I have a 2021 Toyota Land Cruiser that I purchased brand new with around 5 miles on it. I changed the oil once at 750 miles with a OEM Toyota Filter & Mobil1 0W20, and second time at 10k with the same filter & oil. I recently drained the oil and took a sample from the oil that had roughly 9000 miles of use on it and sent it to Blackstone, the reports and their comments seem to show abnormal wear. I am hoping that this is all still just break in metals and will get better or level off with time. I am not too concerned about it as it is under warranty & I have no plans to sell it but thought the folks here might find it interesting.
