Motorcycle oil & fluids | Castrol UK & Ireland

2-Stroke engine oils

2-stroke motorcycle engines use a combination of engine oil and gasoline to function, so understanding the correct ratio for your vehicle is very important. Castrol's two-stroke engine oil is liquid engineered with additives that not only help to reduce exhaust smoke, but also control the build-up of harmful engine deposits.

4-Stroke engine oils

4-Stroke engine oil is used for cruisers, touring bikes, sports bikes, and other larger two-wheelers. Motorcycle engines create higher pressures and more power per cc than car engines, which means that 4-stroke cycle engine oil has to work harder to provide the performance and the engine protection that motorcycle manufacturers demand.
