Preheating Joe Gibbs break in oil to 180F

I've never even imagined doing this LOL. Maybe I just lack imagination.....Used Gibbs break-in and just ran it at room temp. Honestly, I think the type and quality of the cam lube is the key things. Moly paste only for me...

I understand the zinc isnt active until a certain temp. Or something to that effect???

My understanding from repeated readings of scientific descriptions is that it is pressure that primarily promotes the formation of ZDDP protective films. And I've seen nothing saying it simply won't work at much lower temps; just that it forms a film faster at some higher temps.

Which makes me wonder if part of the beneficial reason to keep the RPM's up is to get the oil temps up and speed up the ZDDP action.....???? Hmmm....
