Valve jobs, and oil

["Ron Fine" <RonFineEsq@earthlink.net>]

Can I get some clarification:  I read the earlier posting and I replaced my
break-in oil  (after the first 700 miles)  with Chevron  Delo 400 which is API
CI-4 PLUS rated.  Am I correct in my understanding that this diesel oil should
have enough ZDDP to protect my new valve tappets??  Do I still need to add the
GM EOS product to this oil??
