With motorcycle sales going up, as has the number of engine oil manufacturers. However, not all of them will give your motorcycle the care it needs. Infact, some can even harm your prized ride. So, it becomes vital to choose the best motorcycle oil. By going through the next few paragraphs, you are sure to become a lot more knowledgeable about what oil to use in your motorcycle.

Different Types Of Engine Oils

1. Mineral Oils

Mineral oils are the most crude of all motorcycle oils. Furthermore, they are the direct by-products of petroleum. However, this doesn’t mean they are not good. Infact, for lower capacity bikes, mineral oils are the best motorcycle oils.

On top of this, mineral oils are the cheapest of the lot. You wouldn’t have to burn a hole in your pocket to buy them. However, they do not last as long as other synthetic varieties. You would have to replace them quite often.

2. Semi-Synthetic Oils

In the middle of the spectrum we have got Semi-Synthetic Oils. As you might have figured out, they are a mixture of Mineral and fully synthetic oils. Therefore, they give the advantage of both types, while reducing their respective deficiencies.

With Semi-Synthetic Oils, you get a mixture that can handle high performance, while protecting the bike from internal damage too. Also, they are more long-lasting than mineral oil, while also being way cheaper than fully synthetic oils.

If you are using a bike with middle spectrum displacement, you should definitely get Semi-Synthetic Oils.

3. Synthetic Oils

These are oils that are made in an artificial environment using artificial ingredients. They are used only by people having the best motorcycles in the world and people who can afford them.

Since they are made of polymers, they can make the motorcycle handle a lot of stress, making them perfect for superbikes and racing motorcycles with a lot of power.

Although you have to pay a premium to buy them, you would not have to worry about shelf-life at all. They are very long lasting and won’t reduce in quality in less time. The lubricating properties of synthetic oils are also way better than any other variant.

Factors To Look For While Buying Synthetic Oils

1. Manufacturer’s Recommendation

This should be the first thing that you look at before choosing an engine oil. The people who made the motorcycle will definitely know a great deal about the bike and hence, you should listen to their advice. You can easily find the specifications of the oil needed in the user manual.

In some cases, the manufacturer themselves will have a brand of oil made for their motorcycles. This might be a safe option if you don’t want to experiment with oils from third parties.

2. Viscosity

How easily an oil flows is what decides it’s viscosity. You might think about how that will affect the performance of a motorcycle. However, you should note that it plays a very important role. The viscosity decides the lubrication level within the engine.

If viscosity is on the higher side, more friction between engine parts will mean more power requirements. If it is too low, there won’t be enough lubrication, leading to a damaged engine. There is something called as Goldilock’s Zone, which gives the perfect viscosity for motorcycle engine oils. All companies use that as a reference.

3. Grade

The grade of the oil can seem to be a bit more complicated than other factors. However, once you understand it, choosing a grade becomes easier.

In basic terms, grade defines the viscosity of the oil at different temperatures. It is usually indicated through a series of numbers like 15W40, 10W40 etc.

If there is “W” in between the numbers, it indicates a multigrade oil. Now you may ask what are multigrade oils? These are oils which have different grades, depending on the temperature outside. It is a common phenomenon that viscosity of oil is more in winters and less in summers. Multigrade oils help you in dealing with this problem.

4. Additives

Engine oil additives are the one’s added to improve the performance of the primary oil being added to the engine. Mainly, they help refine the engine by better lubrication of the stock oil.

Usually, additives are no more than 5% of the total volume of engine oil. Just like any other thing, adding too many additives can be counter-productive to the engine’s performance. These days, all three kinds of motorcycle oils contain additives to give a performance boost.

5. Efficiency

Efficiency is something that results as a combination of all the factors we discussed until now. It varies from engine to engine, and there are a lot of factors that go into deciding how efficient the engine oil is.

Some of these factors are, the age of the engine, the maintenance of the engine, power transmitted by it etc.

However, if all these factors are good and the engine oil doesn’t offer efficiency, it will be counter-productive. The efficiency of the oil you choose should also consider the age and type of motorcycle.

If the bike is old, you should always go with conventional or mineral oil. The same is true for motorcycles with low horsepower. If the power is high, you should go with fully synthetic oils to get the best efficiency.

6. Price

Lastly, you should also consider the price of the oil you are buying. If you have a low-end motorcycle, it doesn’t make sense to invest in a higher priced motorcycle oil. It will give no notable increase in performance.

On the other hand, buying cheap oils for your high-end motorbike can be disastrous. It will damage your engine beyond repair. So, read about the compatibility of the oil you choose and ensure to spend only the required amount.
