Purpose and Specifications

Valvoline SynPower 4T 10W-40 is a premium full synthetic engine oil designed for 4-stroke motorcycles, including high-performance bikes, cruisers, and off-road models with wet clutches. It delivers ultimate protection for engines, gearboxes, and clutches in one shared system, ensuring smooth shifting, maximum power transfer, and resistance to wear even at high RPMs and extreme temperatures from -30°C cold starts to over 150°C operating heat.

This oil flows easily for quick starts in freezing weather, stays thick under intense track or road stress, and fights sludge, rust, and corrosion to keep your engine clean and efficient. Certified to API SN, JASO MA2, and JASO MA standards, it meets top manufacturer specs for Japanese and European bikes. 1L size perfect for precise top-ups or smaller engines.

When to Use / Replace?

• Replace every 5,000-8,000 km or 6-12 months, whichever comes first, for street use; cut to 3,000-5,000 km for racing or severe conditions to maintain peak protection.
• Shelf life: Up to 5 years unopened in cool, dry storage.
