   Engines with flat tappet cams will benefit from an oil with higher levels   
   of ZDDP.  As a consequence, many people with older cars use either an oil   
   designed for diesel engines with high ZDDP, or use an additive with extra   
   ZDDP.  This was discussed extensively in this group twenty years or so back.
