DI40 5w40 Synthetic Oil Case 12 x 1 Quart

The DI40 5w40 Synthetic Oil Case 12 x 1 Quart by DRIVEN RACING OIL is engineered for high-performance engines, street machines, and modified vehicles that demand premium lubrication under extreme conditions. This full synthetic formulation is built for enthusiasts who push their engines hard—whether you're running a turbocharged platform, naturally aspirated build, or daily-driven performance car that sees weekend track time. The 5w40 viscosity rating provides optimized cold-start flow while maintaining a robust film strength at operating temperature, making it ideal for both street and motorsports applications.

DRIVEN Racing Oil's synthetic base stock chemistry is formulated to resist thermal breakdown, prevent sludge accumulation, and protect critical bearing surfaces even when combustion temperatures spike or oil pressure fluctuates under heavy load. The 5w40 weight delivers faster circulation in cold-start conditions—critical for engine startup wear reduction—while the higher 40-weight film maintains shear stability and anti-wear protection during sustained high-RPM operation and extended intervals. This case format of twelve 1-quart bottles is convenient for home garages, shop environments, and fleet maintenance where multiple vehicles or regular oil changes require bulk supply without committing to drums.

Performance-minded mechanics and engine builders rely on DRIVEN Racing Oil for naturally aspirated V8s, LS-series engines, small-block builds, and turbocharged four-cylinder platforms where conventional oils fall short. The 5w40 profile suits four-cycle engines that operate in moderate to severe duty—including vehicles with modified cam profiles, upgraded fuel systems, and tuned ignition timing that elevate operating temperatures. Verify your engine manufacturer's OEM specification and drain interval before use; DRIVEN synthetic oils are compatible with most domestic and import platforms, though always confirm viscosity grade and API certification requirements for your specific application.
