Motorcycle engine oils

Castrol® is the global leader in motorcycle lubricants technology and has taken performance testing to new limits at our state-of-the-art research and development facility in Pangbourne, UK. Whether you ride a modern street racer, v-twin cruiser, vintage café racer or prefer an off-road adventure bike, Castrol has an oil to suit your bike and riding style.

Motorcycle racing engines generate internal pressures far beyond those of standard performance engines. So if you race bikes, it's crucial that you use motorcycle racing oil. These contain high performance anti-wear additives and friction reducers that offer the protection racing engines need, but without reducing power or acceleration.

Of all the different motorcycle oil types, synthetic motorcycle oils deliver the greatest protection and acceleration. They combine low viscosity and high protection to meet all the demands of today's high temperature, high performance motorcycle engines. They also help to deliver optimum speed of throttle response.

Castrol's semi synthetic motorcycle oils deliver a balance between the throttle responsiveness of full synthetic motorcycle oil and the protection and economy of conventional or mineral motorcycle oils. They also provide advanced liquid engineering such as Actibond™ technology to ensure continuous protection.

Motorcycle engine oil types include mineral, part synthetic and full synthetic. Castrol's conventional mineral motorcycle engine oils are a budget-conscious choice, but still provide liquid engineering in the shape of Castrol's Deposit Control Formula and Trizone Technology™ to ensure all the cooling and protection your motorcycle deserves.

Some people think that a 4-stroke car engine works just as hard as a 4-stroke motorcycle engine. The fact is that Motorcycle engines create higher pressures and more power per cc than car engines. This means that 4-stroke cycle engine oil has to work harder to provide the performance and the engine protection that motorcycle manufacturers demand.

2-cycle engine oil, also known as 2-stroke engine oil, is an essential lubricant for every two-stroke engine. Yet not all two-cycle engine oils are created equal. 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.
