0W40 Motor Oil 1qt

REDLINE OIL 0W40 Motor Oil in a 1-quart bottle is engineered for high-performance engines that demand superior protection across extreme temperature ranges. Whether you're running a street car, track build, or heavily modified engine, this synthetic blend delivers the viscosity stability and film strength required when factory oils fall short. The 0W40 rating makes it ideal for both cold-start protection and sustained high-load operation, making it a top choice among performance mechanics and enthusiasts who refuse to compromise on engine longevity.

The 0W rating provides exceptional low-temperature flowability, ensuring rapid oil circulation during winter startups and reducing parasitic drag on your crankshaft—critical for turbocharged, supercharged, or naturally aspirated builds where every horsepower counts. The 40-weight base ensures a robust viscosity film under sustained heat and pressure, protecting valve trains, bearings, and cylinder walls when boost levels rise or track sessions demand continuous high RPM operation. REDLINE's proprietary additive package resists shear, maintains film thickness across thermal cycling, and offers superior anti-wear performance compared to conventional motor oils, making it the preferred choice for engines running modified fuel systems, higher compression ratios, or aggressive ignition timing.

This 1-quart bottle is perfect for top-off applications between full oil changes or as part of a fluid refresh on recently rebuilt or modified powerplants. Mechanics and tuners specify REDLINE 0W40 for turbocharged four-cylinders, LS-platform V8s, rotary engines, and import performance builds where extended drain intervals and synthetic lubrication are non-negotiable. The compact quart size stores easily in your shop, track bag, or vehicle, ensuring you always have the right oil on hand for critical maintenance or emergency reserves during competition season.
