Mineral Clutch Oil?

Canada280i · 03-11-2013, 12:00 PM

The clutch master on my bike indicates "mineral oil only" so does this mean any "mineral" based oil can be used. I cannot find anything specifically for motorbike clutch use locatally that is "mineral". I did find Castrol EP90 mineral oil, will that do?

Thanks for any and all advice!

I use DOT 5 in my clutch Master Cylinder, works a treat not that hard to find even at automotive places. Mineral brake oil is not just any mineral oil, I have been told, by Magura (made hydraulic brakes for my trials bicycle) but I don't know.

I would pump DOT 5 from bottom, to push mineral out to reservoir, remove from reservoir with towels or dumping it of course. Not too worried, but I dont know how critical having both in there at same time is/would be.

My Beta trials uses Brake fluid in both the front brake and the clutch.

My KTM does not. KTM requires mineral oil in the clutch system. -- there have been many post that putting Brake fluid in a KTM Clutch it wil require a rebuild in short order.

It is common practice to use syntetic fork oil in place of mineral oil. It is said the fork oil is less prone to cause crossion in the alumnium master/slave. They say use as thin as fork oil as you can get (5 weight). I have used 15w and the clutch did not feal too stiff. I have been running fork oil in both of my KTM clutches for years with no issues.

Use Dot 5 in clutch and both brakes. Makes it easy to remember.

I just bought some mineral brake fluid at a mountain bike shop, seems most of them use the mineral type of fluid in the brakes. No too sure how it is for absorbing water compared to dot 4 or 5 but it does not seem to mix well.

I was able to get Magura from a local CycleGear. http://www.cyclegear.com/

Welp, Gasgas doesnt use magura, only reason mentioned it was I had asked a guy at Magura... (which confused people I guess)

Dot5 in GASGAS 04-13 Pro will be ok, it is an OPTION if you want to. Else go find Mineral Oil Based BRAKE FLUID. your choices, from experiences. Shared freely just because, I hate people having to fight stupid little things, when they could be practicing...

anything else you try, you are on your own dont complain about me or about gasgas, just Sayin.

Magura Blood mineral oil works just fine.

Just to update, I found some mineral fork oil locally and had read that it was acceptable. I back bled from the banjo bolt uo to push out all of the old stuff and the difference is amazing. Not sure if there may have been the wrong oil or air bubbles in the system but it is now nice and smooth and drag less so I am happy with the result.

So what oil did you use?

I wonder if he mistyped, "fork oil"?

Canada280i · 03-26-2013, 09:27 AM
