Okay, I was wondering what you thought was better between Mobil 1 0w-20 EP and Pennzoil Platinum and Pennzoil Ultra Platinum. This would be for a 2013 Lancer SE with the 2.4L I also have a 2014 Fiesta with the 1.6L motor and It requires 5w-20. I would be interested in comparing the same brands/models of oil. from what I can tell on paper the 5w-20 platinum looks the best. Thoughts? I am currently running Mobil 1 EP in both cars. Both are under warranty so the Lancer gets its oil changed every 6 months or 7,500 miles and the Fiesta gets an oil change every year on 10k miles.
