M1 EP is better due to its high PAO content vs. Pennz Plat. Actually the best Mobil1 oil is now their Annual Protection (AP) version, not EP, and AP also has some PAO.
Avoid Motorcraft oil filters because they are made by Purolator, and they all have a reputation for getting a hole in the filter media. No kidding, this is a thing seen a lot in the last few years. Best oil filter is a Fram Ultra, the winner of most comparison battles when it comes to efficiency, cost, construction, etc.
How does it compare to Pennzoil Ultra Platinum?
Also, and not looking to start another oil battle, but I switched over to Pennzoil oils years ago, after using Mobil for years, as I consistently seen on here that Pennzoil oils received better UOA's than what Mobil oils did.
Mobil UOA's always seemed to have higher amounts of wear metals in them compared to Pennzoil oils. I am not sure that is still the case, but it was enough for me to switch over when I did, plus I could consistently find Pennzoil oils cheaper than Mobil oils, which, of course, was a bonus.
If you haven't read some of Doug Hillary's excellent posts, as well as his article on the value of UOA's on the main page of the site, I'd give it a read. You can't simply compare UOA's between oils to determine which one is "better". That's not the purpose of the tool, which is to determine oil life, contamination levels for condemnation limits, as well as to allow one to potentially glean some insight into machine health and indicate potential impending catastrophe.
Interesting, and I guess it's best I read it, but when I see elevated "wear metals" in different oil UOA's, I automatically think the oil isn't doing it's job as good as the other oil is. Elevated Wear metals, imo, when seen in UOA's, tell me the oil isn't lubricating/protecting as good as they should, especially when you see other oil UOA's that have "normal" or nil amounts of wear metals in their UOA's.
Like I mentioned, this was years ago, and the UOA's were based on the Mobil I was using at that time. Like I wondered, I am sure things have changed/improved some, especially with the many types of oils that are now available.
