    Hehe I was about to ask the same. I'd say yes, but I'd like a confirmation.

    they all recommend their own products, I ve used finish line in shimano without issues
    there are minor differences in them. I feel pretty safe using any bike brake mineral oil, I wouldn't use medicinal mineral oil though

    Why not medicinal mineral oil?

    The United States Pharmacecopeia controls all those variables

    Where do you think Shimano and Magura get it from

    they may be controlled, but they aren't aiming for the same standards.

    quote from Magura:
    "Magura Blood mineral oil is the recommended oil, which is a 10 weight mineral oil. By far, our most common problem we encounter is consumers putting off-the-shelf mineral oil (from a drug store) in their Magura hydraulic brakes. Off-the-shelf mineral oil is normally 30-50 weight which will make the brake very sluggish. In addition, off-the-shelf mineral oil has additives, perfumes and different boiling points, all of which can cause brake failure."

    exactly right
    why bother, if you shop around you can get a liter for not much $$ and it will last years
    people crack me up, they'll spend $300 for high end brakes and then try to cheap out and save $10 on oil

    heres a liter for $20

    I've used this on my Shimanos:
    Mineral oil hydraulic fluid for German cars.
    Don't use drug store oil as that stuff is too thick. Even if it doesn't break anything, it's too thick for a good firm and free lever feel.

    yes...the standards are much higher....

    Oh, and you would find mineral oil in the USP National Formulary sections, its a separate book from the USP..

    my comment on "standards" has nothing to do with quality and purity, but that they obviously aren't trying to make the same product if this medical mineral oil is so much thicker than what is recommended by Shimano and Magura

    +1

    got a quarts worth for 25$ from the local bmw dealership.

    I find it copes with cold weather better than the shimano mineral oil.

    Yep, Pentosin CHF and ATE Racing Super Blue fluids are not only compatible for motorcycles and German sports cars...but work great for mineral oil based MTB hydros too.

    At a 536 + degrees boiling point - the fluids far exceed what our brakes will ever get. I use them with zero fade on the steepest DH. ATE makes a gold and blue fluid(same exact formulas) so brake bleeds can be unmistakingly perfect every time.

    ATE is a brake fluid and isn't supposed to be used in Shimano brakes.

    Yeah ATE super blue is a dot4 fluid.

    Pentosin CHF 7.1 "Central Hydraulic Fluid" is a high performance mineral based hydraulic oil for power steering etc and that works perfectly with shimano hydros.

    My bad...I used ATE on my Juicy Ultimates, but use Pentosin CHF on the Magura Marta SL.
