Used Yukon XL Denali advice?

JKeller · Nov 5, 2024

I've got 85,000 miles on my 2021 6.2 and about 15,000 of those miles have been towing. I run 30w Amsoil oil and at least 91 octane. Zero issues. I think it's a great engine.

We bought used 2021 little over a year ago with 49K (a Hertz rig) and 6.2L. Have towed 7K miles so far and all working smoothly. Added a curt brake controller and auto-stop. And... it still has that 'used car dealership smell'

(strong air-freshener spray they used at the dealership)
