How to Get the Right Motorcycle Oil
Before you finalize on the best motorcycle oil for your bike, you need to take consideration of few factors for making the right choice. Just because the oil has 5-star review does not necessarily mean to be the perfect match for your motorcycle. You can consider the following points to get the right motorcycle oil:
Type of Oil
Based on the machinery of the engine, the need of oil might be different than others. There are mostly three kinds of engine oil: Conventional, Synthetic, and Semi-synthetic. Conventional oil is made from crude oil and suitable for old or vintage motorcycles.
On the other hand, synthetic oil is a blending of various components. It is comparatively expensive but ideal for modern engines. Semi-synthetic oil is a hybrid of conventional and synthetic oil. It is mostly suitable for high-speed motorcycles.
Oil longevity usually refers to how long a full tank can run without needing to refill again. Quality comes at a reasonable price. You have to keep in mind that the oils which have proven longevity record, can be pricy.
However, your bike is a valuable asset of yours, and you would like to take the best care of it. Rather than buying cheap oils, it is better to go for oils, which have longevity. It will rescue you from the hassle of changing engine oil frequently. In that way, it will be cost-effective also.
The smoothness of your motorcycle largely depends on the internal cleanliness. A significant amount of debris and junk get mixed with the engine oil every day, in amounts you cannot even imagine. Neither it is possible to see the wastes from outside nor can they be cleaned manually.
However, the only way to clean is to change the oil completely, which is time-consuming and also expensive.
At the same time, there are few superior quality oils in the market which have the self-cleaning capacity to keep the engine clean by protecting from the debris produced inside. The cleaner an engine is, the better will be the service.
Another criterion to judge the right oil is the price of the product. The cost of fuel varies on the quantity, workability, and features of the product. Some oils have exceptional longevity. One unit can be used for a long time. Such superior oils are usually expensive, though.
If any oil is costly, the price has to be justified with the service offering. The quantity is another critical consideration. Also, the container must be big enough to cover multiple refills.
Although the price is not the only thing that influences your buying decision, it plays a vital role in decision making. Many oils also come with the offer of multiple containers. Such offers can be cost-effective and used for a more extended period.
Engine oil is like the blood of our body. If your blood group is B+, you cannot intake any other blood types. Engine oil for motorcycles also works in the same way. It depends on the type of engine oil, which is suitable for the motorcycle.
Some engines are ideal for conventional oil only whereas some are the perfect match for synthetic oil. So, you need to follow the manufacturer’s instruction before putting engine oil. If the wrong kind of oil is refilled, the engine will leak that oil at a certain point. That is risky and also causes a waste of money.
Viscosity level is another factor that you should be looking for. The term viscosity usually means the speed of oil flow. If the viscosity level is lower, the oil will run faster and smoother. But a high level will do the opposite and slow down the oil flow.
As a result, the machines do not get enough lubrication leading to the noisy engine. The starting of the engine also becomes rough, and extra effort needs to be given. Therefore, you should look for the oils which have lower viscosity level to enjoy the smoothness of your bike ride.
The review can be an exciting source of your decision making. If you are extremely confused between the oils, you can quickly take a look at the review section. It is the best way to get an honest opinion from the users’ perspective.
You can quickly get an idea of the positive and negative impacts of the oil you are targeting to buy. Also, you can predict which fuel is more suitable for which engines. As people from different backgrounds share their neutral experience, you can get vast information within a short time.
But of course, a review cannot be a significant source of deciding your engine oil. You can use it as a supportive tool in an extremely confusing condition.
Type of Motorcycle Oils
Based on the engine type, the requirement of oil is also different. You should keep in mind that motorcycle engine oil is not generalized. There are 3 different types of oils based on the production component and workability. The details are discussed below for your convenience.
Conventional oil is natural oil extracted from the deeper grounds. It is also known as mineral oil. In general, these oils are made from crude oil. Different additives such as a detergent are added to protect the engine from debris and junk.
If you are aimed at keeping your engine clean, conventional oil should be your first choice. It also benefits in friction modifier. This means it helps to keep the mechanical parts lubricated enough for smooth operation. But the problem is, it breaks down very easily and has less longevity.
