SR-5 GDL Synthetic Motor Oil 5w40 Case 12x1-Liter

The SR-5 GDL Synthetic Motor Oil 5W40 Case 12x1-Liter from TORCO is a professional-grade synthetic lubricant engineered for modern gasoline and light-duty diesel engines. This full synthetic formulation is designed for operators and fleet managers who demand consistent performance across variable temperatures and demanding operational conditions. The 12-bottle case format makes it ideal for workshops, equipment maintenance programs, and high-use environments where reliable oil supply is critical.

SR-5 GDL's 5W40 viscosity rating delivers excellent cold-flow properties at startup while maintaining robust film strength at elevated operating temperatures. The synthetic base stock resists oxidation and thermal degradation far longer than conventional mineral oils, extending drain intervals and reducing overall maintenance frequency. TORCO's GDL (Gasoline Diesel Light) additive package provides enhanced detergency to keep engine internals clean, superior anti-wear protection for critical bearing surfaces, and corrosion inhibitors that protect against fuel dilution and moisture contamination—particularly important in equipment that sees sporadic use or variable duty cycles.

This case format is best suited for maintenance programs supporting small fleets, agricultural equipment, construction machinery, and industrial generators where bulk purchasing reduces per-unit cost and ensures consistent inventory. Each 1-liter bottle allows controlled dispensing without waste. The SR-5 GDL Synthetic Motor Oil 5W40 meets or exceeds API SL/CF specifications, making it compatible with most legacy and modern light-duty gasoline engines as well as naturally aspirated diesel powerplants. Proper storage in a cool, dry location preserves oil integrity and extends shelf life.
