This is a 2012 Toyota Classic Prius 2 1.8L Gas/Hybrid. All oil change was done by Toyota dealership I am putting as type/brand what the invoice said at the time.

Analysis was done by BlackStone Labs for each

Not sure that your 20,000 sample was TGMO, as it's very light on Ca and Zn compared the TGMO VOAs.

The latest also "looks" better from a metals perspective, which confirms my suspicions that you got TGMO on the last change, but not the one before.

Your car has problems keeping the oil in grade (2 out, 1 so close, and the other quite close to being out of grade.

Hmm, your last two reports also look quite different than mine:

thanks for you comments ... again I double check the invoice but their is no way to know what they use other than what is written on the sheets ...

"problems keeping the oil in grade" what this supposed to mean ?? what shows "grade" and should I change earlier ???

IMHO, this only proves how inaccurate those results are. Waste of time and money.

new TGMO viscosity @100C is about 8.5 cSt. yours went down to below 7 cSt. a big jump below the range for SAE20 oil. however, no increase in wear as measured by this UAO (very crude method, though).

bottom line, nothing, just follow the official OCI recommendations.

Exactly - just follow the OEM recommendation (and don't exceed it). If you're uncomfortable, then reduce it...
