Although there's not necessarily a vast amount of information out there on it (like VOAs or UOAs) the PQIA entry below and some consumer experiences suggest Valvoline Advanced Full Synthetic may be one of the best PCMO products available on the market; if only based upon the numbers. I will share my experiences or UOA, if I pony up for one. Have any of you used this before? I'd be curious to hear about it. I'm surprised I don't hear or read more about it, but that doesn't discourage me. I was going to make this a "change my mind post," but it's already made up, because I bought it.
