MC-4ST 15W-50 is the superior performance premium engine oil with 100% PAO & Ester, synthetic base oils combined with advanced additive technology including Full Zinc + (exceeding 1800+ ppm levels) for maximum engine, gearbox & clutch protection against wear, corrosion, oil oxidation, piston deposits and sludge under all conditions. It exceeds the requirements of API SN/CF and JASO MA.

Application:

• MC-4ST 15W-50 is designed for use in most modern four-stroke road & sports bikes, dirt & enduro bikes, ATVs/Quad bikes, and 4-stroke scooters that require a full synthetic engine oil. It is also equally suitable for use in transmissions with wet clutch systems where engine & gearbox oils are combined. It has optimum clutch slip prevention in these systems being compliant with JASO MA as it is suitable for use where JASO MA1 and JASO MA2 are specified.
• MC-4ST 15W-50 can be used where semi-synthetic or other types of oils are specified by the manufacturer, including where SAE 15W-40 & SAE 20W-40 & SAE 15W-50 grade oils are recommended, such as in Aprilia, BMW, Honda, Kawasaki, KTM, Moto Guzzi, Suzuki, V Moto, Yamaha, and more.
• MC-4ST 15W-50 contains 100% PAO and Ester base oils that provide superior oil film strength, heat resistance, and oil shear protection combined with a shear free formulation that eliminates viscosity loss and maintains oil pressure during extreme engine operating conditions, ensuring the ultimate in protection for your engine.
• MC-4ST 15W-50 is also suitable for use in other four-stroke engines such as stationary engines & generators or other vehicles that require this grade and specification of engine oil. It is suitable for use with most petrol, racing, and other conventional fuels.

Full Zinc + = Zinc level + Boron level combined as a total anti-wear package.

Benefits:

• Premium 100% PAO and ESTER base oils for maximum heat resistance and high performance.
