Product Description Castrol Activ Cruise 15W-50 is a premium engine oil engineered for large-capacity cruiser motorcycles. The unique 2.5L volume is the exact refill amount required for the Royal Enfield UCE (Unit Construction Engine), eliminating the need to buy multiple smaller bottles. The standout feature of this oil is Castrol’s Actibond™ Technology. Standard oils drain to the bottom of the engine when it’s turned off, but Actibond molecules “cling” to critical engine parts like a magnet. This provides a continuous protective layer that significantly reduces wear during the three most critical stages: startup, running, and even when the engine is switched off. It effectively fights high-temperature carbon deposits, ensuring your engine remains clean and maintains peak power over time. Key Features: Perfect 2.5L Refill: Specifically sized for the oil sump capacity of the Royal Enfield 350cc/500cc UCE range. Actibond™ Technology: Provides 3X protection by sticking to engine components, reducing startup wear by up to 50%. Superior Thermal Stability: Resists oil thickening and burn-off even during long rides in high-ambient temperatures. Wet Clutch Compatibility: Meets JASO MA2 standards, ensuring smooth gear shifts and preventing clutch slippage. High Oxidation Resistance: Maintains its lubricating properties longer, allowing for consistent performance between service intervals.
