How to Pick The Best Motorcycle Motor Oils

When you’re in need of new motorcycle oil the abundance of options and brands can be overwhelming. We know you want the best engine oil for your bike and we’re here to help you find the best motorcycle oil brand.

Keeping your motorcycle in peak condition ensures that your bike will run at optimal performance. Consistent maintenance is required to get the best out of your bike but not all tasks require a mechanic. Choosing a bike engine oil is relatively simple with a little guidance and research.

Motor oil is needed to reduce friction between the moving parts of the engine. This keeps the parts in shape, providing good fuel efficiency and keeping a good balance of friction and lubrication.

best motorcycle engine oil

The engine is the most important part of your bike and needs to be cared for with the most attention to detail.

There are many types of oil on the market. Mineral oil, semi-synthetic, and synthetic oils all have their respective purposes and uses. Each of these oils also comes in grades that determine the viscosity and temperature levels that the oil can withstand without losing its position.

If you’re looking to learn more about the best motorcycle engine oil then follow this guide on How to Pick the Best Motorcycle Motor Oils and see the reviews of our top 5 list above!

There is much to consider when in the market for the best motorcycle oil. As simple as it may seem, choosing a suitable motorbike oil is a very important choice and there is much to consider before you buy.

The engine in your bike is composed of multiple moving components that need lubrication to ease the friction between them when they are working to convert the fuel into energy to create a mechanical force.

The metal components of your engine must have oil to reduce friction, without it the friction would cause damage and potentially ruin your engine. So we know what oil does, how about all the different types of oil?

As mentioned above, motorcycle engine oil can be categorized into three main types; mineral, semi-synthetic, and synthetic. Let’s analyze these different types to get a better understanding of the differences between these oils.

Mineral Oil

Using mineral oil for your bike is the original way to keep your bike running at optimum efficiency. As the name implies these oils are made from natural mineral oils and doesn’t include any super complex chemicals found in synthetic formulas.

While these oils are the standard in the industry, some people believe that the less complex molecules are less efficient. Potentially the molecules won’t bond together as well under extreme conditions. This could lead to greater stress on the engine, leading to worn out components.

Mineral oil is favored by cyclists that ride simply to commute. The lower speeds and more casual conditions of a commuter cyclists are fitting for mineral oils. When selling motorcycles companies may use mineral oil to ‘break-in’ the new engines before upgrading to a more technologically advanced oil.

Semi-synthetic Oil

This type of oil blends the best of both worlds, taking natural and chemical ingredients and blending them to a perfect recipe. Blending the oils together makes for a more versatile lubricant that can help keep multiple types of bikes’ engines running smoothly.

Motorcycles that are used for than short commutes and may be running for longer durations through the day prefer the best semi-synthetic motorcycle oil. If you’re running your bike for only a few miles each day a mineral oil may be preferred. Sometime chemical oils with higher viscosity can restrict performance of bikes that are only used casually.

Though these oils work together to make an efficient blend, on average only around thirty percent of synthetic oil is blended into the natural oils.

Synthetic Oils

Motorcycles that are expected to run perfectly under high performance conditions typically opt for a synthetic oil. These oils are completely synthetic and require no blending with mineral oils.

These complex oils are reserved predominantly for bikes that are pushed to their maximum potential on a regular basis. These synthetic motorcycle oils are super lubricating and have a very high temperature resistance.

Be sure you actually need these oils if you are considering using them. People who burn through a full tank of fuel every day on the highway will most certainly need synthetic oil. Someone who rides casually every once in a while will have no use for these oils.

They tend to be the most expensive and will not even help your engine if you’re not riding for long periods of time. Another reason to use these oils is if you live in an area that has intense temperatures, besides these two main reasons you will not need synthetic oil.

We see a distinct difference between these oils. Although synthetic oils are more complex and expensive they are the least versatile than a blended oil or pure mineral oil. But still for high performance bikes synthetic is a must.

