Not wanting to start any filter wars, just want to know if anyone has heard of these. From what I can find, they are a Pennzoil product. Here is my dilema, purchased lifetime oil changes from dealer(Lithia) when I purchased my truck. Took it in for first oil change and they used a Performax Oil filter? Previous truck I did my own oil changes and used only Fleetguard filters and Rotella oil. I would have thought a dealer would only use OEM Mopar parts?
