Valvoline 2-Stroke Outboard Marine Oil is specifically designed to help maintain torque and acceleration of water-cooled, high-revving outboard engines with pre-mix or direct injection systems. It also provides excellent performance in 2-stroke engines of motorcycles, all-terrain vehicles, snowmobiles and personal watercraft. Certified by the National Marine Manufacturers Association (NMMA) to meet or exceed outboard and personal watercraft requirements of top manufacturers, it’s recommended for use in both TC-WII or TC-W3, including premix and oil-injected 2-stroke applications. Pre-diluted for ease of mixing with gasoline, our formula may also be used in direct fuel injection systems. Our premium base stocks are blended with advanced additives and ashless detergent technology to help protect against corrosion and wear, minimizing combustion chamber deposits, ring sticking, cylinder scuffing, piston burning, port blocking and spark plug fouling. So you can spend more time enjoying the water and less time worrying about what’s going on inside your engine.
