There are a number of motorcycle engine oil types, and making the right choice matters.
Like it says on the ads: It’s more than just oil. It’s liquid engineering. That’s because while oil is an amazing natural resource, it’s the way we refine, re-engineer and even synthesize oil that makes every Castrol oil an essential addition to your motorcycle.
Customized to meet the needs of your engine – and your riding style – Castrol motorcycle oils fall into three broad categories: mineral, part synthetic and full synthetic. They also feature a wide range of different properties, formulations and viscosities to ensure that you always have the right type and grade of oil for your motorcycle, as recommended by the manufacturer.
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.
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.
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.
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.
