We blend VP Classic SAE 20W50 Non-Synthetic Racing Oil with high-quality mineral base stocks and a select balance of additives. As a result, it delivers superior film strength and wettability of critical engine parts while running or idle. The VP Classic blend contains a unique base oil cut that clings to engine parts and enhanced levels of zinc and phosphorous (ZDDP), which affords additional wear protection to flat tappet/roller cams. Furthermore, our Classic 20W50 oil features a robust detergent dispersant package and aggressive rust and corrosion additive to protect engines that run excessively hot and create large amounts of moisture at shut down. Whether its on or high-performance off-road applications, this blend is suited for dirt, mud, circle, and drag race engines. Its also great for classic car applications that require a 20W-50 non-synthetic racing oil.
