Best Oil for motorcycles


Castrol Power1 Synthetic 4T


Other Grades Available: 10w 40, 10w 50, 20w 50.

Castrol is a trusted and time honored manufacturer of a variety of different kinds of motor oil. Many people look to this as a brand that they can trust and they now offer a number of specialized oil options that are tailored for motorcycles.

Castrol Power1 utilizes what they call Trizone technology. This means that the synthetic blend is formulated so as to provide proper lubrication to the three most important spots on the bike: the clutch, gearbox, and, of course, the engine.

It boasts good performance even in extreme conditions of hot and cold. It is a lot more stable than traditional oils, which can lead to a breakdown of the oil and a change in the viscosity properties.

This is classed  oil and is designed for people who want to push their bikes to the limit, without putting the main moving parts of their bike at risk for damage. People who just use their bikes for weekend use likely do not need this level of performance and thus do not need to spend the extra money.

Like the Power1, it also has the Trizone technology, which helps to ensure adequate coverage for those most important elements of your bike's inner workings.
