Trying to find the Pennzoil ultra for my 6.4 I have checked every parts house in my area, researched extensively on the inter web and cant find anything else that meets the ms-12633 spec. I think I will just use mobile one full synthetic until the Pennzoil becomes more available. My only other source is Amazon and it would be cheaper just to have the dealer change it. Any thoughts?
