Wanted to check opinions on these 2 oils --
IIRC Supertech is a group III {correct me if I'm wrong], a highly refined dyno.
Anyone know about the Valvoline...is it group III as well or group IV? I searched but didn't see a comment on it.
I'll probably go with the Valvoline, since it's only $3 more per 5 quart bottle.
