How to use a 10W40 motorcycle oil
The correct lubrication process that you provide to the engine of your motorcycle is essential to obtain a good operation in the different terrains without forcing the gears. This generated friction could wear them down and deteriorate the life of the machine. That is why apart from using a first-line lubricant such as 10W40 motorcycle oil, you must also learn how to use it to take full advantage of its benefits.
Select tools and workspace
Select a flat place to change the oil, also identifying the tools you will need. So have a newspaper or absorbent paper on hand, so you can place it on the floor with a container to collect the burned oil, a replacement filter, a wrench, and motorcycle oil.
Adapt the motorcycle for an oil change
The oil that you are going to extract from the motorcycle must have an intermediate temperature. In this way, its viscosity level will not be so high, and thus you will avoid complications when draining it. The recommendation is to turn on the machine a couple of minutes before starting the process and immediately turn it off since warming more than desired could accidentally hurt your skin when you are emptying it.
Release the oil contained in the reserve
Take the wrench and place it around the nut. This way, you will be able to exert pressure clockwise to begin to disengage.
Now, before releasing it completely, you will have to place the collecting container under it, so that the oil falls directly into said container and not on the ground. You mustn’t rush and wait for the necessary time until the contents of the reserve are completely emptied so that at the end of this step, you proceed to screw the cap again.
First, you must remove the filter from the engine of your motorcycle with the help of a wrench, trying to be careful not to damage the adjustment nozzle. Then, it is appropriate to clean the oil contained in the edge and lubricate before placing the replacement.
It is necessary that you verify that the model of the new filter piece is compatible with your motorcycle so that when it is screwed, it is not insulated and closed correctly, thus preventing any leakage from compromising its proper functioning.
Pour the new oil
To pour the new oil, it is necessary to remove the cap from the engine tank inlet. In this way, you can introduce the funnel and then pour the lubricant indicated through it, without fear of spilling during the process. Do not forget to replace the lid at the end of filling. It is necessary to verify that it has been adjusted correctly.
It is recommended that you start the motorcycle for approximately two minutes, and with the measuring rod, you check the level reached. If it is lower than necessary, you will have to fill it a little more until you reach the limit.
The most popular brands
We are all aware of the importance that engine oil has in the operation of a motorcycle. This fluid is of great importance for the lubrication of the vehicle, and not just anyone is suitable for a certain model. Here are the most popular brands of 10W40 motorcycle oils, according to users.
The British company is a world leader in the development and development of oils, greases, lubricants, and services for the efficient operation of your motorcycle. The brand began operating in 1909 when the ingenuity and innovative thinking of Charles Wakefield led him to visualize the creation of a company focused on the commercialization of lubricants for cars and airplanes.
In this way of work and research, he managed to find a sufficiently liquid and thick oil formula from castor; This invention would be known as Castrol. From this historic milestone, the brand noted the success of this product, which began to diversify and began the development of individual oils for each engine manufacturer, according to the mechanical and combustion needs of each of the models.
With a direct presence in more than 46 countries, the workforce exceeds 75 thousand people, reaching more than 120 nations worldwide. Its team of engineers and researchers constantly work on perfecting manufacturing processes to provide users with purer, more efficient, and efficient liquids.
Since 1853 Motul has worked to revolutionize engineering, through the development of high-performance products, for the efficient operation of almost any type of vehicle.
Improving all manufacturing processes is part of the main corporate objectives of the automotive company. 1966 was an important year for the brand, which saw the birth of the Century 2100, a semi-synthetic oil that has enjoyed wide commercial and industrial recognition for its optimal performance and the power it brings to the motorcycle.
In 1971, Motul managed to launch its first completely synthetic fluid, a world landmark that made it a benchmark in motorsports. Many awards and recognitions have earned him a place among the leading brands in the distribution and production of oils. It is a difficult market to conquer due to the competition and expansion of other companies that hold these honors.

Frequently asked questions
Q1 Is it better to use a 10W40 or 10W50 motorcycle oil?
This depends solely on two things. The first one is your manufacturer’s recommendation, and the second one is the place where you live. In countries with not very strong winters and hot summers, any 10W30, 10W40 and 10W50 oil will be functional, since fluids are kept at high temperatures.
