Castrol SRF Synthetic Brake Fluid shelf life?

[dylanfan53]

So stored in a bottle on the shelf in an attached garage, how long before you'd throw it away?  Post away...

I used one bottle a year. I would toss what ever was left or save it for fellow competitors to borrow :)

I really liked it, was well worth the money.

Not sure about a 100 % concentration of brake fluid but I found this to be interesting:

'Cesium, as well as cesium-137, is a soft, malleable, silvery white metal. Cesium is one of only three metals that is a liquid near room temperature (83 °F). The half-life of cesium-137 is 30 years.  However, when mixed in a 50/50 concentration with Castrol SRF Synthetic Brake Fluid the half-life is reduced to 29 years.  It decays by emission of a beta particle and gamma rays to barium-137m.'
