Careful. A "formulated for our earlier model cars" tag is pretty vague and no guarantee of it having ZDTP (zinc di-thiophosphate) in sufficient quantity. Better scope out the bottle's label closely. http://www.penriteoil.com/uk/nextpage.php?navlink=Zinc%20in%20Engine%20Oils is an interesting overview from a British company, with US and Australian distributorship. (BTW, they advertise that their Penrite HPR 15, Classic HPR, Classic 20W-50, Shelsely and Heritage oils all contain zinc, FWIW.)
