I think all we can say for sure is that it is under 15% loss as a SN+/GF5 oil!
I don't see it on the d1G2 list as of yet, that would tell us it's under 13% loss.
When PPPP and PUP first came out, I remember that the former had about 10% Noack loss and the latter was about 11% for the 5W30s.
Those results disappeared from the SOPUS website before very long and I've never seen updates from the manufacturer.
Seemed strange to me at the time that the "premium" product had the higher loss, but both were good results and the PPPP was quite comparable to M1 5W30.
PPPP was on sale at Pep Boys with a $15 rebate card, so I bought a jug of 5W30 for my next change (which is coming up very soon). Don't shop there a lot but they have a location that is convenient for me and I stopped in after I saw the sale ad. M1 was just a bit higher with the same rebate and I thought I could double up with the XOM rebate, but the guys at the desk told me the $15 was actually from the manufacturer and I wouldn't be able to get both...made sense to me so I went with the SOPUS product, it's functionally identical to M1 5W30 as far as I am concerned.
