Not necessarily about the Pro Stock contingents but if I felt like I needed to add something to the oil I was using I would get a different oil.

I see the normal guys talking about adding zinc to break in oils when in reality too much zinc is an abrasive.

True, but when breaking in a flat tappet cam, you don’t need to add zinc, you just need to run oil with the right amount already in it.

I know, but I took it they add zinc to oil that already has the correct amount. And I agree that too much can be harmful.
oh you absolutely took it correctly then. I keep seeing guys suggesting adding ZDDP additive such as Comp Cams sells to break in oils. I don’t get it. I guess the old adage, if a little is good more is better.
