Amsoil SS 0W-20 w/ Amsoil EA15K09 - 10022KM - 2018 Prius Prime

[OilyOrangutan]

Got my UOA back for my Prius Prime. Being a PHEV I doubt it even had 6000km on the oil. Boron was low OA claimed. However lots of TBN left and wear metals to my untrained eye don’t look to bad.

Comments and insights always appreciated.

Great engine/oil combo = great results.

Agree with @buster
Boron may be low for this oil but at 224 ppm it still has plenty left. I don't necessarily know what the starting oxidation is on this but it appears you could go 20,000 kms with ease on this oil. Stellar results!

It is normal for Boron to deplete with use. I have seen oils where the Boron starts in triple digits and after a significant run, is down in the double or even single digits. Out of my own UOAs, the most significant drop I've seen was from 298 to 97 (M1 ESP 5W30).

Very nice report. Will be posting my results in a few weeks on my RAV4 Hybrid. Hope it looks this good.
