Colorado
I have a 34 year old tractor with pretty low hours and the original AC system with R12.
It has gotten a little low on refrigerant and I would like to top it off rather than convert it.
Ive found several R12 substitutes, however they are all a little confusing in their wording, its not clear if you can mix them with R12.
Wondering what other people have done.
R12 AC system top off?
