I have no idea what the gravity of the correlation is between oil, in terms of performance, but is anyone finding out these turbo 4s, the performance in terms of the thrust kick just fantastic in terms of engine + oil and not just oil to the exclusion of everything else, like this site professes. Furthermore, isn't it just running any 0w-20 oil that they are prescribed and not even trying to be all elite about it. Mid 7s in cst @ 100, no problem! Average 2.4 or > HTHS, can do. No high moly VI so loving the VI in the 170s? No problem! No long drain intervals, who cares, I go by the monitor system.I mean, it NEVER ends, does it? These engines are what are the dynamos and super duper performers, not the oil, lets not get it twisted! (I'm running the Honda full syn 0w-20 and it is average at best so what is it, the chemistry *in the engine* and the operative words are *in the engine*!!) SO I guess it can be the Full syn Honda oil in conjunction with and I simply can't prove it but, so be it. Got me.
