Oil for 2015 Yukon XL Denali 6.2

[Strjock81]

I ended up picking up a case of quarts of High Performance Lubricants 5W-30 HD at David's suggestion for summertime towing and such. I sent off a VOA and plan on doing UOA when the OLM gets low, will extract it with my oil extractor pump so I can see how long I can run this fill.

Ended up going with HPL 5w-30 and ran it for 15k. Here are the results.

Yukon Denali 6.2L, HPL HP 5w-30, 15,000 mi OCI

Mixed driving, some towing, mostly long highway trips and errands. Was warm for most of this OCI but 2 months of cool-cold weather. As expected no big deal for HPL but happy to see the engine is wearing nicely as this is the first UOA I’ve done on it.
