AMERICA’S #1 RACING OIL is recommended for high-performance gasoline engines as well as those burning full or partial alcohol fuels
FULL SYNTHETIC FORMULA is engineered specifically for modern and classic high-performance engines both on and off the track, which includes flat-tappet and performance cam motors
SPECIAL FRICTION MODIFIERS help minimize friction, keeping heat at bay for maximum power and torque at high RPMs
2X MORE ZINC FOR EXTREME WEAR PROTECTION for even greater film strength and anti-wear protection on critical engine components such as pistons, cams and bearings
"Great oil!! This blue oil was just what my Jeep needed. The added Zinc and phosphorus was perfect for my AMC 360 motor. Synthetic that flowed smoothly even in cold weather, with added protection during higher temperatures."
~ John
The Valvoline VR1 Racing and other racing oils not intended for passenger vehicles contain additional additives for increased horsepower and reduced friction on metal parts, provide extra wear protection for high compression/higher horsepower engines, and include fewer detergents than regular conventional motor oils.
The anti-wear additive simply referred to as zinc by most car enthusiasts is actually short for Zinc Dialkyl Dithiophosphates 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, ZDDP also contains phosphorus, which helps to perform the anti-wear function in the motor oil.
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 with zinc. The current API standard is SN, which replaced the previous SM classification. Because phosphorus can poison a vehicle's emission system, the level of zinc is lower for current motor oil. Valvoline uses a new type of zinc/phosphorus that maintains the prior level of wear protection of the engine while reducing the impact on the emission system.
The controversy exists as a result of many hands-on car enthusiasts and engine experts belief that lower levels of zinc in API SN and SM motor oils can cause excessive wear in older style push-rod and flat-tappet engines. They hold this belief despite the fact that all new motor oil classifications are intended to be backward compatible.
Keep in mind that zinc additives are corrosive above certain levels and can harm your engine. Valvoline doesn’t recommend using third-party additives to boost the zinc level. If higher zinc levels are required for your engine, we recommend using Valvoline VR-1, and always remember to consult your vehicle’s owner’s manual.
Valvoline offers two solutions to the zinc issue: Valvoline VR1 Racing Oil: Contains 75% higher zinc than SN or SM motor oil with a balanced additive package designed to work in both racing and traditional applications. Valvoline provides this product in both multi and mono viscosity grades: 20w50, straight 50, 10w30, straight 30, straight 40 and straight 60. Longer-Lasting Zinc/Phosphorus: Valvoline uses an advanced zinc/phosphorus additive that keeps higher levels of phosphorus in the motor oil where it protects the engine instead of poisoning the catalytic converter.
