SR-5R Synthetic Oil 5w30 Case/12-1 Liter

TORCO SR-5R Synthetic Oil 5W30 is a full synthetic motor oil formulated for engines requiring premium lubrication under demanding operating conditions. This case contains twelve 1-liter bottles, making it ideal for fleet maintenance, service shops, or operators who depend on consistent oil quality across multiple vehicles or equipment. The 5W30 viscosity rating delivers reliable cold-start protection and sustained film strength at operating temperatures, making it suitable for modern engines in diverse climates and duty cycles.

The synthetic base stock in TORCO SR-5R provides superior oxidation stability compared to conventional mineral oils, extending drain intervals and reducing deposit formation in critical engine passages. The 5W viscosity rating ensures pumpability in cold weather without sacrificing the 30-weight film strength needed at normal operating temperatures. This balance is essential for engines operating in temperature extremes—whether in high-altitude regions with cold starts or in sustained high-load scenarios where oil breakdown accelerates. Full synthetic formulations also resist sludge accumulation, preserving engine cleanliness over extended service periods.

This bulk case format serves shop professionals, fleet operators, and serious enthusiasts who rotate vehicles regularly or maintain multiple pieces of equipment. Buying in twelve 1-liter units reduces per-unit cost while ensuring consistent product quality across all oil changes. The individual liter bottles provide flexible deployment—use one bottle per oil change without committing to gallon jugs, and store the remainder in a controlled environment to maintain product integrity. Verify that SR-5R meets your specific engine manufacturer's oil specification before use, as synthetic oils are formulated to satisfy particular performance standards and viscosity grades.
