I agree that PetroCan is obviously working to optimize the low temperature properties. But, is it really a given that it follows this compromises the high temperature performance? The % of aromatics in the base oil from PetroCan is extremely low, and the flash point of the finished 0w30 product for example is very high, and compares quite favourably to the other PAO synthetics. Flash point is not everything, but it seems to be an indicator, that they are not using heavy amounts of VHVI 2 base stock (FP 177C, PP -42C) to get the low temperature performance. See data tables below.quote:

You can choose to really optimize the low temp propertes or the high temp properties, but not both. Petro Canada does the former; Redline does the latter. Most other synthetics like Amsoil and Mobil 1 are somewhere in the middle.
Your choice....
I do agree with the comments about pour point depressant additives and that they likely have a finite life. That may be the real story on the good group III oils at this point in time. On the other hand I've seen it noted in a few places including the original posted article in this thread that Group IV base stock has poorer solubility of additives, so that may limit what can be done for them as well.
