Is Mobil 1 EP just Mobil 1 with better additives?

I always have used PP or Quaker state syn in the 3.5 V6(30K miles) and Mobil 1 HM and regular Mobil 1 in the 3800 V6(70K miles)and never had an issue using oil between OCI's. Both the 3800 V6 and the Hyundai 3.5 are usually easy on oil. What's up with EP? I'm thinking about draining both and going to PP...


If your newer cars are using oil at that rate, it means there are engine problems. Switching to Pennzoil Platinum does not magically make engines stop using oil.


+1. There is no magic oil that transforms engines. However regular M1 protects as well up to 10K as EP. EP is designed to last longer so that's why reg M1 has a 10K warranty and EP has a 15K warranty. Even with that said I know several that go much longer on reg M1 than 10K some up to 20K OCIs. Here is a link from XM that explains this.

It should possibly be noted as well that Mobil 1 0w40 is probably equal or better than EP. They just don't have two products in that category.

I use M1 5w30 EP in my F150 Ecoboost.

For what ever reason, possibly fuel dilution, the truck idles roughly when an oil change is due. Seems to at less than 7000 miles fairly consistently. Even though the oil change monitor shows plenty of life left.

So, I change the oil, and instantly, the engine idles smoothly, and is quieter. In my case, EP oil makes no difference. I've use other brands with exactly the same result.

I mentioned PP, etc because EP seems to suck in these engines(I'm usually a Mobil 1 fan). These vehicles have never went through oil until I did OCI's with EP for both in the last few months. I know engines and been around them for 30 years, this seems to be a oil quality problem... Weird that both need oil added when they NEVER used oil before. Back to plain jane Mobil 1, Mobil 1 HM or PP...

Does ExxonMobil guarantee regular M1 to 10,000 miles like they do for EP to 15K?

Never heard of an engine idling rough when an OC is due?
