Your bike's engine is the source of power, and it is essential to keep it in tip-top shape. That is why an engine can profit from the best motorcycle oil available to reach its peak performance and have a longer lifespan.
One of the main roles of the oil is to make sure that every engine part is lubricated to prevent friction and wear. The oil works by covering all moving or non-moving parts with a viscous slick film. Most engines have an oil distribution system that provides a continuous supply to all parts of the engine.
Engine oil dissipates the heat from the lubricated parts of the engine. Once the engine is shut off, the oil returns to the oil pan and carries the accumulated heat with it. A quality engine oil should be able to lower its temperature once it is on the oil pan. It shouldn't reach past its flashpoint to prevent the formation of combustible vapors.
The two basic ingredients in a motorcycle oil help in the cleaning process - the oil and additives. The oil lubricates while the additives collect the carbon formations around the cavity. The combination of the two provides additional engine protection and allows it to work efficiently.
Because the motorcycle oil cleans the engine and keeps it lubricated, the mechanical system works effectively. The engine can efficiently burn its fuel and maximize the mechanical output, allowing you to run faster and more smoothly.
Obviously, a well-kept engine should last longer than a poorly-treated engine. Keeping a maintained engine not only makes it efficient, but also prolongs its lifespan. The motor oil minimizes and collects gunk deposits to preserve the internal parts.
Motorcycle oil is considered the lifeline of any two-wheeled vehicle, that is why it is essential to know how to choose the right product. Check out the guide we created, so you'll know what to look for in your next purchase.
Generally, there are three types of engine oils readily available in the market. They vary in composition and features that may benefit your motor's engine. Let's take a closer look.
Mineral oils are mainly composed of crude oil combined with additives, such as detergents, to neutralize acids. Frictional modifiers are also added to ensure that the coverage doesn't run out quickly and ensure better lubrication. Mineral oils offer extensive protection for new engines in their first few miles.
Using this oil type on small-capacity engines is highly advisable since there is less mechanical pressure when running, even on its maximum performance. The definite upside of using mineral oil is its affordability, but you might need to have an oil change in shorter intervals.
This is a man-made oil that contains pure crude as a major additive. It has a lower viscosity that ensures a smoother movement within the engine and reduces internal friction. Unfortunately, pure synthetic oils are costly, but it is a small price to pay for better engine performance and a longer lifespan.
As the label implies, this is a mixture of mineral and synthetic oils. The ratio usually falls around 25% synthetic and 75% mineral, but this ratio varies from brand to brand. Semi-synthetic oils offer a great balance in performance and value for money, that is why many riders prefer using them. Ideal for bikes with 125-180cc engines, semi-synthetic oils are best for medium-sized engines.
In simpler terms, viscosity refers to the thickness or the tendency of a fluid to flow at any rate. A low viscosity oil flows faster and indiscriminately, while a high viscosity oil flows much slower. Knowing the right viscosity should depend on the engine manufacturer's specifications. Check the maker's manual to find out the right viscosity that your unit requires.
Engine oil viscosity is expressed as 10W-30, where "W" stands for winter and the number before it is the oil's viscosity in cold weather. The second number after the hyphen is the viscosity in hot weather or how it will flow in higher temperatures. Using oil with the wrong viscosity can cause metal-on-metal grating inside the engine and could be fatal for the rider.
Knowing the types of additives present in the engine oil should be one of the concerns. As we've mentioned before, additives can come in different forms like detergents, and they can remove debris around the engine and neutralize acidity while keeping it cool and lubricated. Most engine oils, whether mineral or synthetic, have at least 10-30% additives.
Inspect the motorcycle oil container if it has marks of compliance. This ensures that the product has high quality and has passed certain standards that meet specific guidelines. If you're not familiar with these letters and numbers, allow us to give you an idea.
The American Petrol Institute (API) has established, tested, and maintained the ratings of viscosity and content of motorcycle oils worldwide. After the API, you should see the letter "S" which denotes that it should be used on engines that use spark. Its absence means that the oil is meant for engines that don't require a spark, like diesel engines.
After the letter S, you might encounter the letters from A to N. The farther away it is from the letter A, the higher the quality of the oil will be. Nowadays, you can find the letters L, M, or N, which are oils intended for modern motorcycles.
JASO or Japanese Automobile Standards Organization set a grading system for motorcycle oils. This grading system is based on the oil's ability to resist clutch friction, protection against engine wear, and pitting in the gearbox. Below are the ratings that they came up with that are intended for four-stroke and two-stroke engine oils.
The Society of Automotive Engineers (SAE) has designed a viscosity grading system for motor oils. They came up with the viscosity rating that we've already discussed previously on the viscosity part of this article. SAE ratings are expressed in numbers and letters, where motorcycle oils are divided into two base measurements: monograde and multigrade.
Monograde oils are used in specific weather conditions. During the summer months, you will need a more viscous oil because the high temperature makes it more liquid. While in winter, a less viscous oil makes cold starting easier. You will need to replace your engine oil depending on the current weather.
Multigrade oils can be used at a wider range of both high and low temperatures. The range is indicated by two numbers with a hyphen in between. This type of oil doesn't need to be changed with the season and isn't affected by temperature like monograde oils, except if it's time for a regular oil change.
Racers or sport bikers have aggressive riding styles; thus, the engine should have more power and speed to cope with the demands. The engine often incurs wear and tear on its parts, which is why synthetic oil is the best product to use. For daily commuters and casual riders, using mineral oil for their engine is ideal since less effort is applied to it.
