Oil formulations are being changed mainly due to pressure from the EPA and secondarily from the factories switching to roller lifters. Zinc and phosphorus tend to coat O2 sensors and plug catalytic converters resulting in warranty claims as well as contributing to dirty exhaust emissions, so they are being eliminated from motor oils as we speak. These elements were used in the oil to provide extreme pressure lubrication and protection from galling on heavily loaded engine components such as the cam lobe/lifter crown interface. | Oil formulations are being changed mainly due to pressure from the EPA and secondarily from the factories switching to roller lifters.
