Help me group these oil brands

[Ironthinker]

I live in northern MN. When we have a -25f - 30f temp some night I'm going to invite some of my friends to my garage and have an oil pouring party.

I need help putting each of the oils in the proper group.

Valvoline Max LIfe 5W30
Pennzoil MultiWeight 5W30
Pennzoil High Mileage 5W30
Quaker State Winder Blend 5w30
Mobil 1 0W30
Amsoil 0W30
Castrol (German) 0W30
Formula 1 Extreme Winter Blend 0W30(MotoMaster Canada)
