Anyone in here use
Mobil 1 EP over Mobil 1? I presume any one who might be doing extended oil drain intervals are obviously doing so once they are past their 100K warranty. I am at 120K miles and run Mobil 1 5W-30. Am wondering if I can extend my current 5K oil change interval to 10K by switching to Mobil 1 EP, with the Mobil 1 filter?
