Chevron and Shell both hold the technology to make group II's, but unlike Chevron who is totally running with the group II and III technology and licensing it to others too, Shell doesn't seem to do anything with it. I have heard that perhaps they use it in there aviation oils, but all there earth bound oils don't use them at all. So no, Rotella is a conventional group I oil, flaws and all. I used to really like this product, but when Chevron became availible in my area, I switched to delo. I could get it cheaper and it was a better product. Castrol, Esso/Exxon, mobil, quakerstate, shell, and texaco, Kendal, and pretty much everyone else use group I oils in there conventional products. Castrol switched to the Syntec 'synthetic' to using group III oils to save some money ( didn't lower the price on the product though ). It used to be a group IV/V (pao/ester) mix, like mobil 1 and others. Only Chevron, Petro canada, and Pennzoil right now produce Group II and III oils for there conventional oils.
