Why choose QT Supreme Scooter 10W-40 SL/MB
Duckhams QT Supreme Scooter 10W-40 SL/MB is a semi-synthetic multi-grade engine oil, designed for performance, using modern additive technology and high-quality base oils to meet the requirements of modern four-stroke scooter engines. Duckhams QT Supreme Scooter 10W-40 SL/MB has been carefully formulated to meet the low-friction requirements of modern scooter engines, reducing wear and corrosion and extending engine life, whilst reducing sludge and deposit build-up and maintaining engine cleanliness and performance throughout the oil drain interval. Suitable for use in a wide range of air and liquid-cooled four-stroke scooters fitted with separate automatic, or CVT, transmissions. Also suitable for use in motorcycles not fitted with a wet clutch or a combined engine, clutch and gearbox lubrication system. Not suitable for use in engines fitted with wet clutches, or combined engine, clutch and gearboxes, which require JASO MA, JASO MA1 or JASO MA2 lubricants. Always refer to your owner's handbook when selecting oil for your vehicle.
- Low-friction engine oil for use in scooters with separate automatic transmission systems. Also suitable for motorcycles not fitted with a wet clutch or combined engine, clutch and gearbox, and requiring an oil of this viscosity and specification.
- Formulated using high-quality synthetic base oils with hydro-processed mineral oils to give improved oxidation and thermal stability, even at high operating temperatures, prolonging the life of the oil, ensuring the engine is suitably lubricated, giving sustained engine performance.
- Designed to ensure anti-wear and corrosion protection, irrespective of riding style, throughout the oil drain interval, reducing component wear and extending component and engine life.
- Carefully balanced detergent and dispersant additives reduce sludge and deposit build-up, providing excellent engine cleanliness and maintaining optimum engine performance, power and efficiency from oil change to oil change.
