Kendall® Marine 2-Cycle Motor Oil is a high-quality, ashless engine oil specially designed for use in water-cooled and most air-cooled 2-stroke cycle engines. It is TC-W3® certified by the National Marine Manufacturers Association (NMMA), and also meets API TC and JASO FB performance requirements for use in air-cooled 2-stroke cycle engines. It is recommended for use in low- to mid-horsepower (up to 115 HP) engines, and may be used in either direct oil injection or premix engines.

Features & Benefits
- Meets all outboard and personal watercraft manufacturers warranty requirements where a TC-W3 oil is specified
- Ashless dispersant/detergent formulation helps minimize engine deposits and pre-ignition
- Minimizes piston ring sticking and helps reduce exhaust port blocking
- Protects against piston and cylinder scuffing
- Good lubricity
- Reduces spark plug fouling
- Good rust and corrosion protection
- Keeps engine parts clean
- Mixes easily with gasoline at low temperatures
- Dyed for easy visibility when mixed with gasoline
- Suitable for either direct oil injection or premix engines(1)(1)Note: For premix engines, always follow the manufacturer’s recommendations for choosing the proper fuel-to-oil mixing ratio
Applications
- Outboard marine engines
- Personal watercraft
- Motorcycles, scooters, and all-terrain vehicles (ATVs)
- Snowmobiles
- Low-output chain saws
- Lawn-care equipment (mowers, weed trimmers, leaf blowers)