If your manufacturer has indicated that both types of oils can be used on the motorcycle, then a 10W40 oil may be better, as it is usually cheaper and diluted at reasonable temperatures. If the manufacturer has indicated the use of a specific oil, then choose the recommendation given by the brand to avoid long-term engine problems.
Q2 What are the differences between motorcycle oil 10W40 and 5W40?
The biggest difference between both oils is the change of the first number. However, this has an explanation that constitutes the true character that makes them so different. The first number refers to winter, while the second refers to summer.
Although both oils share the same level of viscosity in the summer, in colder climates, the 5W40 model will be able to flow faster at low temperatures, and this means that the motorcycle’s engine does not have to work too much using a viscous oil, which what would happen with a 10W40 engine with oil.
Q3 Is it better to use 10W30 or 10W40 oil for a motorcycle?
There is not much difference between 10W30 and 10W40 oil, so this may be a personal choice for you. Many brands recommend the use of either when pouring oil on your motorcycle. For that reason, there is no problem with your choice. However, if not, use the indicated oil to avoid inconvenience.
If your motorcycle is used to oil, it is preferable that you do not change it and, if the temperatures are somewhat cold, then choose 10W30 for its texture and density, as this will flow a little faster in this type of weather. However, do not forget that as 10W40 oil is one of the most common, it is still more economical, so it is the choice of many.
Q4 Which is better: 10W40 or 20W50 motorcycle oil?
If you have a modern motorcycle, the best option for you will almost always be the lowest number. 10W40 engine oils are ready to have your motorcycle ready in any kind of weather and are also made for modern motorcycle engine systems.
If your motorcycle has a small engine, the 20W50 oil could damage it instead of helping it. Usually, this type of product is only used in engines that are quite old or have an exacerbated oil consumption when it comes to running. If there is a very strong summer and you need an oil that works with high temperatures, you may need a 20W50. However, it is preferable to consult with the mechanic before.
Therefore, one could say that the best motorcycle oil is 10W40, except that your motorcycle meets the specific cases mentioned above.
Since not all 10W40 motorcycle oils are the same, it is convenient that we verify the protective properties offered by each product, as well as the different standards that it meets, according to what your motorcycle may need.
And the mere fact of complying with the 10W40 standard already involves including in its composition a good amount of compounds designed both to give the engine adequate protection and to meet the corresponding maintenance intervals. An oil that must be synthetic based, since it is the one that offers the best performance during the use process.
As for the standards, as with the rest of the oils on the market, each oil must meet the parameters determined by the manufacturer. Among these are API and JAPO standards, it being necessary that the oil adequately meets those that the manufacturer of your motorcycle has decided. Anyway, for greater safety, you can always choose an oil specially designed for that motorcycle, as indicated by the manufacturer.
Beyond the basic functions, even the most economical 10W40 motorcycle oil includes some additional functions to better take advantage of its properties. Something that can make a difference in any comparison of 10W40 motorcycle oils, so it is worth checking out these properties.
Among them, we have the property of lubricating effectively even in the cold, so that you can enjoy less engine wear and better fuel consumption. Something that also contributes to having a high capacity detergent or cleaner oil, which reduces waste inside the engine and keeps the entire injection and combustion system in a better state.
These advanced functions are also added oils with special properties in order to reduce pollution. A task in which it is worth checking that the oil complies with the EURO standards in terms of contamination, the most common for these oils are the EURO 2 and 3 standards.
As usual in our guides, this section is usually the last important aspect that we include when we talk about motor oils. It greatly influences how much the product costs and also how comfortable or complicated it will be to manage it properly.
To begin, it is convenient to see what needs of change we will have and what is the capacity of the carter of our motorcycle. The greater this capacity and the greater the number of changes you make, the more you will be interested in resorting to larger sizes, such as those of 4 liters. And these formats are the cheapest when it comes to buying, so the cost per liter of oil will always be lower.
However, in case your motorcycle has a little capacity, or you simply have less need to make frequent changes, you can always resort to models with smaller capacity, such as liter bottles. These bottles usually have enough to make a change or a punctual filling on any motorcycle without having to spend more on oil that, once opened, can lose
