At -20F I poured the following oil; Pennz 5W30 Valvoline 5W30 Pennz High Mileage 5W30 Canadian Tire 0W30 Quaker State Winter Blend 5W30 They were all very acceptable but Quaker State wins, hands down. I tried 3 synthetics: Amsoil 0W30 Castrol Green 0W30 Mobil 1 0W30 Here Castrol and Mobil 1 win and the Amsoil did about as good as the Quaker State winter. You could say QS Winter Blend is made to flow and pour, and question other qualities, but for the price of $1.99/Qt (on sale) it's great if you don't want to go synthetic in extreme cold.
Thanks for the info! Granted pour points don't particulary relate directly to cold-cranking, it would be interesting to see a VOA and UOA of this oil as QS has a middle-of-the-road stigma 'round here.
Just bought the QS winter blend 5w30 API SL at big-lots for $1.88. Its viscosity index is crazy high at 207 and would like to see the Noack volatility % for this oil.
It's GF3 rated, so it has to be <15%. I have about 24 quarts of this stuff, that I bought last summer for c$2.49/qt I'll be doing a UOA on this stuff maybe next April.
