How To Pick The Best Motorcycle Oil

There are so many bike oil reviews out there that you can quickly become baffled. To ensure that you don’t get swayed away by strong sellers and advertising tactics, you should do your research. This way, you will be well informed before making the final buying decision.

That said, the compliant standards, grade, and material of motorcycle oil mark its quality and category type. These features also determine the type of bike you can use the oil inside.

To make the right decision; therefore, it is imperative that you check every technical specification. You should also pick the motor oil that is best suited for your bike and riding needs. Depending on how the oil was produced, the following are the main categories of motorcycle oils:

  • Mineral Oil

Mineral oils are made using petroleum by-products. They were the first types of oils in the industry before synthetic lubricants started being sold. Today, this kind of oil still has its benefits – such as the fact that they are the best options for vintage and old bikes, small capacity engines, and brand new bikes before easing the new engine into synthetic lubricants.

That said, even the best motorcycle oils in this category tend to burn faster and have to get changed on a regular basis. However, they do provide better protection and are pretty affordable.

  • Semi-Synthetic Oil

The evolution of the bike engine created a need for high-performance motorcycle oils. Today, synthetic oils last longer, attract tons of active motorcycle oil reviews and are effective even for high-performance engines.

If you have a medium weight ride in the 125 to 180 cc range, then you might want to reach out for synthetic motor oils. These oils also work well for final engine run in stages.

Semi-synthetics are also effective because they provide the ideal chemical balance as well as the protection coming from mineral oils combined with the performance that synthetic oil provides.

  • Synthetic Oil

Most synthetic motorcycle oils are factory-made and based on polymers. Entirely artificial, these oils are not natural in any way. Therefore, they don’t tend to disintegrate – which gives them a longer shelf life.

That said, these types of oils are the best for use in stressful conditions and when you need your bike to be at its ultimate performance. After your bike’s odometer starts reading in the thousands of kilometers, it is highly likely that your mechanic will recommend that you switch to full synthetic motorcycle oils.

After the engine settles down, it will start performing better, and you’ll enjoy improved run-in time. At this point, you will be best advised to start on synthetic motorcycle oil to boost your bike’s performance further.

Another thing to note about synthetic oils is that they will ensure that your engine, clutch, and gear are well lubricated and continue working smoothly and without vibrations.

Factors To Consider While Buying The Motorcycle Oil

Apart from the make of the oil, there are many other features you need to think about when you are out shopping for the best motorcycle oil. Consider the following:
  • Grade

Although you might not be an expert at motorcycle oils, you need to understand such technical specifications as the grading system of engine oils. With this knowledge, you will be better placed to decide on the best oil for your bike – especially if you’ve read many reviews of different oils.

For instance, alongside the motorcycle oil, you’ll see a number and a W – such as 10W40, 20W50, and so on. This number-word combination denotes the oil grading – which you will come to understand better after you’ve gone through enough reviews.

A good example is 20W50. The W, in this case, refers to winter while the 20 refers to the low-temperature count and the 50 stands for the suitability of the oil in high temperatures.

To this end, if you live in a cold climate, then the number right before the W should be as small as humanly possible. Only by using such oils will you be able to ensure that the oil retains its viscosity even at low temperatures.

  • Compliant Standards

Before you buy any oil because you think it is the best motorcycle oil, you need to read the standards that have been recommended by the bike’s manufacturer. To this end, most bike manuals recommend JASO, SAE, and API certifications as the actual marks of quality where bike oils are concerned.

  • Motorcycle

The oil you end up buying should depend entirely on the motorcycle type you have, as well as the conditions you will be riding in. As far as possible, your bike should be the primary determinant of the category grading you pick.

For instance, if you have an American cruiser or a sports bike, then the 20W50 grading might prove to be the best. However, if you ride an imported cruiser, then you might want to reach out for a 10W40.

On the other hand, if you ride a classic, your best bet would be to stick with mineral oils. A good example would be an old Harley, which would require reliable weight lubrication. With such a bike, 50W would work well.

  • Viscosity

Viscosity refers to the thickness of your motorcycle oil. After reading the manual from your bike’s manufacturer, you will be better placed to understand the different recommendations for different times of the year.

Over and above everything else, you should never reach out for the cheapest motorcycle oil. You really cannot afford to comprise on quality where the health, lubrication, and wellbeing of your bike is concerned.


Is fully synthetic oil better for motorcycles?

Of course, yes, the fully synthetic oil tends to be more versatile and easier to use than others. It tends to be more efficient and long service life. Plus, it is perfect for people who don’t change the oil regularly. Besides, you can use this synthetic oil for winter and withstand higher temperatures, unlike other oils. It is also better for those engines that use different oils. It also enhances cleanliness and reduces oil consumption. Lastly, synthetic oil minimizes frictions and boosts the vehicle’s engine.

What is the best 10W40 Motorcycle Oil?

Castrol Power 1 Synthetic Engine Oil is formulated to ensure fast flow and prolonged service life, reducing engine friction even in harsh conditions. Also, you can use the engine oil in 3 vital components, including the gearbox, clutch, and engine.

At higher temperatures, the synthetic engine oil provides air-cooled performance as well as maximizing engine acceleration. If you love racing or riding, then Castrol Power 1 10W-40 Synthetic 4T Motorcycle Oil will produce extra acceleration at the touch of the throttle. Besides, the engine oil exceeds the API, JASO MA2, and SL requirements.

Can I use 20W50 oil on my motorcycle?

Yes, you can consider 20W-50 oil if you use it in an area with higher temperatures. The formula tends to keep the engine cool, reduces internal friction, and ensures quiet operation. This type of oil will suit you best if you are in higher temperatures or ride for long. Its thermal properties have a high viscosity rating, hence keeping the engine cool to maintain performance.

Is thicker oil better for older engines?

Yes. You can opt for thicker oil in your older engine because it improves oil pressure. The higher the viscosity, the more you will protect worn bearings, clutch, and other components. Another important reason is that when the oil is added to the engine, it will not leak or throw excess smoke out. For hot weather, thicker oil works best.

Can thick oil damage the engine?

Yes, it can since oil plays an essential role in lubricating the engine and its components. If you use thick oil, your engine will be damaged due to internal engine friction.  To avoid damaging the engine, make sure the oil is not too thick or thin. In case you realize the oil is viscous, it is advisable to remove it and fill it with the ideal oil to ensure the engine’s safety.

Final Verdict

Motorcycle oil plays a significant role in ensuring your bike’s engine is well lubricated, clean, and runs smoothly. However, before purchasing any motorcycle oil, ensure you carefully check the service manual to see the drain intervals. You should replace your engine oil after every 2000 miles if you use natural oil and 5000 miles if you are using fully synthetic oil.

Besides that, ensure you change the oil filter when you are replacing the oil for your engine’s improved performance and efficiency. Don’t use additives for long, and if the oil you are using is blended with additives and at the same time you are using additives, then those additives don’t add value to your engine.

As you go about looking for the best motorcycle oils, therefore, you might want to consider giving any of the above a try. As long as the oil you choose meets the user instructions from your bike’s manufacturer, is affordable, and has sterling reviews online and from mechanics, then you should pick it.

  1. I appreciate the extensive over view of the mentioned oils, I would like to see a actual oil comparison of said oils to truly see which provide protection in particular conditions and to what degree instead of self professed claims. Most modern motorcycle engines are high performance by design, even the big twins which seem to lumber down the road puts a great deal of stress on it’s oil. The comparison testing is far and few in between when it is done. Most oil manufactures do not share the results of their findings, however most oils do state the application it was intended for. I personally think most buyers purchase more costly oils out of fear instead of facts.
