Every North American Lexus service center should hire a Japanese man as the director, general manager, or whatever. There's way too many mistakes going on and no real Japanese Lexus employee would tolerate it.
Food for thought, All new engines contain assembly lube along with oil. The first 1000 to 5000 mile are break in period ring to cylinder seating, bearing seating, etc... This is why the assembly lube. Also why you should change oil in first 1000 mile and then again at 5000 or 6 months. Most cars require no special break in instructions. Boat motor however are a pain in the ***. This is example for Yamaha outboard First hour: Run the engine at varying speeds, but keep it below 2,000 RPMs Second hour: Increase the speed to under 3,000 RPMs, but avoid full throttle Hours 2–10: Run the boat at three-quarters throttle or less, but occasionally increase to full throttle for brief periods. After 10 hours: Run the boat at normal operational speed After 20 hours: Bring the boat in for a service.
After the 3rd oil change you should end up with normal numbers till something goes wrong. Seeing as it is Lexus/Toyota motor that could be 300k plus miles if you treat it right.
Here is my 2nd oil change done @ 3200km. I don't have the first one as the dealer service was incompetent and did not take sample. Even though the request was made and the container left on the seat...sigh.
There’s something about the V8 that causes owners to obsess over their oil. I’ve seen on the 5th Gen Camaro forums and BMW forums when I used to have those cars. Same story. People changing their oil, pouring over each line from their Blackstone report, worried, questioning, debating decisions - all for what? It’s bizarre.
My two cents, as a moderator, is that you do not have to be in this thread if you do not think oil analysis reports are interesting or useful.
Notice that some of the owners are just conscientious owners, while others are aware that they're using the car in a performance driving setting and simply want to see whether the oil they're using is up to the task. Nothing wrong with either.
I had an oil change done at 1300 miles and have done another 1K since then. Visually, the oil on the dipstick has been clear like water every time that I checked it at 32, 1300 and 2300 miles. Was this common for you all as well? I never checked the oil in my previous cars when they were new so I'm hoping that is normal?
Also, it seems to be a bit overfilled. The picture below was taken at 2060 miles but the oil level was the same at new,1300 and 2300.

Reason: typo
Ive been using the OEM oil in my IS500 and was interested to see how Exxon Mobil has updated it over time with every new API standard. We all know that the path of least resistance and cost would be to leverage the oils they already have and the consensus on older oil threads was that TGMO was most similar to Mobil Super 5000 +/- additives.
Interestingly, I got a more current SDS sheet for TGMO 5w-30 (last updated Summer 2024) and it shows a different formulation than the older TGMO 5w30 SDS sheets that are posted across forums. Google searches imply that CAS 848301-69-9 is a GTL base oil which could imply that this is more of a synthetic blend than a conventional oil. For whatever its worth, that same CAS number shows up in other Shell/Pennzoil synthetic SDS sheets. I've assumed the oil was a synthetic blend but there is nothing on the bottle that definitively tells you that.
All that to say that I think the OEM oil may have been intentionally (and silently) improved for 2URgse cars. I'll try to get an updated SDS sheet when the API SQ standard goes into place to see if it still looks the same.
