I'll just order some tomorrow to make sure I don't mix them up, it's pretty cheap for how helpful it could wind up being.

I think I'll test out those oil checkers too while I'm at it, can't argue with $7.50 after shipping. I know for a fact my system is pretty done at the moment, though it still works for a week or so if you add some freeon, so I can test one knowing it should come up bad. Another tool to make sure I get the system as close to its condition out of the factory. Not having AC is actually even crappier in the winter months (in my opinion) while living in PA. I can stand pretty hot temperatures without much complaint, but it's so difficult to defog the windows in cold weather without a functioning compressor.
The compressor doesn't run if it's under 36° anyway
