Default UPDATE from Motul (translated)...

This is the answer we got from Motul France via Motul Canada to whom we asked the questions to. It comes directly from the Motul technical department.

" Yes certain brake fluids can cause compatibility problems with aluminium/magnesium alloys.

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 <b>high</b> contents of magnesium, read almost pure Mg.

To summarize, on OEM brake systems, all Motul brake fluids, including the RBF 600 are compatible. Certain Audi A3s came equipped with brake callipers made of magnesium alloy and Audi recommended using DOT 4 and we recommended, Motul DOT 4 or 5.1 for daily use.

On <b>special competition parts</b> be careful and try to find out what alloys are used in those parts. If in doubt use Motul 5.1 instead of the RBF 600."

The end.

Default Sure 5.1 is safe. If you are using "aftermarket" brake components and you're not sure what type...

Or amount of magnesium alloy is used in these componenets, then RBF 600 may not be for you, use the 5.1. Anyone using Stoptech, AP Racing or Alcon calipers should perhaps check with those manufacturers before using RBF 600 to see if some of their components have a high amount or quantity of Mg in their systems. I can tell you my friends have been racing with AP Racing calipers on some of their cars for years and have yet to have problems with the RBF 600.

One more thing I forgot to mention in the translation.
All Porsche brakes systems are safe to be used with the RBF 600. Since the Porsche one piece aluminium monoblock calipers are built by Brembo, one would think that the Brembo calipers are also safe to be used with the RBF 600 brake fluid.

Do we know what the S4 brakes are made of? I know they are monoblock.

Default According to Motul, "ALL" Audi production parts, read OEM brakes are compatible with the RBF 600...

The only exception was a certain amount of A3s that came equipped with calipers with some Mg contents. Audi recommended to use DOT 4 for those cars as a preventive measure.
