Is Motul 660 ok to run in Formula RO brakes?
The info I'm finding says it fine, just want to be sure.

I guess the next question is if its necessary.

Thanks

Motul 660 is DOT4. Formula RO brakes require DOT4 fluid. so you're fine.

DOT4 systems are typically backwards compatible with DOT3 fluid. but not all DOT3 systems are compatible with DOT4 fluid.

Is it necessary? Do you have the cash? 660 is pretty premium. and formulated for AUTO racing, as its boiling point is pretty high. It's doubtful that you ever will NEED that sort of performance. but hey, if you got that cash or have some lying around leftover from filling your car, it'll work fine.
