    First time owning a KTM (690E) and noticed hydraulic cluch mc is filled with dirty crap, so time for change. MINERAL OIL only it says. Being my first bike that calls for that....what recommendations or whate exactly constitutes mineral oil? Is this something I can get at local auto store? I hope so.

    Way back when I was turning wrenches on brit cars, some Rolls and Jaguars used a Castrol "hydraulic system mineral oil" (HSMO for short) so I suspect that is what you need but I would verify with KTM as it will be expensive if it required something different.

    Baby oil is mineral oil, have used it in my ktm dirtbike with no problems. Super cheap too. Just be sure to get the plain 100 percent mineral oil type.

    Good bicycle shops will have the proper mineral oil as well - magura bicycle brakes (and others) use mineral oil. I've also heard that babyoil works well, but so far have only used the official stuff intended for my mechanical babies :deal

    The clutch is a Magura item so officially you should use Magura oil but any SAE 5 mineral oil will do, I've used engine oil and anything I could find when neccessary. The only reason it's a mineral oil is to prevent gearbox contamination when the slave cylinder eventually leaks so don't get too hung up about it.
    I haven't tried the baby oil but lots of riders use it very happily.

    That's called Magura Blood.

    A lot of 950/990 owners (with the same clutch requirements) use shock/fork oil. I just bled my clutch this morning with maxima lightweight shock oil. No problems with it in the last 25,000 miles. something around 2.5-5 weight is ideal.

    Or...I could go to the BMW shop and pay $50 for the same bottle of $3 mineral oil because it has the BMW name (or KTM name) and feel proud because I have a brand name mineral oil on my shelf next to my Klim and superubber expensive BMW matching riding gear and Arai helmet.

    Does that mean the mineral oil from a drug store would work as well?

    ATF, any kind, works just fine. I've used it in KTM and BMW systems...

    exactly.

    I bought my magura blood at cyclegear for $18. 2 pint(?) bottle will last me forever even with 2 ktm bikes. I really like magura clutch masters over brembo masters.

    5W fork oil works great and, being something that you would have around if you keep your forks maintained is very handy too.

    Its perfect for the job. 2nd choice would be ATF if you have an auto car or ever top up your power steering. Some say a lighter fork oil works even better.

    Cheers

    Yep I'm more confused then ever who knew there were all kinds of Mineral Oil....LOL

    My Wife being a Pharmacist got me some that is 100%, She could get it in light or heavy...I got heavy because I assumed that would be it. Light is like water, runnier then Brake Fluid. I have not opened the bottle yet but she said its slightly heavier then babyoil.

    Good thing it's $6 for 16 OZ....so I'm not out much should it not be the right deal.

    I read some things that say the Pharmacy Mineral Oil is heavier...however my wife tried to find out the weight of the light or heavy and had no luck so not sure where people are finding the weights of Pharmaceutical grade mineral oil when not even the manufactures list it or know. (People pulling stuff out of their butts perhaps?)

    The stuff I got:
    Mineral Oil USP
    Paddock Laboratories, Inc

    I got my 99.9% mineral oil from the local Walmart pharmacy. Apparently also advertised to work as a lubricant/laxative! No problems with my KTM690e clutch...

    But then I don't use the official Motorex oil, but comparable SL-2 from Castrol for $10 cheaper a quart. So nice not worrying about the warrantee :D

    I have some that I brought home from work. It's a USDA registered food-grade White Mineral Oil that is used in the oil reservoir of fire hydrants. I thought that I would try it in the hyd. clutch of my ST when I changed the fluid in it, but that ended up calling for DOT 3/4 brake fluid. I usually keep some of the hydrant oil around the house because it works well on a rag for wiping down guns after handling them.

    One thing I should mention some might not know Mineral Oil can break down if exposed to light, The Pharmaceutical one I got is in a solid white container thus not being exposed to light.
