2024 Sierra Denali Oil Change. I got 4 with the 2018 lml and 2 with the 2022 3.6 acadia. We get a free gmc oil change but we will probably not turn 4k a year on this vehicle so looks like next oil and filter will be on gmc at around 3k.
Someone mentioned something about build up soot and the fix was to install an s&b spacer. It’s time for the first oil change on the 2024 denali ultimate 3500 hd.
