I got this email Sunday, but it took a few days to put up a single link with all oils. The Mobil 1 0W-20 HM I just drained out of my engines looks pretty solid with the lowest NOAK and beefy add pack. Enjoy!

Leading or just a selection of 5? Seems strange that 4 out of 5 are HM; would have expected all to be or none to be in order to compare.

Thank you for the link. Here are the Noack x CCS values -- the lower the product, the higher the base-oil quality. Mobil 1 has by far the highest-quality base oil and Castrol has the lowest-quality base oil as usual. However, Castrol 0W-20's base oil is still fairly decent -- other Castrol viscosity grades (except Euro grades such as 0W-40) tend to be near the bottom in base-oil quality, using the cheapest Group III base stocks. Super Tech HM 0W-20 has surprisingly a GTL or a Group III+++ base oil.

Code
Noack x CCS rating

(a lower value indicates higher API base-stock groups
and/or a higher base-oil (not finished-oil) viscosity index (VI))

1. M1 HM 0W-20: 51,100 (GTL + PAO + AN)
2. ST HM 0W-20: 56,500 (GTL or Group III+++)
3. PP HM 0W-20: 56,800 (GTL or Group III+++)
4. Valvoline FS HM 0W-20: 61,500 (Group III+)
5. Castrol 0W-20: 62,100 (Group III+)

Wow, phosphorus (P) in the PP HM 0W-20 is low -- 560 ppm! When did that happen?

ST HM phosphorus is not looking good either.

M1 HM TBN is strong.

Castrol add pack looks strong, with moly, titanium, and boron, and it's low in calcium for TGDI engines.

I take this with a grain of salt because I don't trust PQIA testing...

Maybe that’s what settles out in the bottles? shrug

I bought a bunch of Valvoline Synthetic Maxlife 0w20 last month and am glad I got it on the cheap now. Nice strong add pack FTW
