Buyer’s Guide

What is Motorcycle Oil For?

Gas might be what makes a motorcycle run, but oil is what allows it to perform at peak levels. Oil is as vital to a motorcycle as blood is to a human.

But what does a motorcycle oil do to your engine?

Lubricate Moving Parts

The moving parts of your motorcycle are always in danger of grinding into each other, such as the engine and transmission. This friction can damage them over time. 

The motor oil acts as lubrication that coats the insides of your motorcycle, lessening the friction between moving parts. The result is less wear and tear, hence a longer lifespan for your bike.

Helps Remove Heat

The inside of a motorcycle engine is scorching, mostly from the internal combustion of the engine. However, friction between moving parts creates a lot of heat as well.

Motor oil helps lessen the overall heat caused by friction. It does this by carrying heat and dispersing it throughout the system. This helps prevent overheating, ensuring your engine lasts longer and performs at optimal temperatures.

Prevents Rust and Corrosion

The combustion of the motorcycle engine requires a lot of oxygen to burn. However, this negatively affects the metallic parts of your engine by promoting rust.

The motor oil acts as a protective shield, creating a layer that prevents rust or any corrosion from forming.

Protects Against Unwanted Bits and Pieces

As your motorcycle engine runs, it creates a lot of by-products such as soot and dirt. These aren’t always safe for your motorcycle’s internal parts, however, and can cause internal damage if left alone.

Motor oil helps traps and carry these foreign contaminants away from the critical parts of your engine. It is then collected into the air filter, where they can be safely disposed of later on.

What to Look for In A Motorcycle Oil

Make sure it’s specifically for motorcycles

Most motorcycle owners use a motor oil made explicitly for cars for their bikes. They do this because motorcycle oil is significantly more expensive per quart than a car motor oil.

While it will work initially, using car oil for a motorcycle is very inefficient and will cause damage in the long run. It’s because the insides of a motorcycle and a car are vastly different.

Motorcycles are air-cooled, which can degrade motor oil faster. The parts of a motorcycle engine also move faster, and therefore produce more fiction that needed added lubrication. Lastly, some motorcycle engines produce a lot of shear, which can reduce motor oil viscosity and, thus, performance.

That’s why motorcycle oils have additives to account for these differences. And yes, that’s why they’re also more expensive. However, car motor oils need replacement much more often, which might cost more in the long run.

In short, the additives in motorcycle oil can help improve the performance and lifespan of your motorcycle in the long run.

Type of Oil

Motorcycle oil comes in three flavors: mineral, semi-synthetic, and fully synthetic. What you choose will significantly depend on your usage and budget.

Generally, mineral oils are the most affordable option. However, they also degrade much faster and have, therefore, a terrible lifespan. That’s why they’re rarely used, except in smaller engines or by new bike owners. At most, they upgrade to a better oil type after riding for a couple of kilometers.

Fully synthetic oils are made from an artificial source. They don’t degrade as easily as mineral oils. Hence, they have much better performance, longevity, and temperature resistance overall. Fully synthetic oils are the oil of choice for high-performance motorbikes used in racing or heavy-duty riding. They are also much more expensive.

Semi-synthetic offers a compromise between mineral and fully synthetic. It has a longer lifespan than the former, but it is cheaper than the latter. This type of oil is best for moderate users, such as those that ride the motorcycle for their daily commute.


Additives add other potential benefits to your motorcycle oil beyond lubrication. What you choose will, of course, depend on what your needs are and what type of motorcycle you own.

Most additives are anti-wear, which is a welcome addition to help prolong the life of your motorcycle’s internal components. Some additives help clean your engine, which can be a daunting task if done manually.


A motorcycle oil’s viscosity generally describes how “thick” or “thin” it is. The more viscous the oil, the harder it is to flow, and the more it can cling to surfaces. Thinner viscosity means it might not coat your engine’s parts properly, causing friction.

Your motorcycle will have a specific viscosity level your motor oil needs to have. You’ll usually see this described using two numbers in the format “nWn.” An example is 20W50, which represents the viscosity at 0 degrees F and 212 degrees F, respectively. The higher the number, the more viscous it is.

Shelf Life and Price

I’ve lumped shelf life and price together because they are closely related. You want to look for a motorcycle oil that doesn’t degrade as quickly even with repeated use.

If it has an incredible shelf life but is priced higher, that’s much better than buying a cheaper motorcycle oil that might only last you a few months.

Generally, I don’t mind buying an expensive motorcycle oil if it means getting better lubrication, protection, and shelf life. The money you’ll save from unnecessary repairs is more than enough to justify the price differenc
