Does new unused anti-freeze 'age'/deteriorate??
I have 4 gals of antifreeze I have had for several years (6+?).
Unopened. all Prestone, 2 diff. types. Anyone know if it loses soemthing
while it sits in the bottle??
Also, 2 of these are Prestone in a black bottle, SCA pre charged, low silicate, penray technology.. Is this OK for a PSD?
The other two are yellow bottle, plain green contents..
Can I mix the two when I change my antifreeze??
Thank for your help. If these are still good, it will save me big bucks
in replacing my antifreeze.