Hence, it is not suitable for high capacity engines. If you have a vintage or vert old engine, you can consider conventional oil.
Synthetic oil is the opposite of conventional oil. This means it is not a natural oil but one that is artificially created by human. Crude oil is also used in synthetic oil but not as a base material. It is used as an additive. Viscosity level is an essential consideration for any kind of engine oil.
Likewise, synthetic oil has a low level of viscosity, which means it keeps the engine smoother and runs faster. The overall efficiency of the engine is also developed through synthetic oil.
The only thing that might hold you back is the high price. If you are short on budget, synthetic oil might not be the right fit for you.
If you are confused between natural and artificial oil, semi-synthetic oil can be a wise choice for you. It is a blend of conventional and synthetic oil. Therefore, you can enjoy the goodness of both through semi-synthetic oil.
You can use it on high-speed motorcycles to enjoy the smoothness like synthetic oil. At the same time, you can get the benefit of a cleaner engine for a long time as that provided by conventional oil.
Engine Oil Changing Tips
Regular changing of engine oil is crucial to ensure the longevity of your engine. It is best if you can do it by yourself rather than going to the professionals every time. It will save you time and money.
If you have never done it before, there is nothing to worry about it either. It is not a complicated process. In the following section, you can find the step by step oil changing process.
Oil Changing Location
Firstly, choose a convenient location for oil changing. The convenient location is any place away from dust and contamination. Then you need to drain the oil. If the oil is warm, it is easier to remove it faster and saves time.
But as a first-timer, you better start with cold oil to avoid any accidental oil burn. Then you need to clear the access of the plug by removing extra parts. Put the drain pan underneath the socket and remove the cap with the help of a wrench.
Take off the Oil Filter
As soon as the oil is drained, you need to take off the oil filter. It should be tight but removable by bare hand. If you are unsure, you can use a wrench to take it out.
You can also check the owner’s manual to get a guideline on the plug removing process. Then take a clean cloth and wipe the filter neatly.
Refill With Engine Oil
Then it is time to refill the filter with engine oil. First, check if the bike is on level ground to get the perfect measure. With the help of the funnel, start pouring the engine oil. Do not rush while inserting the oil.
Go slow and keep checking the oil level. If you pour too much exceeding the required level, you must drain out the excess amount of oil.
Right Amount of Oil
Double-check if the oil is poured to the right amount. If the level is correct, put back the plug on the filter. Again, clean the outer area to remove the oil splits while pouring. Then go for a short drive to check if there is any leakage. And you are done!
You are good to go to carry on oil changing by yourself from hereon. You might feel uncomfortable at the beginning, but with practice, you can become a pro.

Q. Why is it necessary to change the oil?
It is necessary to change the oil to maintain the smoothness of your engine. Engine oil lubricates the different part of the engine and helps to keep it fresh.
But many debris and particles are created inside which is not visible and not possible to clean manually. That is why it is important to change the oil to ensure the smoothness of the ride.
Q. Can I use car oil in a motorcycle engine?
No. The purpose of the two oil is entirely different. The function of car oil is to lubricate the multiple moving parts inside.
On the other hand, the purpose of motorcycle oil is to keep the engines lubricated only. At the same time, it also functions in cooling the engine and protecting the gearbox. Using car oil will not fulfill these purposes.
Q. Is there any difference in refilling time-based on the oil?
Yes, the frequency of your engine oil changing will depend on the type of oil you are using. If you are using conventional oil, you have to change the oil after every 2000 miles. But if it is synthetic oil, you can run up to 6000 miles without any change.
Q. What does viscosity mean?
Viscosity means the speed of the oil flow. Lower viscosity level is expected as it ensures faster and smoother flow. Higher viscosity level brings the opposite result, but it depends on the requirement of your engine’s viscosity level.
Q. Is mineral oil and conventional oil the same thing?
Yes, conventional oil is also known as mineral oil. It is the natural type of oil which is extracted from the soil. The main component of it is crude oil.
