Fiat-Chrysler must do some consolidation, particularly given their partnership with Shell. Whatever you do, don't go to the Shell data sheet website and look up the entire catalog of 40 grade Pennzoil products. There's a reason why, when I mentioned elsewhere that NAPA Canada is advertising Pennzoil Ultra Euro 0w-40 and 5w-40 in the EcoBox, I said, "whatever that means," noting that could be two oils of like four or more choices, between not knowing which version, whether or not it really is Ultra or Platinum, not to mention how old the stock or labeling might be, either.
