Best Motorcycle Oil Buying Guide

The following section gets into our buying guide and frequently asked questions. You may still be feeling a little overwhelmed when it comes to choosing a motorcycle oil, but this section is written to provide the further support that you need and answer some of the queries that you may still have. By the end, you will hopefully have a clearer picture of which is the right product for you and your bike.

What to Consider When Buying Best Motorcycle Oil

Before you settle on the motorcycle oil best for your vehicle, you should think more about a few important considerations so you can end up making the right choice. Here are some of the main things to take into account.

  • Type of Motorcycle Oil

There are three main types of motorcycle oil to choose from: mineral oil, semi-synthetic, and full synthetic. Before you choose which one is right, you need to know a bit more about all three. Mineral oil is refined from crude oil. It is highly unlikely that you will need to fill your bike with this variety unless you own an especially old vehicle or vintage bike of some description. Since it is less stable and more likely to break down, it is not great for engines which run at higher heats.

Next, we have the semi-synthetic variety. This is the middle ground variety which mixes synthetic compounds with the crude oil. As well as getting performance benefits, the price will not break the bank.

As for full synthetic motorcycle oils, they are mad made through blending together various compounds. While these are at the most expensive end of the scale, many motorbike owners decide it is worthwhile paying more for the improved performance you can expect to receive.

Choose the type of oil based on your manufacturers’ recommendation, whether you are looking for Harley Davidson oil or another brand.

  • Compatibility

The last thing that you want to do is put the wrong type of oil in your bike. For example, if your engine is designed to take mineral and you put in synthetic, this could lead to your engine leaking oil, which is never going to be a good thing.

  • Viscosity

Viscosity refers to the speed with which the oil flows. If it has a lower viscosity level, it will flow faster and freer. As you would expect, higher viscosity oil has the opposite effect. Be careful of using the wrong viscosity oil as this can cause metal to grind on metal. Again, it all depends on the specific type of bike you own to determine which is suitable.

  • Additives and Cleaning Capabilities

Another point to consider is the additives in the oil. These work to remove debris and acid, both cooling and lubricating your engine. A lot of gunk and debris can accumulate in your engine on a daily basis. You can’t manually clean all this out without taking the engine apart, which as you can imagine, is a task which takes a great deal of time, energy, and know-how. The cleaner your engine, the better it will run for extended periods of time. The wrong type of oil can increase friction in the engine, leading to a shorter engine life.

  • Longevity

Since motorcycle oil is the kind of product which you will want to use multiple times, you may as well invest in a product which has a decent shelf life. The better-quality products tend to offer an increased shelf life, so this is a point which is worth bearing in mind before making a purchase.

  • Reviews

If you have no idea about the type of engine oil for you, the online reviews can be a useful place to look. This gives you a chance to read what more experienced people have said about the oil, and you can potentially find people who have the same bike as you to get more information.

  • Price

While price isn’t the only thing that you should base your decision on, it is bound to be a factor which comes into your mind. An oil with a high price point needs to justify itself by improving the performance of your bike. You should also remember that some of the products above are sold in multi-packs, so you may be able to make additional savings here. Also, there are others which are sold as complete oil change kits, so you will get the other components that you need to change your oil, as well as the fluid itself.

Benefits of Replacing the Oil on Your Bike

You may be wondering about the reasons why replacing the oil in your bike is so important in the first place. The oil keeps all the important elements of the machine working as they should. This ensures that your bike will enjoy a long lifespan, and the performance will remain strong throughout its life. There are those who wait until every single drop of oil has entirely evaporated off by the motorcycle engine, but you are better off getting in there ahead of time and replacing the oil promptly. Otherwise, the engine will have to work much harder, and it is much more prone to overheating as well. Different bikes need different oil, and it is like the lifeblood of the vehicle.

Types of Motorcycle Engine Oil

We have discussed this point in some detail earlier, but we can’t stress enough just how important it is that you choose the right type of oil for your bike. So, let’s go over the three main types of oil once again to help you in your quest to choose the right variety.

