Here's a UOA of the new Conoco Phillips made Honda Genuine Ultimate Full Synthetic 0w20 (API SN), including viscosity index.
I previously did a VOA on this very batch of this oil here.
This oil started out quite thin and then sheared about 10%. This time Blackstone didn't forget the VI measurement and it came back at 175 which is about what we believe the virgin oil was. It's good to see that the VI remains high even after some use and shearing.
I'm not really concerned about the high Al in this UOA, if it persists in the next UOA I'll start to worry. I won't be continuing to use this oil, it's expensive, hard to find and offers no benefit over the readily available M1 AFE 0w20.
The oil was changed with API SM Idemitsu 0w20 from Subaru which I believe to be the same as the old API SM Honda Genuine 0w20. We'll see how that performs.
The other UOA on the sheet is the factory fill. Enjoy.
