Stens 2-cycle engine oil is specially formulated to protect small engine components with optimal lubrication to reduce friction. This premium grade engine oil will help prolong engine life by reducing wear and lowering operating temperatures. Like all 2-cycle oils, this formula is meant for equipment in which the fuel and oil are mixed in the same holding tank. Stens 2-cycle engine oil is registered and exceeds JASO-FD standards and meets ISO L-EGD requirements. Deep-cleansing detergents aid in easy starting by keeping engine components free of residue and preventing exhaust port blockage. An antioxidant fuel stabilizer protects the fuel system and extends fuel life. This high-grade oil burns cleanly to minimize smoke output. Formula works for either 50:1 or 40:1 applications.
