Interesting.
Will consider it. Have had goid luck with Magnatec so i hesitate to change from that.
Magnatec is step below Edge, or two steps below. If you go Castrol, go Edge.
Mobil1 EP 0W20 has hefty % of PAO, which would be better in cold. If I was about to live there, and needed these ILSAC-GF5 oils, I would go Mobil1 0W20 EP.
Redline is really good since it is Ester, and will do good in col. Pour point is irrelevant. Pour point is relevant to figure out base stock. Low pour point indicates synthetic base stocks. However, it really does not matter for starting purposes whether it is -76 or -60 or -50. Your oil will not use gravity to move. Oil pump will do that job. So, CCS and MRV performance is what matters to get picture which oil will do better.
However, there is no doubt that synthetic 0W20 oils will do job. I would be more concerned with heat, battery etc. Block heater is minimum and trickle charger for battery. Also, maybe bumping battery capacity.
Found this article to be very helpful.

If you know how I can get the gelation test on various oils, I would be greatful. Meanwhile, pour point is a legitimate test that I do have access to. On Edge vs Magnatec. Edge 0w20 pour point is -42°C vs the Magnatec -51°C is a significant difference. What I don't know is the curve of the viscosity. Does the Magnatec thickens up way early but then flattens out? That would make it a bad oil for extreme cold.
Red Line is some nice oil. But it would be cheaper to put on a heat pad....alot cheaper lol.
Again, pour point is legitimate test, it is there for a reason. But do not get stuck on that. I would go Edge any day over Magnatec in any environment, not to mention such harsh environment.
Though, when it comes to those ILSAC GF-5 oils, Mobil1 0W20 EP would be my choice.
Also, new Euro 0W20 oils have much more stringent approvals than these oils we are talking about. Obviously you are not looking cheapest, so oils such as BMW TPT 0W20 would be good choice, or anything that is MB229.71 approved.
