DRAG OIL DS3 Synthetic Engine Oil - 20W-50 - 1 U.S. quart 198921

Harley-Davidson V-Twin engines demand oil that can handle extreme heat and sustained high RPM loads without breaking down. DRAG Oil DS3 is a full synthetic formulation specifically engineered for air-cooled cruiser and touring applications, delivering multi-weight protection across your engine, transmission, and primary in a single product. This eliminates the guesswork of mixing oils and ensures consistent viscosity stability whether you're idling at a stoplight or pushing hard on the highway.

The 20W-50 viscosity provides fast cold-flow protection during startup while maintaining a robust film strength at operating temperature. Advanced extreme pressure additives protect gear teeth and bearing surfaces under load, while the synthetic base stock resists thermal degradation far longer than conventional mineral oils—translating to extended drain intervals and reduced wear debris in your crankcase.
