Buying guide – What is the best 10W40 motorcycle oil on the market?

 

Although it is something that we sometimes put aside, oil is a key element for the health of any engine, both in terms of durability and protection. So if you want to add the best oil you can find to your motorcycle, you just have to take a look at our guide to buy the best 10W40 motorcycle oil, with which to find the perfect product for your motorcycle.

Protection compliance

Since not all 10W40 motorcycle oils are the same, it is convenient that we verify the protection properties offered by each product, as well as the different standards that it meets, according to what your motorcycle may need.

And it is that the mere fact of complying with the 10W40 standard already means 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.

Regarding the standards, as with other oils on the market, each oil must comply with the parameters determined by the manufacturer. These include the API and JAPO standards, being necessary that the oil adequately comply with those that the manufacturer of your motorcycle has decided. In any case, for greater safety, you can always choose an oil specially designed for that motorcycle as indicated by the manufacturer.

 

Advanced features

Beyond the basic functions, even the most economical 10W40 motorcycle oil includes some additional functions to take better advantage of its properties. Something that can make a difference in any 10W40 motorcycle oil comparison, so those properties are worth taking a look at.

Among them we have the property of lubricating effectively even when cold, so that you can enjoy less engine wear and better fuel consumption. Something that also contributes to having a high capacity detergent or cleaning oil, which reduces waste inside the engine and keeps the entire injection and combustion system in better condition.

These advanced functions are also compounded by oils with special properties to reduce contamination. 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 being the EURO 2 and 3 standards.

 

Presentation of the oil

As is usual in our guides, this section is usually the last important aspect that we include when we talk about motor oils. And the fact is that the presentation of that oil is something that notably influences how much the product costs and also how comfortable or complicated it is going to be to manage it properly.

To begin with, it is convenient to see what change needs we are going to have and what is the sump capacity of our motorcycle. The greater this capacity and the greater the amount of changes you make, the more you will be interested in resorting to larger sizes, such as 4 liters. And is that these formats are the cheapest when buying, so the cost per liter of oil will always be lower.

However, in case your motorcycle has little capacity or you simply have less need for frequent changes, you can always resort to models with less capacity, such as liter bottles. These bottles usually have enough to make a change or a one-off filling in any motorcycle without having to spend more on an oil that, once opened, can lose properties.

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, since this generated friction could wear them and deteriorate the useful life of the machine. That is why apart from using a top-of-the-line lubricant such as 10W40 motorcycle oil, you should also learn how to use the product so that you take advantage of all its benefits.

 

 

 

Select tools and workspace

Select a flat place to change the oil, also identifying the tools you will need. So have newspaper or absorbent paper on hand to lay on the floor with a container to collect the burned oil, a replacement filter, a wrench and the motorcycle oil.

 

Adapts the motorcycle for the oil change

It is important that the oil that you are going to extract from the motorcycle has an intermediate temperature, in this way its viscosity level will not be as 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 if it gets hotter than desired it could accidentally hurt your skin when you are emptying it.

 

Releases the oil contained in the reserve

Take the wrench and place it around the nut. In this way, you can exert clockwise pressure to start loosening.

Now, before releasing it completely, you will have to place the collection container under it, so that the oil falls directly into said container and not on the ground. It is important that you do not rush and wait as long as necessary until the contents of the reserve are completely emptied, so that at the end of this step you can screw the cap back on.

 

 

 

Replace the filter

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. Afterwards, it is necessary to clean the oil contained in the edge and lubricate before placing the refill.

It is necessary that you verify that the model of the new filter piece is compatible with your motorcycle, so that when screwing it in, it is not isolated and closes properly, thus preventing any leakage that could compromise its proper functioning.

 

Pour in the new oil

To pour the new oil, it is necessary to remove the cap from the inlet of the engine tank. In this way, you can insert the funnel and then pour the indicated amount of lubricant through it, without fear of spilling during the process. Do not forget to replace the lid at the end of filling, being necessary to verify that it has been adjusted correctly.

It is recommended that you turn on the motorcycle for approximately two minutes and check the level reached with the dipstick. If it is lower than necessary, you will have to fill it a little more until you reach the limit.

Frequently asked questions

 

Q1. Is it better to use a 10W40 or 10W50 motorcycle oil?

This depends on only two things. The first one is the recommendation of your manufacturer and the second one is the place where you live. In countries with mild winters and hot summers, any 10W30, 10W40 and 10W50 oil will be functional, as they remain fluid 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 is 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 problems with the engine.

 

Q2. What are the differences between 10W40 and 5W40 motorcycle oil?

The biggest difference of both oils is the change of the first number, however, this has an explanation that constitutes the true characteristic 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 will be able to flow more quickly at low temperatures and this means that the motorcycle engine does not have to work too much using a viscous oil what would happen with an engine with 10W40 oil.

 

Q3. Is it better to use 10W30 or 10W40 oil for a motorcycle?

Between 10W30 and 10W40 oil there isn’t really much of a difference, therefore this may be a personal choice for you. Many brands recommend the use of either of the two 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 an oil, it is preferable that you do not change it and, if the temperatures are somewhat cold, then choose the 10W30 for its texture and density, as it will flow a little faster in these types of climates. However, do not forget that as 10W40 oil is one of the most common, it is still cheaper, which is why it is the one chosen by 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 one with the lowest number. 10W40 motor oils are not only prepared to have your motorcycle ready in any type of weather, but they are also made for the engine systems of modern motorcycles.

If your motorcycle has a small engine, 20W50 oil could damage it instead of helping it, because, usually, this type of product is only used in engines that are quite old or that have an exacerbated oil consumption at the time of operation. If there is a very strong summer and you need an oil that works with high temperatures, then you may need a 20W50, however, it is preferable to consult with the mechanic beforehand.

Therefore, it could be said that the best motorcycle oil is 10W40, except that your motorcycle meets the specific cases mentioned above.
