Oil Compatibility
 

My front brake is this "Shimano Deore BR-M486", the original Mineral Oil is almost a light pink color as this in the figure.

Today i bought a bottle of mineral oil of the brand "CYCLO TOOLS" but sadly i noticed the color is not the same only when i was in my home. This particularly product had a greenish color.

Is that compatible for my shimano brake?
Have a good day!

DOT Brake Fluid vs. Mineral Oil - and the Winner is.. | Epic Bleed Solutions

It's not the colour. It's the composition.

Basically DOT fluid is properly characterised. Mineral fluid is not. As a result you are in wet finger territory. If you put it down to marketing then you can mix Cyclo with Shimano. Otherwise you have to completely clean out any of the original Shimano before replacing with Cyclo. That still leaves you with the Shimano claim that only their stuff is optimised to work with their brakes, not necessarily a wild claim... or you can trust the Cyclo to be good to go, why sell something that does not work?

I'm just having a ramble because I do not have hydraulic brakes or any experience of them. FWIW if they came with Shimano fluid and the price differential, considering rate of usage, does not hurt the pocket then I would stick with the Shimano 'lock in'. I do not know if there might be a warranty issue.

My first move would be to contact CYCLO and ask them the same question. Chances are they can give you an answer since they don't want to get blamed for ruining your brakes. They may of course just say you can only use their product and don't mix it to sell their stuff but they may also give you an honest helpful answer. Color is meaningless in this case.

COLOR of oils is from a DYE... it has nothing to do with the composition of the oil.

viscosity and any actual additives are what is important.... and whether the oil is compatible with the seal materials used in the brake system.

As noted, the color is purely a dye added for recognition.

As long as the oils are of the same class and viscosity your system calls for, the color doesn't matter, and you can even mix and make your own color.
