It has R134A in it at the moment, as put in by a 'proper engineer' nearly 3 years ago, which is what I'm going to top it up with. Leak stopper/Dye/Oil is put in seperately from another can.
In 3 years its gone from freezing to just cold, so not leaking much, and I don't help by not using it all winter. I have also nipped up a joint with a small amount of residue on it.
