    Motul RBF600 + Elixir CR?

    I guess what I'm really asking is are there any Magnesium parts/pieces in the standard Elixir CR? While I'm asking, what about 2008 Codes? Any Mg bits in there?

    Don't know about magnesium content other than I've seen you can get mag levers on some CR models...but it was the title that drew me in, does Motul spontaneously combust with magnesium or something?

    Searching RBF600 led to this nugget

This will lead to a very spongy pedal and if let go may eventually generate enough pressures to lock the brakes.

    And it says not to on the bottle.

    though my particular bottle makes no mention of issues with exposure to Mg.

    You are not supposed to run RBF600 with magnesium components... as you saw in my post. And I think I did pull that little excerpt from a online store.

    I do not believe the standard CR has magnesium. But there is the CR Mag which does use a Mg lever body.

    Here are some results that turned up when I searched.

    According to the Audi forum and a certain individual who contacted Motul France, and Canada directly, it appears RBF600 is compatible with all OEM brake systems, even those containing Mg.




    "ANOTHER UPDATE on Motul RBF 600 please read on...

    --------------------------------------------------------------------------------

    Here is what I know and what I found out today.

    Source One, Tech rep from Motul France (yes, I called them directly from London).

    "He says that if the car was built with magnesium components from the factory, there is no problem with the use of the RBF 600. Oils were all tested and meet all the norms."

    Source two, Tech rep from Motul Canada
    (yes again, I called Canada from England)
    Someone is going to owe me big time for these calls!

    Same answer as above and he said "I will e mail the engineers at the factory in France to verify that there is no problem with the RBF 600 with cars like yours that may contain some magnesium in them."

    Generally speaking our entire line of brake fluid products, DOT 3, DOT 4, DOT 5.1 and RBF 600 are compatible with aluminium/magnesium alloys. The RBF 600 an cause compatibility problems with alloys made of high contents of magnesium, read almost pure Mg.
    Interesting.

    I'm glad to hear this. I have a bottle of Motul left over from my car racing days, and I was planning on using it with my XX's when it comes time to bleed.
