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?

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.
