Its primary role is to prevent metal-to-metal contact between engine parts by forming a protective film. Despite being referred to as "zinc," this additive actually contains zinc and phosphorus, with phosphorus performing the anti-wear function.Why have the zinc/phosphorus levels in motor oil changed?With ever increasing limits on emissions, automobile manufacturers have tightened emission control systems on newer vehicles. This is one of several factors considered when the American Petroleum Institute (API) sets standards for motor oil. The current API standard is "SM" which replaced the previous "SL" classification. Because phosphorus can poison a vehicle's emission system, the level of zinc is lower for current motor oil.What is the controversy surrounding the amount of zinc in motor oil?Many hands-on car enthusiasts and engine experts believe the lower levels of zinc in "SM" motor oil is causing excessive wear in older style push-rod and flat tappet engines. This is despite the fact that all new motor oil classifications are intended to be backward compatible. This has resulted in the widely accepted belief that modern motor oil is not adequate to protect older engines.Which oil has more zinc/ZDDP: VR1 or "Not Street Legal" oil?Valvoline VR1 Racing Oil contains .13% of Zinc and .12% of Phosphorus compared to the Valvoline "Not Street Legal" Racing Oil which contains .14% of Zinc and .13% of Phosphorus.Can I use an additive to boost the zinc level?You can use an additive to increase the zinc level. However, check with your motor oil manufacturer to ensure the additive is compatible with your motor oil.
