[Healeys] FW: Castrol Syntec

[Warthodson at aol.com]

There seems to be a conflict here. How can Castrol Snytec 20w50 be rated  API 
service SM & also have the higher ZDDP levels of earlier service ratings  & 
the higher ZDDP levels required by classic vehicles with flat tappets? 
Has anyone received a direct reply form Castrol concerning this?
Thanks,
Gary Hodson
