Purpose and Specifications

Castrol Power1 Racing 4T 10W-40 is a fully synthetic 4-stroke motorcycle engine oil engineered for high-performance sports bikes. This premium oil uses Race Derived Technology developed through Castrol's decades of racing experience to maximize engine acceleration and power delivery.

Key Performance Features:

• Flows quickly at cold starts while maintaining strength at high temperatures, reducing internal engine friction
• Delivers exceptional acceleration and throttle response under extreme riding conditions
• Trizone Technology protects your engine, clutch, and gears simultaneously
• Complies with catalyst-equipped engines and meets API SL and JASO MA-2 specifications
• Outperforms heavier 20W-50 oils in cold weather and short-distance riding

Viscosity Grade 10W-40: The 10W rating means it flows easily during cold starts (ideal for winter or morning rides), while the 40 rating keeps it thick enough to protect at operating temperatures around 100°C. This balance makes it superior to thicker 20W-50 oils for bikes ridden in varied climates.

When to Use and Replace

Suitable For: All 4-stroke motorcycles (carbureted or fuel-injected) where API SN or lower and JASO MA or MA2 specifications are recommended. Particularly recommended for BMW GS1200 and modern high-performance sports bikes.

Replacement Schedule: Change oil every 5,000 km or as specified in your motorcycle's owner's manual. The 4-liter container provides approximately one complete oil change for most sport bikes, with room for filter replacement.

Operating Conditions: Designed for extreme riding conditions including track use, aggressive acceleration, and sustained high RPM operation. Maintains protection even during short trips and hot weather riding where thinner oils might break down.

Frequently Asked Questions

Q: Why is 10W-40 better than 20W-50 for my bike?
A: The 10W-40 flows faster when your engine is cold, meaning better lubrication from the first second of startup. This reduces wear during cold starts and is especially important for short trips. The 20W-50 requires excessive warm-up time and is unnecessarily thick for most modern bikes.

Q: Will this oil reduce my fuel consumption?
A: Yes. By reducing internal engine friction, this oil helps your engine work more efficiently, which can improve fuel economy compared to heavier oils. The Race Derived Technology specifically targets friction reduction for better power delivery.

Q: Is this oil suitable for hot climates?
A: Absolutely. The 10W-40 viscosity maintains excellent high-temperature performance and provides superior oil consumption control in hot weather. It stays strong at operating temperatures and prevents excessive oil burn-off on hot days.
