Does Anyone Bother To Add Any One Of The Million Oil Additives ( I.e Stp,lucas Etc.) On The Market To There Oil Changes? Any Reason Choosing One Over The Other?
Thanks

Need zinc for aggressive cams. I add a half bottle of ZDDP Plus every time I change the oil in my 440. Just to be sure.
no, you need ZDDP for the initial break-in. once the cam establishes its wear pattern, zinc is not so much an issue.Hi You don't need adatives if you are using the right oil for the right application.flat tappet cams need zink phosphate.Most newer oils don't have enough. They lowerd the zink phosphate content to protect the catalitic converters.The raceing oils still have it and some of the high mileage engine oils do. their is a very good article about it at (classic car motor oil .com)sorry i don't no how to post the link but it is worth reading.

heres another interesting factoid. twice i've installed cams, no break-in, just started and went. never hurt them
and somebody will chime in sayin something about how ryan at shady dell said "you must do a proper blah, blah, blah" in 3, 2, 1..... LOL!I can back that statement up my builder laughs everytime someone mentions break-in period,we break in cams by running them not sitting there idling for 20 minutes at so and so rpms..the one in my stroker got broken in on the 1/4 at e-town..just make sure you use a GOOD quality oil and yes change the oil and the filter shortly after running the new motor to get all the assembling lube and any contaminates out..i use 15-40 diesel w half a quart of Lucas oil treatment in my motors and have for awhile now,to each his own..
