CASTROL POWER1 Scooter 4T 5W-40, E4

Castrol POWER1 Scooter 4T 5W-40 is a premium 4-stroke scooter engine oil engineered to optimise performance and protection in modern scooter powertrains, particularly those with continuously variable transmissions (CVTs).


Unlike a conventional 4T bike with an integrated clutch and gearbox, the 4T scooter uses a belt-driven CVT to transmit power from the crankshaft to the rear wheel. Castrol POWER1 Scooter 4T 5W-40 is designed to account for this difference and offers outstanding performance that is optimised for these CVT-driven engines.


The product also contains Scootek Technology, a power-release formula that offers maximum and sustained engine performance without compromising on protection for vital engine components. It offers smooth clutch engagement and powerful acceleration, tested against racetrack durability standards, to provide the perfect balance of high performance and protection.


Castrol POWER1 Scooter 4T 5W-40 is designed for modern scooters where API SL and JASO MB standards are recommended.

Why Choose Castrol?

Castrol POWER1 Scooter 4T 5W-40 is a synthetic lubricant formulated to reduce internal friction and sustain engine efficiency across a wide temperature range in 4T scooter engines. This resilience across a range of temperatures allows the product to address the demands of stop-start urban riding and the sustained high-rev operation typical in scooters.


The 5W-40 multigrade rating means that this product supports reliable cold starts and stable high-temperature performance, and offers effective lubrication from low ambient temperatures through typical operating conditions. It works to keep the engine cool throughout operation, which adds an additional layer of protection for key engine components, and maintains reliable oil consumption and oxidation control.


Designed specifically for 4-stroke scooter engines with belt-driven CVT systems, where standard motorcycle oils may not fully address the thermal and load profiles of scooter applications. The addition of Castrol's Skootek Technology works to minimise internal engine drag and maintain power delivery with quick fluidity. The formulation is engineered to maintain engine integrity under thermal stress, reduce friction losses and support consistent power delivery, particularly useful in urban commuting and varied traffic conditions.


Independent testing by Castrol and detailed product data indicate benefits in acceleration and wear protection relative to baseline oils, and POWER1 Scooter 4T 5W-40 has been shown to accelerate ahead of competitors' market general oils for bikes and scooters. Test data from Castrol shows that POWER1 Scooter 5W-40 accelerates to top speed 4.5 seconds faster than a market general 20W-50 product.


The product also meets relevant industry specifications including API SN and JASO MB and offers smooth acceleration and throttle response under load for compact and high-revving powertrains that require these classifications.
