No. SRAM and Avid hydraulic disc brakes are designed to run on DOT brake fluid, not mineral oil, and the two fluid types are chemically incompatible with each other's seal materials. Putting mineral oil into a DOT-fluid brake system, or DOT fluid into a mineral-oil system, can cause the internal rubber seals to swell or degrade, leading to spongy braking, leaks and potential brake failure, so always check your specific brake model's manual before topping up or bleeding.

Shimano, Tektro, Magura and most Formula hydraulic disc brakes typically use mineral oil, while SRAM and Avid hydraulic brakes typically require DOT fluid; the brake lever body or your bike's manual will usually confirm the correct fluid type. When in doubt, it is safer to have a bike mechanic confirm the system before bleeding, since using the wrong fluid can damage seals that are not easily replaced at home.

Most riders bleed their mineral-oil brakes when lever feel becomes spongy, after any air enters the system, or roughly once a year for bikes ridden frequently in Indian heat and dust, since moisture and grime ingress over time can affect brake feel. Regular bleeding also helps maintain consistent lever throw and stopping power on daily commutes and long rides.

Keep the bottle tightly sealed, upright, and away from direct sunlight or extreme heat, ideally at normal room temperature, so the fluid retains its properties for future top-ups. Once opened, try to use it within a reasonable period and always shake gently before use if it has been stored for a while.
