Whether COP ownership is the reason I don't know.
I'd rather have a more modern additive system in some of RL's oils. Most cars on the road today do not need high levels of ZDP and in fact it can be harmful. (Not just emmissions but with certain aluminum). Also, the type of moly RL uses is not as good as teh trinuclear type.
From a marketing standpoint RL directs its efforts primarily at competition. As such they are not so concerned with catalytic converters in late model OBDII/high tier vehicles. The question might be could that role be better addressed by transtioning to trinuclear moly or titanium for instance? To do so might help render RL "me too" without gaining enough benefit from that change in the market.
As to base stock proportions/changes we BITOGers chase our tales a lot because we only conduct rudimentary spectrograhic analysis. Without further insight into product formulation many, if not most of these oils, are too similar to really matter or indeed to pick among them.
