EXTREME RACING OIL 15W40 CK4 Heavy Duty motor oil is specifically engineered for diesel and heavy-duty gasoline engines that require robust protection under extreme operating conditions. This 1-gallon container is ideal for use in pickup trucks, commercial vehicles, and high-performance diesel engines that operate under severe service conditions.
The CK4-rated formulation provides professional-grade lubrication, ensuring reliable cold-start flow in winter temperatures while maintaining full film strength at elevated operating temperatures. This is particularly critical for turbo diesel applications, where sustained heat and boost pressure test oil durability. CK4 certification offers superior protection against soot loading, oxidation, and wear compared to older CJ-4 specifications.
Mechanics and fleet operators benefit from EXTREME RACING OIL's consistent performance across various diesel engine platforms, including Cummins, Duramax, and Powerstroke. The formulation is designed to resist breakdown during extended drain intervals, making it suitable for modern heavy-duty diesel engines with advanced aftertreatment systems.
