what is best breakin oil for new motor?

the rotella has the zinc cut way back too. its only the old bottles that still have the high levels of zinc. I am breaking my engine in this coming weekend and just picked up some of the brad penn break in oil. it is designed specifically for cam break in. it was only 6 bucks a quart. i would pay 20 bucks a quart if that is what it cost. now is not the time to cheap out on the break in oil and lube. it could cost you a rebuild. i spoke with several race engine shops in my area and 2 of the 3 recommended this specific oil. most speed shops carry it. that is just my two cents. i have also read that too much zinc in the oil is a bad thing. if you run a high zinc oil along with a zinc additive it can be detrimental. wish you the best of luck my friend. starting a new engine has to be one of the best feelings in the world.
