2025 OT Oil Change $191 expensive? (1 Viewer)

I almost 99% guarantee you those prices don't include Toyota Genuine 0w20 oil, but that's not necessarily a bad thing (especially given the shearing I saw in my oil analysis). Just know that it's likely to be some aftermarket brand oil from a drum.

There is no way you sheared the VI improver in thenTGMO. It’s more stable than the base oil itself. You may have fuel dilution.

You might be right - I'm still learning about how to read and interpret UOAs and the vast, deep well of tribology knowledge.

Here's a link to my UOA: 2024 GX Engine Recall?

I see <1% fuel dilution, but 6.97cSt KV100 measurement after just 4100 miles. That's just barely in 20 grade, and I've seen a number of UOAs online where it sheared below 6.9cSt - for example, this 24 Tacoma UOA that sheared down to 6.2cSt which would technically be a 16 weight, I think.

This is 8 bottles of Toyota branded 0w20 I bought from a dealer parts counter in September 2025, filled at 816mi and drained at 4962mi.
