Lots of reviews concerning M1 and Castrol 0w20, but not much involving Valvoline Synpower. Based on the numbers below, and my ever so slightly, better understanding of what they mean (thanks to many of you), Valvoline's version appears to be comparable. With one caveat, the MRV #. I'm assuming it is skewed, correct?
