Just wanted to know, if bottle is unopened, is it safe to keep motul rbf600 brake fluid? They say they pack it with nitrogen to prevent moisture absorption.

 

I'd guess it's no different than being on the store's shelf provided there are no real temperature swings where it's kept. Maybe the question to ask is what's the shelf life? Is there a "use by" date stamped somewhere? Is there a vacuum seal under the cap?
