The Benefits of Motorcycle Oil

Lubricate Your Motorcycle Engine

The main function of motorcycle engine oil is to ensure that all of the engine parts are properly lubricated. This is to help minimize friction, reduce wear, and prevent any of the components from overheating.

The engine oil works by lubricating moving parts and covering them with a slick, thick film. Any of the heat or friction that is created in the engine is dissipated through the oil.

For the oil to remain effective, the lubrication system needs to provide a continuous flow throughout the entire engine. That’s why it’s important to continually monitor the motorcycle oil level and stay on top of all oil changes.

Keeps the Engine Cool

Another benefit of motorcycle engine oil is that it dissipates the heat away from the lubricated parts. When the engine is turned off, the oil will return to the oil pan.

When it is in the oil pan, the best motorcycle engine oils will help to lower the temperature of the oil itself. This helps to reduce engine heat overall and prevents any temperatures from going above their flash point

For your motorcycle to keep running efficiently and in the proper temperature range, it’s important that the oil is flowing throughout the engine. If not, this can lead to the engine overheating and other serious engine problems.

Cleans the Engine

There are two basic ingredients in engine oil – additives and base oil. While the base oil helps with lubrication, it’s the additives that provide additional engine protection.

This is done through a cleaning process caused by certain chemicals in the additives. The oil it’s designed to clean up all of the different engine components it comes to contact with.

Specifically, the additives are formulated to remove carbon formations on the engine components, which helps to keep everything running smoothly. With poor quality oils, or a lack of regular changes, these formations can build up and impact engine performance.

Increased Engine Life

A properly lubricated and well-oiled engine will help to maximize the life of the engine. Using good quality engine oil on a regular basis will increase the lifespan of your motorcycle and keep it running smoothly.

Regular oil changes help to minimize sludge buildup while keeping the internal components of the engine clean. They’re also kept well lubricated, so they can continue to operate at an efficient level.

Key Features to Consider

Viscosity

Viscosity is the speed at which the oil flows in your engine. At a lower viscosity, the oil will flow fast and freely.

On the other hand, higher viscosity oil will be much slower. The viscosity can be determined by the SAE rating that you’ll see on most containers.

You probably noticed it, it looks something like “10W-30”. The 10W part represents the viscosity when the engine is cold and the 30 is for when the engine is hot.

Always follow your maintenance manual to ensure you’re using the right viscosity for your engine. Using the wrong viscosity will drastically reduce the efficiency of the oil, which can cause metal on metal grinding in the engine, and lead to further problems or damage.

Additives

Additives are added to motorcycle engine oil to neutralize acidity and remove debris. This helps to clean everything out and ensure your engine continues to run smoothly.

These additives also help to lubricate and cool the engine components. Using the wrong oil can result in a shorter engine lifespan, due to increased friction and overheating.

Oil Grade

The oil grade that your motorcycle uses is very important. This is the rating that reveals which temperature range the oil is as well as the right amount of viscosity for effective lubrication.

As we just mentioned, the “10W-40” rating are the numbers that represent the oil viscosity. The first number is the low temperature rating, with the “W” standing for winter.

The second number is the high temperature rating, revealing the temperature at which motorcycles can continue to perform efficiently. Those of you living in a cold area should buy a motorcycle oil with a lower “W” level.

Compliance Standards

Look on the bottle for any standard marks, ratings, or compliance information. All of the highest quality motorbike oils will have a mark left on the container from the manufacturer.

Keep an eye out for SAE, JASO, or API ratings. These are standards that indicate you’re using a high quality engine oil.

Riding Style

Your riding style also needs to be considered when you’re looking at the different motorcycle oils. Those of you on performance motorcycles, or regularly riding at high speeds and RPMs, will likely be better off with a synthetic motorcycle oil.

Synthetic oils are better equipped at dealing with the higher temperatures of higher performance motorcycles. They’re less likely to break down at extreme temperatures and can continue to properly lubricate the engine.

On the other hand, if you’re a more relaxed and calm riding, consider going with a basic mineral oil. These are less expensive and can be a better choice for lower revving bikes.

Motorcycle Oil Pricing: How Much Does Motorcycle Oil Cost?

Under $20

For less than $20 you’ll be looking at some cheap motorcycle oil options. Most of these are natural blends while you’ll find some synthetic blends at this price point.

If you’re on a budget, synthetic blends are a good choice that provide most of the benefits of fully synthetic oils. While they’re more affordable, you’ll be better off spending a little more for a better quality motorbike oil.

$20 to $30

This is what you can expect to spend for some of the best motorcycle oil options.

These are some of the most popular thanks to the fully synthetic formulas, high efficiency, low viscosity, and better performance available for oils in this price range.

Over $50

You typically won’t find too many motorcycle oils in this price range. The options that are available are high performance lubricants that are better suited for racing bikes.

These oils offer peak performance and low viscosity with efficiency boosting capabilities. They’re not suitable for small capacity motorcycles and should only be used on high performance bikes.

Helpful Tips

  • Before you change your motorcycle oil, double check the drain intervals from the service manual. With natural oils, it should be replaced after 2,000 miles. With fully synthetic oils, it doesn’t need to be replaced until around 5,000 miles.
  • Every time you do an oil change, it’s important to change the oil filter. You never want to use an old, used filter with fresh, clean oil. Using a new filter can provide better performance and increased efficiency from the engine. Check out our post on the best motorcycle oil filters to see our recommendations.
  • After changing the oil, some riders like to add some additional additives. Unless this is recommended in the service manual, you should avoid adding any additional additives to the oil. These additives cost more money and typically don’t offer any benefit to performance, especially if you’re using synthetic oil.
  • Always start your bike and let it warm up before changing your oil. It’s a good idea to let it run for 10 minutes to get the oil warm. This helps it drain better and makes the process easier. Don’t forget to wear safety gear when you’re handling used oil.
  • Along with replacing the filter, it’s a good idea to replace the old washer as well. This can save the threads in your oil pan, since it will take less torque to tighten up the drain plug.

FAQ

Can You Use Car Oil in Your Motorcycle?

While some riders used car oil in their bikes, this is not recommended. Always use the oil that’s recommended in the motorcycle service manual. Using car oil can damage the engine and cause it to perform poorly.

What Oil Should You Use On Your Motorcycle?

To determine the right oil to use, refer to your motorcycle owners manual. This information can also be found in the service manual, if you have purchased one for your bike.

The manufacturer of your motorcycle knows exactly what type of oil your bike requires. That’s why it’s always a good idea to refer to this information, rather than using any random product.

To make things easier, consider using a motorcycle oil drain pan. This catches the oil during the change and makes it easier to properly dispose of.

Should You Use Synthetic or Conventional Oil For Your Motorcycle?

Synthetic oil tends to last longer and is better at lubricating the components in the engine. However, it doesn’t mean you need to use synthetic on every motorcycle.

As previously mentioned, double check with the owner’s manual or service manual to see what’s recommended. This makes it easy to find the most appropriate product to use for your bike.
