Marine Xtreme is an advanced formulation two stroke engine lubricant that surpasses the TC-W3 test procedures established by the National Marine Manufacturers Association (NMMA) for liquid cooled two stroke engines using oil injection and those using gasoline/oil mixtures. The NMMA TC-W3 specification documents, in controlled and standardized engine tests, oil performance in many areas concerning engine operation. These tests measure lubricity, deposit control, wear control, compatibility with other registered oils and the ability to readily mix with gasoline. Marine Xtreme uses an SAE 40 base oil combined with a diluent to insure thorough gasoline/oil mixing. A state-of-the-art ashless additive system prevents engine deposits and provides a high level of protection against scuffing. The advanced additive system used in Marine Xtreme ensures proper lubrication and protection when used at the same gasoline/oil mixing ratio as recommended forthe OEM (Original Equipment Manufacturers) branded oil. Marine Xtreme mixes readily with ethanol blended gasoline and stays mixed indefinitely. It is recommended that engines be tuned for the type of gasoline that is being used. Available in 12 Quart Cases, 1 Gallon Jugs, 6 Gallon Cases and 30 Gallon Drums. Features and Benefits include: Engine Cleanliness: Advanced ashless additive system keeps the engine clean while operating at moderate to high temperatures. Wear Prevention: Careful base stock selection provides engine protection under heavy loads and extended operation at full power by preventing scuffing and wear. Ease of Mixing: Prediluted SAE 40 viscosity oil is easier to mix with gasoline. Gas-to-Oil Ratio: Advanced formulation allows Marine Xtreme to be used at any gasoline/oil ratio recommended by engine manufacturers, including oil injection systems. Typical Application is water cooled and some air cooled two stroke or two cycle gasoline engines. Outboard Motors. Other engines requiring a TC-W3 certified 2-cycle oil. Some two stroke engines (especially certain air cooled models) recommend an ash containing detergent formulation such as TC 502 - check the appropriate application.
