Castrol Activ 4T 10W-30 is a mineral lubricant for 4-stroke engines. Actibond molecules attach to metallic surfaces to prevent oil drain-off during inactivity. It carries API SN and JASO MA-2 ratings for clutch and engine performance. Compared to the 20W-40 predecessor, this version adopts a 10W-30 viscosity and moves from API SL to SN for better deposit control.
Key Features
- Actibond Technology: Mineral molecules cling to engine parts during the off cycle. Prevents metal-to-metal contact during cold starts.
- 3X Protection: Lubrication covers start-up, running, and engine-off stages. Reduces engine wear by 75% during operation.
- API SN Rating: High-temperature deposit protection for modern 4-stroke engines. Controls sludge formation in heavy road dust.
- JASO MA-2 Specification: High friction coefficient for wet clutch systems. Prevents clutch slippage in stop-start traffic.
Frequently Asked Questions
Is Castrol Activ 10W30 good for bikes?
It provides 75% better wear protection for 4-stroke engines. The JASO MA-2 rating ensures smooth clutch engagement.
What is the benefit of Actibond technology?
Molecules physically stick to engine components even when the bike is off. This prevents dry starts where most engine damage occurs.
