Crower ZDDPlus motor oil additive is designed to add an adequate amount of zinc and phosphorus to protect your engine. It protects by creating a film on cams and flat lifter contact points in response to the extreme pressure and heat at the contact point. The film of zinc and phosphorus compounds provides a sacrificial wear surface, protecting the base metal of the cam and lifter from wear. Add one bottle of Crower ZDDPlus motor oil additive to each 5 quart oil change and your classic engine will have the right amount of zinc and phosphorus in the oil.
