Ah thanks, so the results are comparable. Pretty amazing how low 0w20 can go these days. Would it be safe to assume that PUP has even lower Noack?

I've noticed that recent Noack tests from PQIA have been @ 245.2c instead of the ASTM D5800 standard 250c https://pqia.org/pennzoil-platinum-sae-0w-20-full-synthetic-motor-oil/ vs http://www.pqiadata.org/Pennzoil_Platinum_0W20_dexos.html Anyone know why this is and if the results could be...

Moly is over hyped, basically no difference.

Valvoline just sponsored a youtube video yesterday that says LOW NOACK is best for keeping deposits out of modern GDI engines. Other than that one sketchy Polish research paper claiming high NOACK is better, is there any other evidence backing up the theory?

10k miles if mostly highway, but not 10k miles of city traffic.

Run 0w30 in winter. 5w30 won't do your engine any good @ redline when it's cold.

This is definitely the trend. Take Toyota's V6s for example: 1MZ/3MZ 3.0/3.3L both are 5qt sumps. Newer 2GR-FE V6 3.5L = 6.4qts Corolla: 1ZZ-FE 1.8L = 3.9 qts 2ZR-FE 1.8L = 4.4 qts Camry: 2AZ-FE 2.4L = 4.0 qts 2AR-FE 2.4L = 4.65 qts I think a lot of this has been influenced by North American...
