XP7 10w40 Semi-Synthetic Oil Case 12 x 1 Quart

The XP7 10w40 Semi-Synthetic Oil Case delivers reliable engine protection for street-driven and modified vehicles that demand consistent performance across variable operating temperatures. Built by DRIVEN RACING OIL, this semi-synthetic formulation strikes the balance between conventional mineral oil affordability and full synthetic durability—ideal for enthusiasts running stock or lightly modified engines that see both highway cruising and spirited driving. This 12-quart case (1-quart bottles) provides convenient inventory for regular maintenance intervals without the bulk of bulk purchases.

The 10w40 viscosity rating ensures rapid cold-start flow during winter startup while maintaining robust film strength under sustained load and heat—critical for engines producing elevated horsepower or torque through turbocharging, supercharging, or naturally aspirated modifications. Semi-synthetic blends combine Group II mineral bases with polyalphaolefin (PAO) synthetics, providing superior oxidation resistance and extended drain intervals compared to conventional oils, while remaining cost-effective for budget-conscious build programs. The formulation resists thermal breakdown and sludge formation, protecting ring lands, bearing surfaces, and cam profiles during extended WOT sessions or sustained high-RPM cruising.

Mechanics and tuners favor this specification for LS-series engines, small-block Chevys, Ford 5.0L platforms, and any naturally aspirated or moderately boosted four-cylinder engine requiring a versatile, reliable lubricant. The 10w40 grade works across climates from temperate to warm regions; cold-climate users (below 0°F average) should consider 0w or 5w variants. Each quart bottle integrates seamlessly into routine oil-change intervals, eliminating the need for specialty container storage while supporting systematic maintenance logs across multiple vehicles or track seasons.
