Another most common additive in conventional oil is friction modifiers, this helps to improve lubrication.

These mineral oils are cheaper compared to other motorcycle oils and these are commonly used in old motorcycles. Mineral or conventional oils source is ground which is completely natural and also carries some containments which are harmful but these containments gets clear in the refining process.

Synthetic Oil

Can I Use Car Oils For Motorcycle?

Most newbie riders have this question in their mind. The answer is a big No. You can’t use car oil on a motorcycle, it will not only give you the worst riding experience but also damage your engine.

Car oils are used mainly to lubricate internal moving parts of the engine, where motorcycle oil lubricates the engine, keep the clutch and lubricate cool and also protects gearbox. Let’s discuss in brief.

Gearbox Protection

A car uses different oils, one for engine and another for the gearbox, where motorcycle applies same oil for both gearbox and engine. Because of this, motorcycle oil needs to be unique for keeping both engine and gearbox smooth and clean.

Shear Stability

Shear Stability means, the measure of the amount of viscosity that oil may lose between performance. Motorcycle engine oil offers two functions, first one is to lubricate the gearbox and second one is to lubricate the engine. Motorcycle oil has excellent shear stability compared to car oil and shear stability is very important.

Balanced lubrication

A car engine oils main goal is to decrease friction between internal moving parts which offers efficiency and good fuel economy, but a motorcycle oil requires balanced friction because it lubricates the wet clutch. If the level of friction is low then the clutch won’t be able to get engaged which will cause clutch slippage.

Suitable oil: Most important factor is choosing the right oil for your bike. Every motorcycle oils are not same. You have to choose according to your motorcycle requirement. Using wrong oil will not only waste your money, will also damage your motorcycle engine.

Reviews: If you don’t know the difference between different motorcycle oils then check the reviews of people who are already using those oils, read their online reviews and if possible go for suggestions from people you personally know.

Viscosity: Being assured of the oil’s effectiveness, it’s very important and will be healthier for your motorcycle. Because of viscosity oil’s are able to perform optimally, even when oil is subjected to high temperature.

Efficiency: Every rider wants efficiency. Who doesn’t want their motorcycle to perform better with a little amount of oil? It’s also money saving.

Additives: This one is very common and useful factor to consider. Different motorcycle oil contains different additives. Additives improve motorcycle functions.

For example, the mineral oil contains detergent as an additive, as everyone knows detergent has the ability to remove acids and debris, so it keeps the engine clean and not just that, it also increases the performance of lubrication and cooling.

Price: Price is always an issue. But don’t do what most people always do, we always choose a product which is cheap. Don’t do this, in this case, try to pick a perfect oil for your motorcycle. Cheap oils can damage your engine performance.

If an expensive oil will deliver good support to your bike, then don’t hesitate to spend on that.

Grade: If you pay a close look to oils body you will notice a bold “w” along with company name, it will have a number as well before and after “W”, for example, 20W50 or 10W40.

Do you know why is that for? These are the oil grades and you must need to pay attention to this if you are looking for a suitable oil. Let’s explain this.

(20W50) “W” indicates the winter grade and 20 is the lowest temperature where the oil will suit, on the other hand, 50 is the highest temperature where the oil will suit.

So if you live in very cold close to zero, purchase oil which number before W is very low.

Compliant Standard: Just don’t rely on reviews, check if the oils body has a standard mark given by your motorcycle manufacturer. High-quality oils will have SAE, JASO or API mark on their body, these are the marks of high-quality products.
