VP Racing CI1 Hi-Performance SAE 5W40 Synthetic Diesel Engine Racing Oil

VP blends this SAE 5W40 synthetic oil for diesel racing engines and towing applications. Our high-performance full synthetic blend features premium high viscosity-index synthetic base oils, which provide excellent high and low-temperature protection for diesel race engines. Secondly, VP adds enhanced levels of zinc and phosphorous (ZDDP), an aggressive detergent dispersant, and an anti-oxidant package to our 5W40 synthetic diesel oil. This protects against oil thickening and diesel engine deposits.

Multiple engine builders, including Al Moody Race Engines, have performed dyno tests of VP’s engine oils. They have documented real horsepower gains. Additionally, many of these same engine builders have performed documented video teardowns to inspect wear on engines. The engines ranged from 355 cubic inch dirt track motors to 3,000hp big block marine engines. Upon inspection, engine internals look virtually new and they can reuse them beyond traditional replacement intervals.

When 2nd place isn't good enough, trust VP 5W40 diesel engine oil for your racing and towing needs. For the ultimate winning edge, be sure to try VP TORQ DX Diesel. Several tractor pulling series use VP’s diesel race fuel as a spec fuel. It offers a consistent product racers can rely on.
