A Comparison Between Motul VS Amsoil Motorcycle Oil

No doubt the Motul and Amsoil both are excellent synthetic motor oils. Both companies offer a variety of oil for different types of motorcycles, and each has its own unique benefits. So, which one should you choose? Let’s take a look at a comparison between Motul and Amsoil motorcycle oil and see which is better for you.


When it comes to performance, Motul is the clear winner. It has a higher viscosity index than Amsoil, meaning that it resists thinning out more at high temperatures. This makes it a better choice for engines that are regularly subjected to high stress, such as racing cars or motorcycles. (This is the same concept as to why dedicated motorcycle oils were developed, in lieu of using the same engine oil found in cars)

However, Amsoil is designed to provide superior protection and performance in a variety of different conditions, while Motul motor oils are designed to provide excellent protection and performance in more traditional conditions. Ultimately, the best motor oil for you depends on your individual needs and preferences.


When it comes to comparing Motul VS Amsoil engine oil, quality is one of the most important factors to consider.

Both brands are known for their high-quality products, but there are some important distinctions to note. For example, Motul is a synthetic oil that is designed for high-performance engines, while Amsoil is an American-made brand that is popular among off-road enthusiasts.

Both brands offer exceptional quality, but it’s ultimately up to you to decide which is the best fit for your needs.


It is important to discuss the longevity of each product as this will give you an indication of how often you will need to reapply it to your vehicle. If a product has a longer lifespan, then it is likely to be more sustainable in the long run and will save you money in the long run. For example, full synthetic motor oils cost more up front but offer a longer lifespan.

Motul states that their product will last up to 10,000 miles before you need to reapply it. Amsoil, on the other hand, claims that their product can last up to 25,000 miles before you need to reapply it. This means that Amsoil is almost 3 times as long-lasting as Motul, making it a more sustainable choice in the long run.

It’s worth mentioning that the oil filter should be changed well before 25,000 miles. These numbers are considering the life span of the oil, and how slowly it degrades, but the oil filter will become an issue much sooner. Some people opt to do an oil change and only change the filter, but I prefer to do it all at once inside of a regular interval.


To choose the right motor oil, one of the major things you need to consider is its viscosity. Viscosity is a measure of how thick or thin an oil is, and it’s important because it can affect an engine’s oil pressure and how well the oil flows.

Simply to say, thicker oils are better for high-performance engines because they can provide better protection at high temperatures. They also tend to be more expensive. On the other hand, thinner oils flow better and are therefore better for cold starts. They also tend to be less expensive.

So, what about Motul and Amsoil?

Motul’s oils are on the thicker side, while Amsoil’s oils are on the thinner side. This means that Motul’s oils may provide better protection for high-performance engines, but they may not flow as well in cold weather. On the other hand, Amsoil oils will flow better in cold weather but may not provide as much protection for high-performance engines.


It is another important thing to look out for while picking the suitable one between Motul VS Amsoil Subaru.

Motul is compatible with all types of motorcycle oil, whether it is synthetic, semi-synthetic, or mineral. You can use Motul with complete confidence in any motorcycle.

On the other side, Amsoil is also compatible with all types of motorcycle oil. However, it is not recommended for use in Harley Davidson motorbikes as it may void the warranty.


When it comes to price, there is a big difference between Motul and Amsoil. Motul is a lot cheaper than Amsoil. For example, a 1-gallon bottle of Motul costs around $40, while a 1-gallon bottle of Amsoil costs around $80.

So, if you’re looking for the best bang for your buck, then Motul is the way to go. However, if you’re looking for the best possible product, regardless of price, then Amsoil is the better option.

Motul VS Amsoil- The Winner

So, which is the best to choose between Motul VS Amsoil?

Well, it really depends on what you’re looking for. If you want something that’s high quality and will last a long time, then Amsoil is the way to go. However, if you’re on a budget and you’re looking for something that’s still good quality, then Motul is the better choice.

Ultimately, after comparing everything, we can decide that Motul is a slightly better choice than Amsoil. But you can also choose Amsoil depending on your requirements.