Mineral oils cannot handle the high temperatures that high end bikes operate at. The majority of motorcycle owners are considered commuters, this means that mineral oil and semi-synthetic oils are purchased more so than synthetic oil.

Now with a little bit of knowledge about the different types of oils, let’s look at the types of motorcycle engine oil grades.

Bike Engine Oil Grades

I’m sure if you’re reading this you know a little about engine oil. We have all seen the numbers on the front of the bottles; 10×40 motorcycle oil, 5w40 oil and so on. But what exactly do the numbers mean?

There is a common misconception that these numbers are temperatures. While they do refer to temperature, they aren’t actual temperatures per se. Let’s pick apart these numbers to get a better understanding of what they mean and how they affect our choice of motorcycle motor oil.

First off, the W stands for winter. The number that comes before the W isn’t the temperature itself but just a number to symbolize the viscosity, no an actual unit of measuring temperature.

The lower the number before the W then the better this oil is for starting up the engine in the winter. So in turn we see that the lower the number, the lower the viscosity.

The number directly following the W is another relative number symbolizing whether or not the oil is better at holding its position at high temperatures. The larger the number, the better the oil is at staying consistent at high temperatures.

So the oil with the higher numbers after the W will not break down as easily as the lower numbered oils. These viscosity numbers are relative and hold no actual value, it is just an easy way to gauge the viscosity of the oil.

Many manufacturers offer a suggested grade of oil for their bike. Harley Davidson engine oil recommendations may be different than other similar bikes.

It is best to adhere to the recommended grade of oil that the manufacturer suggests, they are the experts and recommend certain grades for a reason.

On average many riders believe that you should stick with the recommended grade for at least six oil changes. Then flush the engine and use an oil that best suits your needs depending on how often, and how far you ride. This gives the engine time to get ‘broken-in’, thus running smoothly and efficiently for many years.

In conclusion we find that motorcycle oil isn’t all that complicated. We need to keep in mind that the effectiveness your engine oil has is also determined by the design and size of your bike. The more and more you use the more wear and tear your engine faces.

Some older bikes may need to be ‘topped off’ with oil when on long journeys. The older you bike gets the more help it’s going to need to keep running efficiently. Changing your oil, cleaning the air filter, and having the injector cleaned at suitable times will ensure your bike performs well for as long as it can.

Question: How do I check my oil levels?

Answer: Be sure to read the manual that comes with your motorcycle. If you’re buying second hand, many manuals are available online from the manufacturers. For the most pat you can check your oil levels using a dipstick.

Wipe the stick clean, be sure to insert it properly, and then check the oil level and color on the stick. Manuals will have specific requirements for certain bikes to know when to change the oil.

Buyer’s Tips for Motor Oil

Your motorcycle’s engine is the most important component in your bike. When it comes to buying the perfect oil you don’t want to be misinformed or purchase the completely wrong oil. Investing some time, and a little money, into high quality oil will benefit you in the long run.

Keeping your engine in pristine condition and making sure it has proper lubrication will ensure years’ worth of smooth and trouble free riding.

Consider how you ride, are you really maxing out your bike’s potential by taking frequent, long trips? Or are you simply commuting a few miles each day? Do you live someplace with extremely high temperatures? These are important factors that play into your choosing of a suitable oil.

Find reviews from people who drive a similar bike as yours, see what they have to say about motor oils they have tried. Keep track of the dates of your previous oil changes, and note what type of oil you used the last time you had an oil change.

The choices you make for your motorcycle today are going to have lasting effects on your riding even years from now. You engine requires meticulous care and attention. Don’t scrimp and just buy whatever oil is on sale, see it as an investment in your bike as a whole.

You can find oil at big box stores, gas stations, and other convenience stores but don’t be too quick to buy the first oil you see.

Shop around to make sure you get a reasonable price on your oil, buying in bulk from Amazon will help you ensure that you’re using the same oil, they carry a wide selection, and they are never out of stock.

Having oil delivered to your door at the perfect intervals doesn’t sound too bad, right?
