break in oil and changes

This is simple. Use Lucas brand motor oil. it has 2400 ppm of ZDDP. It's called "Hot Rod Oil" and comes in all the popular weights/grades. You can also add the Lucas zinc additive, although totally not necessary. This way, you have ZDDP in the OIL and it's not added. Lucas has all the right additives for use as a break in or everyday oil. I run it myself.
