I had a car with 10 year old hydraulic clutch fluid in it. Even though the clutch worked fine, I pulled in fresh fluid just in case. Sure enough, within one drive the new fluid completely destroyed the seals in both the master and slave.

So, if you're planning to bleed a car with really stale fluid, be ready to do all the hydraulic parts too and start completely fresh, otherwise you might just leave it as-is if its working.
