hi guys,
I just finished watching a shocking 30-min video shot at precision Z doing an independent study (shoot out) between several different Motor Oils and Additives.
They tested Castrol Syntec, Mobile 1, Penzoil Platinum, Motul, Nippon, Royal Purple, and Enios. There were also MOA and Lucas additives tested.
The results was Royal blue and Enios were the best performing with over 10lbs of weight, few quart-bottles on top of the weight, and the oil pan removed. There was very little wear on the bearing.
The next test was all oils with MOA and Lucas additives and MOA made a Huge difference in all the test. When tested with Royal Purple and Enios, it blew everything out of the water including a IRON rod on top of the wait. There was almost no wear.
Among the worst was, Motul, castrol, Mobile1, and Penzoil.
The best performing was Nippon, Royal purple, and Enios, hands down. I think they concluded that Royal Purple with the MOA was the best.
I've used Mobile 1 ever since I bought the FX in 2005. I thought that was a great products, but now, $8 a quart for Royal Purple sounds great.
