Which groups do these oils contain??

Just curious, as I'm looking for a good alternative to Mobil 1 now. Which groups(mainly) are these common OTC oils?

Valvoline Synpower
Castrol Syntec(non GC)
Valvoline Durablend
Havoline(conventional)
TropArtic
Motorcraft
Mobil Clean 7500

Thanks.

group III: Valvoline Synpower, Castrol Syntec(non GC)
group II: Havoline(conventional)
group I-II/III blend: Valvoline Durablend, TropArtic, Motorcraft

Mobil Clean 7500 is either a group III/IV blend or a group I-II/IV blend depending on who you listen to.

BTW, Durablend and Clean 7500 are on clearance at AA. I don't know if they are discontinued or just discontinued at AA.

Havoline/Chevron 5w-20 and 5w30 are group II+
