While I haven't heard too much about the high rate of moisture absorption of Motul, I've read about having to change it more often. However I'd bet that is due to the "normal" use that people who actually use Motul are subjecting the fluid to(track days etc). Here is a thread about it on H-T(the dealership/source is well respected in the NSX community):

I'd say sticking with the Motul over long periods of time is just fine for 99% of the people out there. But if you are road coursing it time after time, I'd change it more often.. Like you would with ANY fluid. So no loss if you ask me.

Please also keep in mind the high performance fluids that absorb water more quickly will also hold that moisture down in the brake calipers causing the internals to rust much more quickly.

It requires more frequent change than traditional brake fluid due to being more hygroscopic.

OK, so I will either run off the shelf crap, or Valvoline Syn if it's not that much more expensive.

Thanks everyone.

Once a bottle of brake fluid is open whatever you don't use right away is as good as junk and should just be tossed (if you care about keeping your braking system 100%) since it sits there on the shelf absorbing moisture from the air now inside the container. Yes this it nitpicky; please see my user title :)

In the event I don't use the whole bottle right away (~ 1 month) I consider it just regular brake fluid and pour it in any car that needs some.

What ryan meant to say was any of the lesser domestic vehicles in his driveway :)

When I replace master/slave/flex line for the clutch setup, I always clean the hard lines out, and then use DOT5 synthetic, good enough for motorcycles, good enough for me....anyone use DOT5 here?
