Sludge, a byproduct of oil oxidation, can thicken and build up in the engine causing increased friction, lower fuel efficiency and excessive heat. Older engines are also susceptible to oil consumption and oil leaks.
Until 1965, there was no high-performance racing oil. So we engineered one. Specially designed for pushrod and flat-tappet engines, Valvoline VR1 Conventional Racing Oil includes friction modifiers to boost horsepower at high RPMs.
