Being a proponent of "Can't hurt / Might help", can you suggest a brand and item for a ZDDP additive?

These two are available at my local Advance Auto Parts:

> Rislone Engine Oil Supplement (11oz) "1996 and older - Add one bottle to crankcase."

> Lucas Oil Products TB Zinc-Plus Engine Break-In Oil Additive (16oz) For break-in, change after 1,000 miles. Add full bottle to crankcase for older cars.

How much to add to crankcase? Alvin's engine rebuilder suggested 4oz. of a 12oz bottle.

Thanks,
