Review: Easy to use, works just as good as the OEM mineral oil. - I had to buy mineral oil because I had to re-adjust a brake cable length on my rear brake, which is a Shimano M6000 Deore brake set. These worked great to refill and re-bleed the brake line, and feels just as good as the original mineral oil except much cheaper and is green color instead of red.
Review: excellent hydraulic mineral oil - I poked a little hole on the seal instead of removing the seal all together. Used it to top of brakes on an ebike I am converting - had to replace regular hydraulic brake with a one with motor cutoff line; that is why I needed this mineral oil to top of the fluid. Worked like a charm. Brake is responding crisply.

## Questions & Answers

**Q: What color is the fluid? I have heard some are green and some are pinkish. If both are mineral can I mix?**
A: The Finish Line fluid is a light green. Shimano and some others are red/pink. They are compatible as long as both are mineral oil based. I topped off my Shimano brakes with the Finish Line and have had no problems. The 120 ml bottle is enough  to flush both brakes if you want to.

**Q: Is this mineral oil compatible with Magura brakes?**
A: Magura probably recommends their own fluid, but I would try it. I can't imagine that it would cause a problem. I like it better than Shimano fluid in my Shimano XT brakes. Certainly don't use it in brakes that use DOT fluid.

**Q: Is this for mineral oil  bicycle hydraulics?**
A: Yes. But to be safe, please double check that your brakes use mineral oil. Using the wrong fluid can lead to brake failure.

**Q: service intervals?**
A: For me, I service my brakes every season of riding. Or if I notice my brakes feeling not the best to my standards, I service them accordingly.
