Pretty sure that part of the rotella thing has changed, theres a thread or two around about it, it was the zinc that helped with things, and due to most new diesels even having catalytic converters, and the zinc damaging them, its been removed also, apparently the old guys stuck to flat tappet cams used to be all over the stuff.
Its still quality oil, and usually $10.50/11.50 at walmart, and each of mine did just fine on it till the oil pump pickup didnt help get the shit into the pump...
Current motor will also live on rotella 15/40 and pureone filters
