Your engine is different being port and direct injected at the same time. 2GR-FKSThanks for the reassurance, but, look at this UOA.

Many of the UOA of the Toyota 3.5L look nothing like mine. My numbers are shocking. This oil looks like it could be the factory fill and has never been changed.
I understand your concern but break-in wear is going to vary from truck to truck. The long term trends may be more similar between other Toyota's. You just can't compare them yet.Thanks for the reassurance, but, look at this UOA.

Thanks for that info cptbarkey, I didn't realize my engine was selectively using direct and port injection. That will probably be expensive someday if it needs fixed. I'm getting the oil changed one more time at the dealer next week since Blackstone noted the TBN is 2. Then I will begin doing my own OCi.Your engine is different being port and direct injected at the same time. 2GR-FKS
It doesn't really have anything to do with assembly, just better machining by this logic.I’m a firm believer that you can tell how good an engine was assembled by analyzing the first few oil drains.
No it does reflect on assembly, esp regarding tolerances and tolerance stack issues.It doesn't really have anything to do with assembly, just better machining by this logic.
I'm a firm believer you cant tell anything until about 75k. have an engine wears over time will tell you how good of an engine it is. the best engines a designed such that the surfaces mate and wear drops to nothing.Imagine had you not changed the oil until 10k on the factory fill…
It still seems like a lot of metal shedding during “break-in” regardless of the fact that it’s a “young” engine with less then 60k miles.

Actual engine parts wear in happens within the first few HUNDRED miles at the most. All subsequent oil changes should see decreases in metals since no more is being produced and it’s washing out.
After 3 oil changes, no break-in stuff should still be there on a good healthy engine, in my opinion.
Whats ESP?No it does reflect on assembly, esp regarding tolerances and tolerance stack issues.
