Or, it may be old stock and they were trying to warm people not to use
household freon in it back in the day when those were the two choices.

In any event, they are all the same is what I have been told by many
an experience AC technician. Not to worry. When you add oil, the only
oil you will be able to buy is the oil you need.

I have converted about six (soon to be seven) auto AC systems to 134,
never changed a compressor nor was I ever warned to.

It has a sticker on it that says "R12" and thats it-so is it safe to assume it is NOT compatible with R134? In which case it is going back, I never would have purchased a an R12 only compressor! Any have any experience with this?

They did not change the compressor, but rather cleared the system with a solvent for the purpose, and used the new R134a compatible oil.  I would discuss the matter with the vendor and perhaps the manufacturer.   R134a is a higher pressure gas than is R12, and a compressor special for it might run at higher pressure.  But my system cools well.

Almost all of them are labeled "Dry Clean Only."  But, I learned from my mother, who learned from her mother how to wash clothes.  I doubt my grandmother, and certainly not her grandmother, ever took anything to a dry cleaning establishment.  Good luck.  mcneely
