I dont know specifically. Ask the guys at bobistheoilguy.com. But with options like GC, amsoil, redline and royal purple and even M1 0w40, why bother with anything else? There are already lots of proven oils out there that show great analysis results.

^^ agree with Guits all except the Mobil1 and RP. 0w30 Castrol Syntec (black and red case usually in Autozone) is top notch, amsoil euro 5w40, redline 5w30 all top notch. Royal purple racing oil is excellent too, but mobil 1 and RP 5w30 are watery thin, kinda like having a nice bowl of hot thick chili and someone just pours a thing of water in it.

Mobil1 in 0w40 as well as their 10w40 SUV blend both are MUCH thicker than their 5w30. They also have good oil analysis results. But if youre unsure which ones are the good ones, best to stay away from M1 or you will get that watered down chili

As long as it has the API "SM" performance designation on the container you will be good. To meet these performance standards, said oil must fit very tight tolerances, thus making all oils with this designation almost equal.
