Should I switch to Mobil One EP for the PAO content? I've established, with some great help, that I am sticking with 0W-20 weight oil. Now I am wondering if it is worth switching from regular, full synthetic, Mobil 1 to EP for the added benefit of the greater PAO content? (I will still be doing oil changes at 4k mile intervals. That's just a "me" thing. I realize I could go much longer with EP or regular for that matter.) Since both oils in the 5 quart jugs at Walmart are about the same price, why not? Thanks
