DT40 5w40 Synthetic Oil Case 12 x 1 Quart

The DT40 5W40 Synthetic Oil Case delivers professional-grade engine protection in a convenient 12-pack of 1-quart bottles, designed for enthusiasts and mechanics who demand reliability across diverse driving conditions. This full synthetic formulation is engineered to maintain viscosity stability in both cold starts and high-temperature operation, making it ideal for street-driven modified vehicles, daily drivers, and track-focused builds where engine stress testing is routine. Whether you're running a turbocharged platform, naturally aspirated performance engine, or stock powerplant, having a case on hand ensures you're never caught without premium lubrication during seasonal oil changes or mid-season top-ups.

As a 5W40 viscosity grade, this synthetic oil flows freely at subzero startup temperatures (5-weight rating) while maintaining a robust 40-weight film strength at operating heat, protecting bearing surfaces and ring zones under sustained load. DRIVEN Racing Oil's formulation includes anti-wear additives and oxidation inhibitors that extend drain intervals and resist thermal breakdown—critical for forced-induction engines or vehicles subjected to aggressive throttle cycling. The full synthetic base stock resists sludge and varnish buildup better than conventional mineral oils, reducing carbon deposits on intake valves and piston crowns, which translates to cleaner combustion and maintained horsepower output over extended service life.

This case format is perfect for shops, serious enthusiasts, and fleet operations requiring consistent inventory and cost efficiency on bulk purchases. Mechanics and tuners appreciate the 12-quart case layout for quick access during scheduled maintenance intervals, allowing stocking flexibility without committing to larger drums. Compatibility spans most modern gasoline and diesel engines that specify a 5W40 viscosity grade; always verify your owner's manual or performance specification sheet before use. The compact 10.25 x 9.55 x 14.1-inch case dimensions fit standard shop shelving, and the 23.81-pound total weight remains manageable for single-person handling during installation or storage.
