Purpose and Specifications

Castrol Power 1 Racing 4T 10W-40 is a fully synthetic motorcycle engine oil engineered for high-performance 4-stroke sports bikes. This premium oil uses race-derived technology developed through Castrol's decades of motorsport experience to deliver maximum acceleration and engine protection.

Key Performance Features:

• Flows quickly at cold starts and maintains strength at high temperatures, reducing internal engine friction
• Trizone Technology protects your engine, clutch, and gearbox simultaneously
• Proven to improve acceleration performance compared to heavier 20W-50 oils
• Meets API SL and JASO MA-2 specifications for modern sports bikes
• Fully synthetic formula provides superior shear stability and prevents viscosity breakdown

Operating Temperature Range: Suitable for both air-cooled and water-cooled engines in extreme riding conditions. The 10W viscosity ensures reliable cold-start flow, while the 40-weight maintains protection at sustained high temperatures typical of aggressive riding.

When to Use / Replace?

Replace this oil every 6,000 to 8,000 kilometers or every 6 months, whichever comes first. For track use or extreme riding conditions, consider shorter intervals. This 1-liter bottle is ideal for single oil changes on most modern sports bikes or as a top-up for existing reserves.

Best For: Riders who demand maximum throttle response and acceleration. Designed specifically for bikers who love high-performance riding on the limit.

Frequently Asked Questions

• Will this oil improve my bike's power? Yes. The low-friction formula reduces internal drag, allowing your engine to deliver more responsive acceleration. Test data shows measurable performance gains over standard heavier oils.
• Can I use this in my older motorcycle? This oil is designed for modern 4-stroke bikes where API SL and JASO MA-2 specifications are recommended. Check your owner's manual to confirm compatibility with your specific model.
• Why is synthetic better than mineral oil? Synthetic oil flows faster in cold weather, stays stronger at high temperatures, and lasts longer between changes. It also provides better protection for your clutch and gearbox under aggressive riding.
