SHIMANO mineral oil MTB SM-LVOIL 500 ml low viscosity for SHIMANO disc brakes

With the development of the new XTR Di2 kit (especially the M9200/M9220 brakes), SHIMANO decided to go the route of higher sensitivity and faster response. The new low-viscosity oil has a significantly lower density than the traditional pink SHIMANO mineral oil, which means faster flow in the brake system, less internal friction and more precise dosing of braking power.

In sharp downhill, high temperatures, and even in freezing conditions, the brakes behave more consistently as a result - the lever returns faster, the pressure is more stable, and the overall braking feel is sharper and more predictable.

Technical specifications and performance

Low viscosity = higher fluid flow rate
Increased thermal stability in extreme conditions
Permanent mineral base (not a DOT fluid)
Suitable for XC, trail, enduro and technical riding

Please note: new fluid is not compatible with old fluid

It is important to note that the new low viscosity oil is not miscible with the original SHIMANO pink mineral oil. This means that a complete bleeding of the brake system and a thorough flushing of all components is required when switching. In addition, SHIMANO does not recommend using the new oil in non-supported brakes as the different viscosity may affect seals or operation of older models.

How often to bleed brakes

The frequency of bleeding depends on riding style, conditions and brake type, but in general the following recommendations apply:

Recreational riders: once a year, or if you notice a deterioration in brake performance.
Regular and sport riders (MTB, enduro): once a year is the minimum, ideally more often if you ride in mud, rain or mountains.
Racing and intensive use: several times a year - as needed, sometimes every few months.


SHIMANO shows once again that it is one of the world's top manufacturers of MTB brakes. The new low viscosity oil pushes the limits of braking performance one step further - provided, of course, that you follow the correct service procedure and compatibility. If you own a new generation of XTR brakes and want to get the most out of your bike, this upgrade definitely makes sense.
