Got a question for you wrench types... *cough* Peter, Kev... *cough*...

What is the shelf life of an opened container of say... tranny fluid or diff fluid??? I know brake fluid starts to go bad as soon as you open it but I am not so sure about the lubricant type fluids... Curious about motor oil, too...

 

The problem with brake fluid is that it is hydroscopic and will absorb water which will lower it's boiling point.

Petrolium based products like lubicating oils do not suffer the same fate.

I have never seen any limit to storing/keeping oils. I used some 2yr old anti-freeze the other day.

 

Then you are free for a promotion. Problem solved again.

 

Hydroscopic...

I was trying to remember that word...

 

How's life in the Mid-A?

 

Or HyDroscopic even.

 

Didn't anyone tell you??? I can't spell for oop:

 

ahh thank god for lunch time lol

 

I have kept sealed motor oil around for a looooooong time, but I was curious what to do with my left over tranny fluid.

In all honesty, it ain't really enough to even worry about. More than anything, I am just curious.

Thanks for the info, Pete!

 

Wow... You are allowed to eat??? Lucky dog... They usually just slide some bread and water under my cube wall every now and again...
