In 2-Stroke motorcycles the engine oil is lubricant that is continuously injected into the crankcase and burned with each combustion cycle. It must prevent piston scuffing and effectively lubricate bearings, at the same time resisting deposit formation and smoke emission.
In 4-Stroke motorcycles the engine oil must simultaneously meet the high-stress protection requirements of the engine, the friction requirements of the clutch pack and the wear protection requirements of the gearbox.
Always follow the manufacturer’s oil change interval recommendations as described in the owner manual. Due to the smaller sump size and higher engine rpm and operating temperatures, motorcycle engine oil change intervals are generally shorter than that for passenger car engine oils.
Castrol Activ with Actibond Molecules clings to and protects critical engine components even when the engine is switched off, providing continuous protection in all riding conditions.
Continuous protection even when the engine is off.
Castrol ACTIV 2T is a mineral motorcycle engine oil, formulated to reduce the build-up of carbon deposits on critical engine parts that can restrict the flow of gases from the engine, resulting in a decrease in power or deposit-induced pre-ignition.
Castrol Activ 2T is suitable for both air and water-cooled motorcycle engines whether lubricated by a petrol/oil mixture, or oil injected system.
Castrol Activ 2T provides mineral lubrication for most street and off-road two-stroke motorcycles. It is recommended for use in the following two-stroke motorcycles, both air and water-cooled:
Castrol ACTIV 4T 15W-50 is a mineral motorcycle engine oil formulated to provide superior engine wear protection and cleanliness. It also provides excellent wet clutch friction stability even in severe conditions.
Considerable research work was done to ensure the upgraded formulation provided enhanced gear wear protection in motorcycle transmissions.
Castrol ACTIV 4T 15W-50 provides good lubrication for all street and off-road four-stroke motorcycles. It is also well suited to a wide range of four-stroke petrol engines used in generators, lawnmowers, and light power equipment.
