Can motor oil be used for motorcycles?

Lubricants are an essential product for vehicles, including cars and motorcycles. Currently, many individuals have a habit of using automotive oil for motorcycles, believing that this type of oil is superior. Let’s join Huynh Chau in finding the answer to the question: "Can automotive oil be used for motorcycles?"

Can automotive oil be used instead of motorcycle oil, true or false?

1. The difference between automotive oil and motorcycle oil

Before searching for the answer to whether automotive oil can be used for motorcycles, you need to understand these two types of oil and the basic differences between them. We will start with the differences between car engines and motorcycle engines, and why these two types of engines cannot use the same oil.

Firstly, automotive engines and the transmission are interconnected, yet each is a separate component. When using lubricants for cars, we will need two separate types of oil for each component. Engine oil cannot be used in the transmission and vice versa.

In contrast, motorcycle engines and transmissions are interconnected and use the same type of oil for lubrication. Specifically, motorcycle oil simultaneously performs the lubrication for both the engine and the transmission.

Therefore, the composition of motorcycle oil is often supplemented with various additives to support the transmission. The most significant difference between automotive oil and motorcycle oil is that automotive oil lacks the friction and lubrication additives for the gearbox that motorcycle oil contains.

2. The risks of using automotive oil for motorcycles

It is not advisable to use automotive oil for motorcycles for an extended period.

Currently, many people have started using automotive oil for motorcycles and have reported positive feedback. Essentially, this is entirely acceptable, but you should only use it temporarily in situations where an urgent oil change is needed, and the appropriate product cannot be found. There are many unforeseen risks when using the wrong type of oil for your vehicle, so it is crucial to change to motorcycle oil immediately afterward.

The greatest risk is that the transmission system may not be adequately lubricated. In this case, the internal gears will wear out faster due to friction, and continuing to use it will lead to severe issues.

Additionally, the motorcycle engine may be at risk when the transmission begins operating. Automotive oil does not sufficiently lubricate the components, causing them to create friction and break apart into small metal fragments scattered inside.

The transmission and motorcycle engine are interconnected and share the same type of oil. Therefore, when oil passes through the engine, it carries all the metal fragments, causing significant damage to the entire engine system. The only solution is to either replace the engine or purchase a new motorcycle.
