I have a couple bottles of ATE Super Blue sitting in the closet. They have been sitting around for about a year now but are unopened and sealed in original packaging. I just wanted to double check and see if anyone thinks this fluid could have gone bad. I doubt it is bad since it has not had the chance to absorb any water from the air.
Yeah if they're opened, I believe the shelf life is like 1-3 months if that...it begins to collect teh moisture
One thing that has me curious, though. Why would an opened can be worse than the stuff in my car? In my car, there's the filler cap plus the tubing for water to seep in. In my can in my house, there's the (smaller) open cap, in a less humid environment, in a can.
There is nothing different about it. If you go to a different fluid (ala Blue, Motul, etc...) you really should be changing your fluid every 6 months or so.
I suppose its because I'm paying $10+ / liter to have a can of "fresh" fluid, and when it goes in the car...I expect to pour in exactly what I paid for.
Oh, yeah, when I open the can, I expect it to be awesome. But, what if I need to bleed the brakes? I'm gonna bleed 'em, even if I have to open a can. Then, I'm gonna keep the can and use it. Maybe, I should put it in the gun safe with the dessicant.
