Castrol Power1 Ultimate 4T 10W-40 Full Synthetic 1L is the 10W-40 four-stroke motorcycle engine-oil listing at GearBlack in Bangladesh. Check the model, viscosity and pack size together when comparing products.
Power1 Ultimate 10W-40 is Castrol’s full-synthetic 4T product. It is a separate range from Activ; engine capacity alone does not decide whether Ultimate is appropriate for your motorcycle.
Castrol’s Power1 Ultimate reference describes a full-synthetic 5-in-1 formulation. It focuses on motorcycle performance and protection; published test distances are not oil-change instructions for your bike.
10W-40 combines the 10W low-temperature class with SAE hot-viscosity class 40. Oils from different ranges can share this grade while differing in base-oil technology and API/JASO performance.
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.
