The air conditioner gas of VW Golf Mk2 uses "R12". But recently, it is difficult to get "R12" gas because no manufacturer provides new "R12" gas. (Currently, most countries forbid the usage of "R12" because "R12" contains CFC which despoils the environment.) So my mk2 uses "Auto Air Conditioner, Conversion Kit" and can use "R134a" gas.


Now, I got a WAKO's PAC compressor oil for R134a. It reduce friction in the compressor and improve the sealing of gaps.
