Racers have been depending on Valvoline for more than 100 years. Valvoline formulated the first racing motor oil in 1965 and Valvoline VR-1 Racing Motor Oil is the best-selling motor oil of all time. It can also be used for today's cars.What are the benefits to using a racing oil versus a regular "street legal" oil? The Valvoline VR1 Racing and "Not Street Legal" Racing Oils contain additional additives for increased horsepower and reduced friction on metal parts, provide extra wear protection for high compression/higher horsepower engines, and include less detergents than regular conventional motor oils.What is zinc? The anti-wear additive simply referred to as "zinc" by most car enthusiasts is actually short for Zinc DialkylDithiophosphates or ZDDP. 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.What solutions does Valvoline offer to the zinc issue? Valvoline offers two solutions to the zinc issue: 1. Valvoline VR1: Contains 75% higher zinc than SM motor oil with a balanced additive package designed to work in both racin
