I know Pennzoil Ultra was highly regarded and recommended, but I haven't heard much about this new formulation other than the NOACK increased dramatically (from about 5-6% to 11.5%). I don't know much about NOACK and why it matters as I'm still new this stuff, but do we expect the PUP stuff to be as good as the original Ultra?
So are you saying that the formulation of the old PUP in the black'ish bottle is
different than that in the new Yellow bottles?
I still see some of the black bottled PUP - which is obviously old stock on the shelf.
We have started getting a good supply of the PUP up here in Canada, but only at 1 major retailer (Canadian Tire). Walmart only carries Pennzoil Platinum as their premium pennzoil oil.
The Pennzoil Ultra Platinum hasn't changed formulas from the black to yellow package to the best of my knowledge. The difference comes in the naming convention Pennzoil Ultra Platinum with pure plus technology or as we generally refer to it as PUP or PUPPP is GTL base stock. Then there is Pennzoil Ultra (no platinum in the name, no mention of pure plus technology or GTL).
I'm not arguing that it changed forumlation going from black to yellow bottle because I have no idea, but why would the dark gray/black bottle have the DEXOS approval on it and the yellow bottle not if the formulation is the same? I'm honestly asking because I don't know if the DEXOS approval is something that has to be paid for yearly or if it is a one time cost whenever you change formulation.
