20W50 API SL / JASO MA2Wintex Top Speed 20W50 is a heavy-duty 4T motorcycle engine oil designed for high-mileage bikes and touring motorcycles that demand thicker oil film protection. The 20W50 viscosity grade provides outstanding shear stability in high-temperature riding conditions, reducing oil consumption and extending engine life for motorcycles with higher clearances.
20W40 API SN / JASO MA2Wintex Moto Power1 is a premium semi-synthetic 4T engine oil that delivers superior engine protection with enhanced cold-start performance. The semi-synthetic formulation offers better oxidation resistance and thermal stability compared to conventional mineral oils, making it ideal for modern fuel-injected motorcycles and performance riding.
15W50 API SL / JASO MA2Wintex Bullet 15W50 is specifically formulated for high-displacement single-cylinder and twin-cylinder motorcycles like Royal Enfield Classic 350, Bullet 500, and similar cruiser-style bikes. The 15W50 grade provides a thick, resilient oil film that protects against thermal breakdown during long-distance touring and stop-and-go city traffic.
15W40 CI-4 / CH-4Wintex Multi-Grade Diesel Engine Oil 15W40 is a heavy-duty diesel engine oil formulated for trucks, buses, tractors, generators, and commercial vehicles. It delivers outstanding soot dispersancy, oxidation resistance, and valve train wear protection in turbocharged and naturally aspirated diesel engines operating under severe conditions.
Key recommendations from our lubrication engineering team
20W40 is recommended for everyday commuting and standard 100cc-180cc motorcycles. 20W50 provides superior high-temperature cushion for air-cooled engines and heavy commuter duty in high-ambient climates.
Specially blended for 350cc+ long-stroke touring engines (e.g. Royal Enfield Bullet/Classic), absorbing severe shear stress and maintaining oil pressure during long rides.
Meets strict modern Japanese and American friction requirements, offering optimal wet clutch grip without sacrificing gear protection.
Answers to common questions about automotive engine oils selection, storage, and compatibility.
Motorcycles generally share a common oil sump for engine, gearbox, and wet clutch. Standard car engine oils contain friction modifiers that can cause clutch slipping. JASO MA2 ensures maximum clutch friction grip and smooth gear shifting.
For daily city commuting, we recommend drain intervals of 2,500 to 3,500 km. For touring and semi-synthetic formulations, intervals can extend up to 5,000 km.
Yes, Wintex 20W40 is fully backward-compatible with API SF, SG, and SJ specifications, providing excellent wear protection for both classic and contemporary engines.
