Optimise the maintenance of your brakes with Shimano 1 litre RSMDBOILM mineral oil, the ideal format for regular cyclists, workshops or enthusiasts who need to bleed several times. Specially formulated for hydraulic disc brakes Shimano, it guarantees constant, precise and long-lasting braking in all conditions.
Its low viscosity improves lever responsiveness and brake pad engagement speed, while ensuring stable performance even at low temperatures.
Unlike DOT fluids, this mineral oil does not absorb moisture, so it lasts longer and requires less frequent servicing.
The 1L format is particularly economical and allows you to carry out numerous purges, whether for several bikes or intensive use.
How many purges can I do with 1 litre?
You can carry out a large number of purges (often 8 to 15 depending on the method), which makes it the most economical format.
Is it compatible with other brands?
Not recommended. Each manufacturer has its own specific characteristics. Shimano recommends only its oil.
What's the difference with the 100 ml or 500 ml formats?
Same product, only the volume changes. The 1L is more cost-effective for regular use.
How should I store the oil?
Keep it tightly closed, away from light and moisture to preserve its properties.
| Format | Usage | Number of purges | Main advantage |
|---|---|---|---|
| 100 ml | Occasional | 1-2 | Compact and practical |
| 500 ml | Regular | 3-6 | A good compromise |
| 1 L | Intensive / workshop | 8+ | Best quantity/price ratio |
