The ford spec doesn't really matter, the ILSAC is the only requirement for warranty, and any oil that has the latest GM Dexos spec will far exceed anything that Ford's spec has to offer.Thank you for pulling that chart up for me. I am not most computer savvy. My concern is the WSS-m2c961-a1 specification. When I go to Pennzoil's website and type in2022 F250 ultra platinum is not listed.
I do not want to give them any opening to be able to wiggle out of the warranty.Mobil 1 EP 5W30 meets the current Ford spec. stated in the manual. There are others too. For whatever reason Pennzoil caters to GM not Ford.
Unfounded fear. If it has decent looking oil in it and there is a mechanical failure, they wont bother you.I do not want to give them any opening to be able to wiggle out of the warranty.
