Shimano’s Low-Viscosity Mineral Oil is engineered to deliver consistent, high-performance braking across a wide range of riding conditions. Designed specifically for Shimano’s latest generation of hydraulic disc brakes—including M8200, M8220, M9200, and M9220 models—this advanced fluid maintains reliable stopping power while offering smoother modulation and better heat stability. Its lower viscosity allows for more responsive brake lever feel and a more consistent power curve, making it easier to control your speed with precision on descents, in technical terrain, or during high-speed sprints.

Unlike DOT brake fluids, Shimano’s mineral oil is non-corrosive and less aggressive on seals and components, helping to extend the lifespan of your brake system while reducing maintenance needs. The low-viscosity formula flows more easily through modern brake systems, ensuring quicker, cleaner bleeds and more efficient system performance overall. Whether you’re racing cross-country or tackling long, alpine descents, this fluid is formulated to perform consistently without fading or sponginess—even under prolonged braking.

It’s important to note that this specific formula is not backward compatible with older generations of Shimano hydraulic disc brakes. It’s designed exclusively for the newest systems and should be used only with the brake models it supports. Using it in older systems may result in suboptimal performance or system damage.

When precision, consistency, and reliable braking are essential, Shimano’s Low-Viscosity Mineral Oil is the right choice. It’s a small but critical upgrade that supports the full capabilities of Shimano’s most advanced brake systems—ensuring that when it’s time to stop, you can do so with total control and confidence.
