What is the shelf life of unopened gallon of DOT 5 brake fluid. I just got a gallon of NOS, dated 1994. Is it safe to use? (And yes, I did search and couldn't find anything.)

Dot-5
As long as the cap is on it should last for longer than you and I will ever be around. Since its silicone it doesn't attract moisture but once the cap is off there's no telling what else could end up in there. I've used DOT-5 in new un-opened cans with dates all the way back to the 1970's and had no issues.. Good luck.

Does anyone have the Lot number or contact number of the bad lot of DOT-5 silicone fluid that was IDed by the Gov and put out in a safety memo years ago??
TIA
Disregard, I found it, dated June 1997, "Report of Contaminated Brake Fluid, Silicone, NSN 9510-01-102-9455, DLA 400-87-C-5392, All Lots, DOW Corning Corp". Doing a brake job on the duce and found a few gallon jugs of the silicone DOT-5 purchased years ago at Aberdeen Show. The message goes on to say "all subject brake fluid manufactured prior to Jan 88, all manufacturers is considered to be unsatisfactory and should be disposed of"
Cheers!

Yeah, but you have to remember the Govt has more money than sense. We turn in expired HAZMAT now that we used to be able to extend at the unit level but now it's "order new stuff". As long as there aren't any contaminates it will be good.

I just buy fresh fluid. $73 for 12 a 12oz bottles free shipping. Easy to pour from small bottles than a gallon can and handy to keep a couple in the truck.

Rusty, I'm with you, the lot I have that was unopened has chunks in it, ran it through a paint strainer. Dow Corning batch 1gal container purchased at a show. With an AVN and Ordnance background, I agree the gov't does have deeper pockets, but every Safety of Use message I ever got usually ment some joe ran into a problem and passed it up the chain of command. After all the wheel cylinders ,flex brake lines I just replaced along with new seal & some bearings, think I will bite the bullet and purchase new fluid.

Doesn't dot5 turn yellow as it gets older being exposed to air? Would be a good way to tell if the container had a good seal or not if so.
