Castrol Activ 20W-40 4T is a good choice for most bikes that recommend 20W-40 grade oil and require JASO MA2 specification.

The mileage or drain interval of Castrol Activ 20W-40 4T depends on your motorcycle manufacturer’s recommendation, riding style and conditions. Typically, many bikes require an oil change every 2,000–3,000 km for mineral-based oils. Follow your service manual and adjust intervals if you ride in extreme heat or heavy traffic frequently.

The term 20W-40 in Castrol Activ 20W-40 4T refers to its viscosity grade. It indicates how thick or thin the oil is at cold start and at operating temperature. Compared to thinner or thicker grades, 20W-40 balances cold-start flow and hot-engine protection, provided it matches your bike manufacturer’s recommended viscosity.

You can use Castrol Activ 20W-40 4T in 4-stroke motorcycles that specify 20W-40 viscosity and JASO MA2 or equivalent in the owner’s manual. It is not suitable for engines requiring fully synthetic low-viscosity oils or cars. Always verify your bike’s recommended grade before changing engine oil.
