It takes about 2-1/2 500mL bottles. Shelf life of an unopened bottle is indefinite. I wouldn't use an opened bottle again after a few days as the fluid starts to absorb moisture from the atmosphere. Quality brake fluid is packaged and sealed in an inert dry nitrogen atmosphere. The cheap stuff is packaged in air (not good!).
