Shimano Low VIscosity mineral oil for hydraulic disc brakes

Shimano LV (Low Viscosity) Mineral Oil – High Performance: Shimano LV mineral oil represents a major advancement in hydraulic braking system maintenance. With reduced viscosity compared to classic mineral oil, this fluid is designed to offer a faster response and an ultra-precise lever feel, ideal for racing conditions and high-frequency braking.

Why choose Shimano LV oil? The low viscosity of the fluid allows for more instantaneous pressure transmission. In competition (MTB or Road), this translates to:

• Increased reactivity: The response time between lever action and pad contact is optimized.
• Better feel: Finer modulation control, even during repeated high-speed braking.
• High-performance optimization: Specifically developed for the brand's latest high-end models.

Compatibility and Safety: Shimano LV oil is not backward compatible with older braking systems.

• Verification: Use this oil only if your caliper or lever explicitly bears the mention "SHIMANO LV OIL".
• Do not mix: It is strictly forbidden to mix standard mineral oil (red) with LV oil. Mixing can alter brake function and lead to serious system failure.
• Specific seals: The seals of the new levers and calipers are designed specifically for this fluid. Using inappropriate oil can cause leaks or seal degradation.

Some compatible models:

• XTR Series: BL-M9200, BL-M9220, BR-M9200, BR-M9220
• XT Series: BL-M8200, BR-M8200, BR-M8220, BR-MT805

Expert workshop tips

• Dedicated tool: We recommend using a bleed kit (funnel/syringe) exclusively reserved for LV oil. This avoids any risk of residual contamination with standard mineral oil, which would require a complete and tedious chemical cleaning of your tools.
• Systematic verification: Before each maintenance, check the model number on the si.shimano.com website.
