. Still running stock AFM. I do try to stay on top of all the maintenance items. So far, i don't really think I can complain.

Amazing. So that means you'd do it again?

That's awesome
My 2016 is still in diapers comparatively
It has 94,000 miles on it.
Lifters and cam replaced 18,000 miles ago.
Transmission temperature sensor harness and all fluid changes, kept up on otherwise. There is hope !!!
