Metal Guard 4T Extreme Friction Reduction 10W-40 Motorcycle Oil 1L API SL JASO MA MA2

Metal Guard 4T 10W-40 is an advanced, multigrade semi-synthetic oil designed for modern and heavily loaded four-stroke 4T engines.

Thanks to Metal Guard technology, the oil creates a durable protective layer on metal surfaces, reducing friction and helping protect engine components against premature wear. The product has been developed for motorcycles, quads, ATVs and garden equipment powered by four-stroke engines.

The oil can be used in both liquid-cooled and air-cooled engines, including under intensive operating conditions and during prolonged operation at high engine speeds.

Key properties

Metal Guard friction reduction technology

The special formula creates a durable and highly resistant oil film on metal surfaces. This protective layer helps reduce internal engine resistance, supports engine efficiency and protects cooperating components against accelerated wear.

Suitable for wet clutches and gearboxes

The oil has been optimised for use in integrated engine, transmission and wet clutch systems. JASO MA and JASO MA2 classifications confirm its suitability for motorcycles equipped with wet clutches.

The formula supports precise gear changes, helps reduce the risk of clutch slippage and provides protection for motorcycle transmission components.

Engine cleanliness

Detergent, dispersant and anti-oxidation properties help reduce the formation of high-temperature deposits, carbon build-up and sludge.

The oil supports engine cleanliness and helps maintain the correct flow through oil channels and the oil system.

Thermal stability

A flash point of 232°C and properly selected viscosity provide stable lubrication properties at high operating temperatures.

The oil can be used in both liquid-cooled and air-cooled engines, including during intensive riding and prolonged operation at high engine speeds.

Protection during cold starts

A pour point of -35°C allows the oil to maintain suitable fluidity at low temperatures. This supports rapid oil circulation after engine start and efficient lubrication of upper engine components.
