not to sound rude, but who cares? that looks like a waste of time anyways. It's like having a website about air filters, or a website about drinking water.
Sure motor oil is important, but unless you own a nascar team, i cannot see what harm using valvoline oil over mobile one will cause. Personally i used valvoline in my infinity G20 w/a j-spec SR in it, and it ran great!!
