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

[Strjock81]

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.

Good looking report, especially considering the GDI engine.

Another high Moly oil doing an amazing job.
15K mile oil change and it’s still looking great !
Even at $12 bucks a quart this is an affordable oil
Thanks OP

Thanks for the feedback. Wish I’d have just left it in for 20k but was starting to get nervous.

Blackstone is guessing on Flashpoint. The 46 ppm of iron must be from the esters and the "scavenger effect." IMHO, you are good for 20k mile OCI's. Successive OCI's should trend better and better.

Unless I’m missing something, iron ppm per mile are better than the average sample for this engine.

326 miles per ppm FE on my engine

291 miles per ppm FE on universal average

As an unrelated side note, I ran one PEA fuel treatment during this OCI and a couple Italian tuneups
