It is immaculate! The owner(s) must be prior military. The plant has that look and feel to it. Most impressed!

...and here's the PCMO. https://www.hplubricants.com/wp/wp-content/uploads/2020/06/PC-Engine-Oil-PDS.pdf

I believe that Mg is generally more expensive than Ca in the DD package. I further believe _that_ is the primary reason oils have shifted away from Mg toward Ca over the years (decades?). Even in the '80s, we chose an all-fleet oil with higher Mg levels than the 'typical' oils were using at that time, because we believed it to be a technically superior approach.

It would probably take me a while to track it down, but some time ago I posted a link to a lubrication industry paper that reported that magnesium based detergents had the capability of interfering with the beneficial synergistic effects of ZDDP and MoS2 in motor oil. The fix that was reported for this was the use of a boron based additive, IIRC...the details are fuzzy. Anyway, I took this to be a possible reason for why calcium based detergents were far more prevalent before the LSPI issue raised its ugly head...using magnesium required some extra care in the oil formulation. Just my own thoughts and quite possibly completely wrong and useless...

Free shipping on orders >$100 or $150 would be nice.

I won't rule out I'll buy some 0w-16 for the Camry.

That would be interesting to read. I assume you mean a Mo compound other than the disulfide(?). I don't think a reputable formulator would put MoS2 in an engine oil, would they? In the timeframe I mentioned, Mg deposits were also reported to be ‘softer' than Ca deposits, another factor in the decision to use the fluids we used.

Wrapped up a 15k interval on the oil I got on this trip and had a UOA done. Enjoy!

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.
