Old Stock - Slick 50 Transmission Additive
 

Hi everyone -
I'm going through the stuff at my old house/shop and finding all sorts of things I forgot I had...

One of these items are several cases (6/1) of Slick 50 Transmission Additive.
2 cases of automatic, 1 of manual.

These are probably 15/20 years old and unopened...
Thoughts...??
Do you think this is any good still? (as far as time effects of storage on the materials in the bottles).

On a side note - I did use their Auto Trans additive in our old 1995 Explorer. The truck lasted through 200k with no issues - transmission or engine for that matter... (I used Mob 1 10W30 in the engine... :) )

Is it any good still? No.

Was it any good when it was made? Also no :P
