SR-1 Synthetic Oil 5w40 5 Liter Bottle

The SR-1 Synthetic Oil 5w40 5 liter bottle from TORCO is designed for engine builders, performance mechanics, and serious automotive enthusiasts who require high-quality lubrication for modified and high-output engines. This full synthetic oil formulation is tailored to meet the demands of turbocharged engines, supercharged systems, and heavily modified vehicles, ensuring optimal performance where conventional oils may fail.

The advanced formulation of TORCO's SR-1 combines high-quality base stocks with anti-wear additives and oxidation inhibitors, providing excellent thermal stability and shear resistance. This ensures that the oil maintains its protective film strength even under extreme pressure and heat cycling, making it ideal for high-performance applications. The 5w40 viscosity rating allows for quick cold-start flow while delivering robust protection at operating temperatures.

This 5-liter bottle is perfect for complete oil changes in most four, five, and six-cylinder engines, making it a practical choice for those who prioritize engine longevity and performance. With its full synthetic construction, the SR-1 oil resists viscosity breakdown longer than mineral or semi-synthetic alternatives, extending drain intervals and providing consistent protection against corrosion and wear.
