As for VI, I am getting tempted by the Delvac Elite 222 0w-30. It's at least in 5 gallon pails, which I prefer. If I do get around to getting some, should I pick you up a pail of Delvac 1340 while I'm at it?
M1 0W-40 out spec's Castrol 0W-40, so unless it can be had for a lot less (it can't) M1 remains the better deal on both sides of the border.
I was a fan of Esso's XD-3 0W-30 which they made a point of declaring it was PAO based but I'm uncertain about Delvac Elite 222 0W-30, and it's PP of "only" -45C makes me wonder if it's MRV is anywhere near as impressive as XD-3s 14,900cP.
If you are serious about picking up some I'd try to get the MRV spec's out of Imperial Oil and for ESP 1 0W-40 while you're at it and whether they are still PAO based?
I tried a couple of years ago but got a rep' that simply told me it's unavailable simple because it's not on the PDS. The info is available as it is for all Mobil oils, it's just a matter of getting hold of he right person in the know.
In your climate where MRV is relevant I would think someone, even a knowledgeable Imperial Oil depot salesman, should have the answer.
