Product Description
MB3000 Scooter 4T 10W-40 is an ester-based fully synthetic 4-stroke motorcycle engine oil meeting API SN and JASO MB for automatic (no-clutch) 4-stroke scooters. It delivers strong high-temperature wear protection, smooth scooter drivetrain operation, oxidation and thermal stability and excellent engine cleanliness for smooth, reliable performance under the high revs and shared engine/clutch/gearbox lubrication of motorcycles.
Key Performance Features
| JASO MB scooter-optimised
JASO MB friction is optimised for automatic (no wet clutch) scooter transmissions. |
High-temperature protection
stable oil film protects high-revving 4T engines under load and heat. |
| Gearbox shear stability
resists viscosity loss from gear shearing in shared engine/gearbox systems. |
Oxidation & thermal stability
resists oil degradation and deposits during hard riding. |
| Engine cleanliness
high-detergency additive system keeps pistons and valvetrain clean. |
Smooth high-rev performance
consistent protection and feel across the rev range. |
Applications & Performance Level
| Applications | Automatic (no-clutch) 4-stroke scooters requiring SAE 10W-40 API SN, JASO MB oil. |
| Specification | API SN — current/applicable API gasoline service category (backward compatible). JASO MB (JASO T903) — Japanese motorcycle oil friction standard for automatic scooters. Shared engine/gearbox — formulated for combined engine and scooter transmission lubrication. High-temperature wear — protects high-revving 4T engines under sustained load. OEM 4T motorcycle — suitable for OEM 4-stroke motorcycle applications specifying SAE 10W-40. |
| OEM Suitability | 4-stroke motorcycles from Honda, Yamaha, Suzuki, Kawasaki and others specifying SAE 10W-40 API SN, JASO MB. Use only where SAE 10W-40 is specified by the manufacturer. |
| Important Notice | Use only where the motorcycle manufacturer specifies SAE 10W-40 and a matching performance level. ”Suitable for” does not mean official approval unless separately certified. |
