4100 Power 15w50 Oil Case 12 x 1 Liter

The 4100 Power 15w50 Oil Case 12 x 1 Liter from MOTUL USA is purpose-built for high-performance engines and modified vehicles that demand robust protection under extreme operating conditions. This case format delivers twelve individual one-liter bottles, making it ideal for shops, racing teams, and enthusiasts who maintain multiple vehicles or require frequent oil changes on heavily modified powerplants. Whether you're running a naturally aspirated build or a turbocharged platform, this synthetic-based formulation is engineered to handle sustained high-RPM operation, aggressive engine tuning, and severe thermal stress.

MOTUL's 15w50 viscosity grade delivers a thin cold-start flow profile (15w) that ensures rapid oil circulation during startup, while the 50-weight hot viscosity maintains a protective film layer across bearing surfaces, piston rings, and valve train components at elevated temperatures. This dual-viscosity design is critical for forced-induction applications and engine builds running higher combustion temperatures—the 50-weight thickness resists shear breakdown and maintains pressure stability even under peak boost or sustained load. The synthetic base stock provides superior oxidation resistance and thermal stability compared to conventional mineral oils, extending drain intervals and protecting against deposit formation in turbocharged or supercharged engines where heat stress accelerates oil degradation.

Mechanics and performance builders favor this formulation for import and domestic sports cars, diesel pickups with engine modifications, and any platform where oil temperature regularly exceeds 250°F under load. The 12-pack case format accommodates service intervals on vehicles with 5-quart to 8-quart capacities—allowing multiple complete oil changes without reordering. Verify your engine's OEM or tuner-recommended viscosity grade and API certification requirements before use; 15w50 is commonly specified for older muscle cars, modified small-block engines, and turbocharged applications where heavier protection is non-negotiable.
