Formulated and tested to exceed the NMMA TC- W3 standard requirements for pre-mix, direct oil injection, and newer generation direct injection two cycle engines. Ultimate in protection and performance in all water cooled, two cycle outboard engines. Is recommended for use in outboard engines manufactured by: Bombardier (formerly O.M.C.), Johnson and Evinrude, Mercury Marine, Yamaha, Suzuki, Nissan. Low aquatic toxicity. Reduce spark plug fouling and preignition. Minimized piston deposits. Improved lubricity/scuffing protection, even at higher temperatures. Superior rust protection. Designed to perform with unleaded fuels at fuel to oil ratios up to 100:1. Reduce smoke emissions. Blends easily and stays mixed in cold temperatures, exceeds requirements of an SAE 4 at -40 degrees Celsius for outstanding lubrication protection. Fully compatible with all other TC-W3 and TC-W II lubricants. Dyed blue for pre-mix systems. 5L.
