Two-Stroke Engine Oil Additive Package
Two-stroke engine oil additive packages are specially formulated for air-cooled and water-cooled two-stroke gasoline engines, providing excellent lubrication, deposit control, and combustion cleanliness in the demanding pre-mix and injection lubrication modes. These packages are formulated to meet JASO FC/FD standards for smoke reduction and ring-sticking prevention. They combine ashless detergents, dispersants, antioxidants, and lubricity additives compatible with fuel-mixed delivery systems.
