I was wondering if anyone had any knowledge of Quaker State Synthetic Blend 4x4 5W30 and/or "Q" (Quaker State) Hi RPM Syn Blend 10w30? I have a chance to pick some up and wondered if is was any good.
Update: well I bought both of the older QS Hi RPM syn blend 10w30 and the QS 4x4 syn blend 5w30 oils. The Hi RPM is in the van and doing well. The 4x4 is in the Escape and I can't stand it. Noisiest oil I've used in her.
