Castrol Activ 4T 10W-30 Synthetic Technology Engine Oil 1L

Castrol Activ 4T 10W-30 Synthetic Technology Engine Oil 1L is the 10W-30 four-stroke motorcycle engine-oil listing at GearBlack in Bangladesh. Check the model, viscosity and pack size together when comparing products.

Castrol Activ STOP-START 10W-30 is the Synthetic Technology motorcycle pack shown here. Match the full range name as well as the viscosity when comparing Activ bottles from different markets.

Castrol’s Activ range uses Actibond technology to help protect against wear, deposits and corrosion. “Synthetic Technology” on the supplied packaging does not by itself establish whether this version is fully or semi-synthetic.

10W-30 has SAE hot-viscosity class 30. The 10W describes low-temperature behaviour, not engine size. A 10W-40 bottle has a different hot-viscosity class, even if the same brand makes both.

This listing contains 1 Litre. Bottle volume is not the engine’s refill requirement: service refill, filter replacement and dry-engine capacity can differ. Measure the amount required by your exact manual.

Before ordering, match the manual’s API requirement and JASO clutch specification with the bottle. Follow its oil-change schedule, including any severe-use instructions for frequent short trips or heavy traffic.
