I will be changing the oil in my wife's 2012 Escape 3.0 soon. I have been using 6 qts Royal purple 5w20 and various filters so far. I have heard a lot of good things about Pennzoil Platinum recently, and while at walmart I noticed that it is considerably cheaper than RP. I know one of these threads went around a couple years ago, but what is the final verdict? I used the RP because of the synerlec and have always had good luck with everything RP, but if PP is the same as or better than the RP I'll save the $12 and go with PP.