Mineral Oils (MO)

First up, you have the mineral oils, which are the most basic product available. This type of oil is only recommended for bikes which have a small engine capacity without much mechanical pressure when running. They are often used by new bike owners as they offer good protection for bikes in the first few kilometers. While they are an affordable option, they don’t tend to last very long, so you will need to keep replacing your oil frequently.

Semi-Synthetic Oils (SS)

We have chosen one or two semi-synthetic oils in the list above, and they have the advantage of providing a balance between mineral and fully synthetic oils. They are a good option for smaller capacity bikes which are not put under too much stress. Better for the daily commute to work than a serious race. Some people suggest making the switch after the bike has been started off using mineral oils. It comes at a higher price point than mineral oils, but not one which reaches the heights of fully synthetic oils.

Fully Synthetic Oils (FS)

Finally, you have the fully synthetic oils, which is the category that most of the above choices fit into. Unlike mineral oils, it is fully artificial and doesn’t use any natural products. If you have a high-performance bike that gets put under a lot of stress on a regular basis, it is a wise choice. Racing bikes and motocross bikes are two examples of vehicles that need this variety of oil. They are made to not degrade quickly, and they have a long-life cycle. An enhanced all-around performance is one of the claimed benefits of this type of oil.

Can I Use Car Oils for Motorcycles?

You should not use car oils for motorcycles as they are not the same thing. If you use the oil that is meant for your car, this can end up leading to damage to your bike engine. One of the main differences is that automotive oil contains friction modifiers to help cars idle smoother. This is specifically designed for emissions regulations; which motorcycle engines do not require. If you put in automotive oil into your motorbike engine, this can result in the clutch slipping and the transmission becoming damaged.

You should also avoid using old motorbike oil which has been on your shelf for a while. As a general rule of thumb, oil with a more complicated formation will have a shorter shelf life.

Motorcycle Oil Changing Tips for Beginners

Regularly changing the oil in your motorcycle is one of the best ways of ensuring that it maintains a long life. And if you do the job yourself, you save the time and effort of having to go into a professional every single time. To show you that it isn’t all that challenging, we have broken the process down below so you can complete it step by step.

To start off with, you are going to need to assemble the right set of supplies. Obviously, you need to get the right bike oil, so choose the one for you from the list above. You will also need a new oil filter, a drain pan and funnel, some box or socket wrenches, and some clean clothes and gloves.

If you are a beginner, you should change the oil cold to avoid burning yourself, but if you have done it before, you may want to take the bike out for a few minutes to encourage it to drain faster when you get to work. Start by choosing a good spot to change the oil. Ideally, you need it to be free of any dust or contaminants. If there are any parts which are blocking your access to the drain plug and filter, you will need to shift these out of the way. Once you have cleared the access, you can place the drain pan underneath the plug to get the old oil. With the wrenches, you can now take off the oil plug, followed by the drain plug.

As the old oil drains out, you can take off the old filer. You may be able to take care of this by hand, or you might need an oil filter wrench depending on the design of your bike. If you are unsure, go back to your owner’s manual to get some more information on the subject. You will then need a clean cloth to wipe clean the oil filter gasket. If your bike has a spin-on filter, it is a good idea to do the job of installing the new filter by hand. It should be tight, but still removable by hand.

The outgoing oil should start to slow down as it exits the vehicle. Check how much oil is required. You can then start pouring it into the bike using a funnel. Don’t go too quickly. You should stop every now and again to check the oil level. Double check that the bike is on level ground so there is nothing distorting the figures. If you go over the ‘full’ marking on the dipstick, you will need to drain out some of the excess oil.

Once you are happy that the oil level is correct, you can put the oil fill plug back in place and clean up any spilt oil. If there any leaks, you can identify them by running the engine. You can then double check the oil levels to make sure that everything still lines up. It may take you a bit of time to start off with, but you will eventually get the hang of changing the oil in your motorcycle and it will become like second nature to you.
