2021 LC200 w/20K ODD Oil Sample Analysis?

[TeCKis300]

BLUF/TLDR - It helps me establish rationale for my continuing on the 10k OCI.

For me, it's to see whether or not the oil I have in it (Amsoil SS) is still protecting my engine after leaving it in there for 10k miles. Having the TBN value lets me know it's still got some left in the tank despite my changing it. I know people consistently poopoo on leaving oil for more than 5k miles, but that is old school thinking IMO given how far we've come compared to the 3-5k OCI's. I also like to see the insoluble levels, etc to see how the filter and engine are fairing given the miles/hrs on the engine and oil/filter combo. As others have experienced, my copper was also high. Lots of reasons given by Blackstone for this value being elevated, but no consensus yet on why it's high on so many late model 200s. Good to have more data so we can figure out what (if anything) needs to be addressed given this elevated value beyond what's considered a normal value (bushings, bearings, etc). Hopefully yet another thing I have spent money on for no other reason than it makes me feel educated on why I do what I do.

Counterpoint. Would have likely spent less and maintained an overall healthier engine by just using normal oils and OEM filters with the factory recommended OCI. Analysis like these are trying to re-engineer best practice via limited data. I say limited because the factory isn't just considering TBNs.

And I run 5W30 from 2500 miles on

Yes, approximately. I did not take a sample at the first change and this sample I did take was days after a 5000 mile road trip with towing. I don’t expect there to be a uniform wear in profile but there should be similarities like a gradual reduction on the wear metals in the analysis. It should be noted I am running 0w30, not sure if that would make a difference or not but it is slightly thicker.

Just curious what value the Blackstone reports are for each of you? Is there anything that you can actually act upon other than sticking with the Toyota recommended service interval? Not trying to be flippant - just not sure what the value is of the data if there is no action coming out of it.

Note: I totally get the value of Blackstone analysis for fleets and HD trucks, marine, and aviation. Just have no clue of the value for one off personal vehicles.

Excellent points/questions. Here's my reasoning...

almost 2 years ago I completely rebuilt my 1fz-fe ('97 LX450): The whole shebang, Pistons, rings, main and rod bearings, and MUCH MUCH more! I loved every part of it, especially tuning the key after all that work and it ran great.

I mentioned doing an oil analysis to a guy I know who runs the service department at a FORD dealership, he said it was a waste of money. I did it anyway and the analysis detected a small amount of coolant in the oil. I won't bore you with the story (I did a write up on the 80 section) but, back and forth I went trying to figure out the issue. I did fix it with and new oil cooler and cover. Luckily, the amount of coolant was small enough to not do any damage, because - I knew it was happening. Subsequent reports are excellent and I'm living happily ever after

So, why did I do a report on my '19 200? No real good reason, really I'm a bit of a data geek. I baby/spoil my vehicles. I routinely get just over 21mpg hwy, so I know it's running fine - I guess I now have a baseline and won't do another analysis for a long, long time. I have a '13 Taco with ~95k miles and I'll do it's first analysis for that pretty soon, as a baseline.

There you have it. I'll shall await behind the MUD woodshed for my obligatory beating

No beating from me… fellow data geek

Throw me a bone here… I’m trying to talk myself down lol

I’m sure it’s break in levels.

For those interested, I received my second report today. I changed oil a little earlier than I had planned because of a massive road trip we have coming up. Copper is half what it was, whew.
