Royal Purple engine break-in oil

[whitehot1]

It looks like it has all the additives allready added to help the cam / bearings survive the initial start-up.

Any thoughts from engine builders or from those who have first hand experience with using it to do a break-in of their new engine?

Does it mention for use with flat tappet cams or not?? If not you need
to ask that question!

Yes it does mention it's for flat tappet and roller engines.
