JASO MB is a high-quality engine oil for high-performance 4T engines, offering fuel efficiency. It contains special additives that enhance lubrication and friction control. These additives ensure compliance with JASO MB quality standards. It is recommended for motorcycles requiring low-friction lubricants. JASO MB is particularly recommended for dry-clutch scooters and automatic transmission motorcycles. Features: Developed to meet stringent requirements to help save fuel and protect the environment by reducing CO2 emissions. Testing in four-stroke motorcycles under severe operating conditions has confirmed excellent wear protection. Its formulation provides a high level of performance, in turn, sufficient friction reduction for oil-coated parts. Should only be used when the SAE 10W-30 viscosity rating is recommended by the motorcycle manufacturer.
