I have a 94 integra gsr. I replace and bought a new ac compressor. The new compressor said must add oil before use. I look at Helm's manual but didn't find how much and where to add the oil. There are 2 ports on top of the compressor. Dont know if oil goes in one of the port or not.

Also where to buy PAG oil for the compressor? Check advanced but didn't have them.

Thanks in Advanced
