Again because they "recommend" (marketing agreement) Mobil, where they will use cheaper base stocks with 10W-xx oils.
Right, tell that to people who use 0W-40 oil in their track or rally cars. People who know oils know the difference between generic terms and real high performance oils."High performance" is a generic marketing term that is sorta meaningless IMO.
Most 0W-anything oils are aimed at fuel economy, not performance, longevity, or power production. (Excluding drag-race specific, ultra low viscosity oils that are meant to survive a single quarter-mile.)
Who says that?
Everyone who knows facts?
You'd have to ask them. I think the main reason is that with such a high amount of PAO and ester, it will automatically qualify for a low winter grade. Their PCEO line has group III oils and will have more VIIs.
I don't have an idea what are you talking about. He uses that same Mobil 1 Euro 0W-40 in another car.
I can tell.
0w-40 Mobil 1 begs to differ…"High performance" is a generic marketing term that is sorta meaningless IMO.

The winter rating has little to nothing to do with fuel economy. The only time a 0W rated oil is guaranteed to be thinner is below -35 or so. Fuel economy is overwhelmingly related to the operating viscosity, not the winter rating."High performance" is a generic marketing term that is sorta meaningless IMO.

That is accurate in theory, wrong in reality.
I don't understand that. Redline is not using inferior VII.
I corrected my post, the version you quoted was misleading.
Okay so then they are all 40-grade oils at operating temperature, and not below grade because the VII are incapable of performing properly.
Comparing the viscosity delta between two oils, grade information is not all that relevant for someone sophisticated enough to be BITOG member. Grades are a window, not a set visosity figure. Two oil in the same grade can have a wider viscosity difference than 2 oils of different grades. I am surprised you missed that
Yes true, at least to the precision that a PDS of typical values might indicate. However, if you really think those minor differences can be subsequently observed in some operational context, then I would suggest that is a fool's errand. Speaking of fuel economy, within a laboratory with controlled variables there is about a 1% difference between grades. Fine-tuning within a grade is even less relevant.
Is not that a common knowledge by now that those "controlled tests" severely under report the fuel savings? Personally I am even surprised 1% difference is possible on a steady state 2k RPM engine. I believe that comes from the Chevron study and unfortunately spread like a virus online by people repeating eachother rather than reading the source.
? I've read that paper, there is nothing in there that would invalidate anything I've said, much less validate your assertion that this fine-tuning within a grade would yield any substantive improvement whatsoever.
Okay fine, so it is better than 1%, at least for the oils they tested in their paper.
Because 10w-40 is not well suited to all climates.
Please, just read the paper. It is very well written. Considering how often you post on this forum, that can help massively by cutting the spread of misinformation around here.
