Royal Purple is making a new "BREAK IN" oil that is loaded with that anti scuff stuff, suppose to be more of that "STUFF" than anybody else's.
Great news for flat tappet engines wanting a decent break in oil but really not necessary for soild rollers IMO.

Personally, I use castrol 20w50 it doesnt cost a arm and a leg and I have never had a oil related break down - I'm fixing to swith to a lighter oil since it's really cooled down here my area.
