Motul 600 vs 660

Braking is necessary in any vehicle because its function is to stop the movement and there are lots of parts working together to cause your car or motorcycle to stop from its previous running state. Brake fluid like Motul 600 vs 660 are important to keep these components moving and properly activating the system. These fluids are designed for your racing vehicles but, before you shop for one, go see if there is any difference between the two so we can pick the best option.

Automotive Fluid

Our cars and motorcycles are an important part of our daily life because they are the one that transport people and belongings from one place to another, conveniently. Of course there is public transportation but sometimes they are not as convenient or too far from your stops which require us to spend more effort. As important as they sound, we also have to take care of them properly in an attempt to make them runs properly when we need a drive or ride.

We are sure most people check their vehicle regularly to make sure there is no occurring issue that needs to be handled quickly but the most common routine we do besides changing the tire is changing the oil itself. If you are here then we are sure you love driving a car or riding a bike and similarly in both of them oil is playing an important role to provide lubrication for all of the moving parts, cooling the surface since moving parts will generate heat, and keeping your engine clean.

All of them are necessary to keep our engine runs smoothly and starting with lubrication, the oils will aid this moving parts by coating them and ensuring these metals do not wear on each other. Second, as they are moving against each other, there will be heat generated as well and the oil will cools them or dissipate to the outside of an air cooled engine or to come in contact with the cooling system. Additionally, the oil will hold carbon together with other particles and prevent sludge or debris from piling up.

Brake Fluid

Besides engine lubricants, we also have to pay attention to other fluids for the vehicle and one of the most common fluids we have to change routinely is brake fluid. This fluid is very important because it will affect your braking system and keeping it reliable as well as consistent to ensure the vehicle will stop when you activate them. In general brake fluid last longer than motor oil because we mostly replace them for only once a year or once every two year.

Brake fluid is made from Glycol most of the time and it is hygroscopic which means it will absorb moisture when exposed despite being just in the air. Brake system is a sealed system but moisture will still be able to make their way through seals and hoses. When it happens in a prolonged time, the fluid will continue to absorb moisture and water down them as well as degrade the performance or capabilities. Water will also lower the boiling point and makes the fluid work even less effective when the bike or car warms up.

About Motul 600 and 660

As with many other things, certain products are made for certain purposes but there are also those made to be versatile enough for most users to utilize and brake fluid is in the middle of this. There are surely brake fluid designed for most applications but there are also those made to give a higher performance depending on your car/bike but, for fluid brake and motor oil in general, those racing types are the one that need these premium products.

Talking about brake fluid, one of the best bets is Motul because this company has been around for more than a hundred years and continue being one of the best when it comes to quality and innovation which makes lots of riders and drivers rely on their products. They carry quite a lot of options in the catalogue for your application from engine lubricants made for racing bikes like Motul 7100 Vs 300V to brake fuel for the same type of activities.

If you are the type to drive or ride aggressively, the most suitable option will be Motul 600 and 660 because these two are designed exactly to allow driver or rider push their limit and of course both are highly capable in terms of keeping your brakes working properly. Similar to how summer tires are expensive, racing brake fluids are not cheap as well but they are the most ideal choice for the application yet, if you don’t have such hobbies, there are a lot more affordable fluid to pick instead.

Motul 600 and 660 are close brothers and the latter is simply a step up of the little brother so if you ever use the former, the latter will be familiar as well but most people who have been used both of them do think that 660 is a superior fluid designed for more extreme applications. However, in terms of popularity 600 is still winning probably because it already works great yet offered in a fairly affordable price.

Motul 600 and 660 Purpose

These brake fluids are very similar to each other on various different types but for those who wonder what they can be used for, Motul 600 and 660 are both car and motorbike brake fuel made for all-types of hydraulic actuated brake and clutch system that require the non-silicon synthetic fluid. They are made to be able to resist a very high temperature of racing actuated brake be it steel or carbon clutch and carbon or ceramic brakes respectively, as well as minimize air entrance.

Motul 600 and 660 Rating

Moving to the brake fluid types, these two are similarly DOT 4 as you can see on the bottle and it is currently the most common grade being used today but not the only one. If you are not familiar with fluid grading yet, there are DOT 3, 4, 5 and 5.1 available in the market. The DOT 3, 4, and 5.1 are very much similar to each other because they are made based on glycol and can be mixed together if needed. 

DOT 5 on the other hand is based on silicone and can’t be mixed with the other. Many people seem to confuse the 5.1 to be similar to 5 but they are different and we also wonder why it is not DOT 6 or 4.5 instead. The difference between glycol and silicon based is that the former will attract and absorb water from the air while silicon is resistant to water. However, due to the repeated cycles and imperfect sealing, both are prone to ingest water as being used in a prolonged time.

The different is DOT 5 doesn’t attract water on its own which makes it last a bit longer and as most may already know, glycol may cause paint to bubble while the same problem should not happen with silicon based fluid.

Motul 600 and 660 Boiling Temperature

While Motul 600 and 660 are made or based on the same substance, they are not exactly the same because as it has been mentioned above, the latter is made to be a higher fluid and for more extreme applications. A racing brake fluid have to be able to take the heat generated from lots of braking and the 600 fluid is rated very high before reaching boiling point at 312 degree Celsius and even more superior than DOT 5.1 non silicone base. 

It is even higher than the silicon base DOT 5 which commonly boils at 260 degree Celsius and DOT 4 at 230 degree Celsius. On the other hand, 660 brake fluid is slightly better because it is rated to boil at 325 degree Celsius or 617 degree Fahrenheit. Overall both of them are promoting effective brake including in extreme conditiosn as well as reduce air entrance for brake cooling if you are driving. When it is raining, the wet boiling point are 204 and 205 degree Celsius respectively.

Motul 600 and 660 Performance

Last but not least is performance and both of Motul 600 and 660 are equally amazing that they can easily surpassed the higher rated fluid. Comparing the two there is almost no difference for regular aggressive driving or riding so we are not sure how far the latter can actually improve braking system since they are providing the same performance in practice so unless your application is excessive, 660 is still overkill.

Motul 600 vs 660

- For hydraulic actuated brake and clutch systems
- Non-silicone synthetic fluid
- Extreme thermal resistance and stability
- Very high boiling point (312 degree centigrade / 594 degree Fahrenheit)
- For hydraulic actuated brake and clutch systems
- Non silicone synthetic fluid
- Extreme thermal resistance and stability
- Very high boiling point (325 degree centigrade / 617 degree Fahrenheit)

These brake fluids are a great choice for anyone who is driving or riding more extremely for they are made for this application. In comparison the latter is superior because it has slightly higher dry and wet boiling point to make sure your braking is performing properly despite being abused. They are similarly DOT 4 and based on glycol but the rating is easily surpassing DOT 5 silicone or 5.1 non silicone while performance wise they are equally reliable.

Conclusion 

All in all the decision is all yours because not all of us will have the same opinion but between the two, we do recommend getting Motul 600 because it is an already amazing brake fluid but also more affordable than 660.
