Considering how much it shears (down to 40-weight during typical OCI), there is probably not a whole lot of PAO and esters in there.

Couldnt the shearing be purely related to the wide spread ? Penrite who have a full sin range of PAO and Ester admit their 0w50, 5w60 and 10w70 will shear down, where as their Sin 15w40 and 25w60 are shear free. The last 2 mentioned may even have GP3 as they dont describe it in the same way as the PAO and ester Sin versions. Mobil 1 5w50 is also a great shearer, people use it as if it was a 5w40 oil.
Thanks guys.
Thanks guys.

May be, but that begs the question, why bother buying a 10w-60 oil which will shear to a 40-grade anyway? Why not just buy 5w-40 or 10w-40 oil that's shear-stable to begin with?

Castrol tech line told me it's PAO as is the 0W40.
The question is, how much PAO?
hmm. They certainly have PAO and ester. But how much group 3 is another thing.
