10w40 Synthetic Racing Oil Case 3 x 5 Quart

The 10w40 Synthetic Racing Oil Case 3 x 5 Quart from Lucas Oil is designed for automotive enthusiasts and mechanics who require maximum engine protection under extreme conditions. This case includes three 5-quart bottles, making it perfect for multiple oil changes, track days, or fleet maintenance.

Lucas Oil's synthetic 10w40 formulation offers superior viscosity stability across a wide temperature range, ensuring optimal film strength whether the engine is cold-starting or operating at high RPMs. The 10-weight cold flow allows for quick circulation during startup, while the 40-weight hot viscosity provides robust lubrication and wear protection under high cylinder pressures. This synthetic oil resists oxidation and thermal breakdown longer than conventional oils, extending drain intervals and minimizing sludge buildup.

This product is ideal for naturally aspirated and turbocharged gasoline engines, performance trucks, street rod builds, and race-oriented vehicles. Its anti-wear additives protect critical engine components, making it a reliable choice for high-performance applications.
