Description
Castrol POWER1 Scooter 4T 5W-40 is an engine oil from the POWER1 line for four-stroke scooter engines. It is intended for machines with an automatic (CVT) transmission and a dry clutch, where the lubricant never reaches the clutch plates.
The oil is rated JASO MB, which denotes a friction-reducing oil, and API SN. No official motorcycle-maker approvals are listed for it.
Typical figures: 14.2 mm²/s at 100 °C, viscosity index 170, pour point -36 °C, flash point 214 °C.
It is not suitable for motorcycles whose wet clutch runs in the engine oil: they need an oil of a different class, designed for wet-clutch operation.
Application
Four-stroke scooters with an automatic (CVT) transmission and a dry clutch, where the manufacturer specifies a 5W-40 oil to JASO MB.
Worth knowing
A CVT and a dry clutch do not by themselves make the MB class right for every scooter: for some models the maker specifies JASO MA, and this oil does not suit them. So look up the JASO class in the owner’s manual for your particular model rather than inferring it from the type of transmission. The rear-wheel final drive is a separate matter: in many scooters it has its own oil with its own change schedule.
The catalogue also lists POWER1 4T 10W-30 from the same line, and it covers a different case: its MA2 class is intended for a motorcycle’s wet clutch. For a scooter that calls for MB and 5W-40 it matches neither the JASO class nor the SAE grade, and its API category is lower, SL. On the data-sheet figures, Scooter 4T also has the higher viscosity index: 170 against 144. The catalogue lists the MB oils on the JASO MB page, and the article on the JASO MA2 and MB classes shows how to find the right class in the manual and in the JASO box on the can.
