How much oil do you put in the ac compressor when replacing it?

Answer 1

Amount of compressor replacement oilFrom what I've read in other AC Manuals and what I've practiced, with regards to the amount of refrigerant oil to add, is to add the same amount that you drain from the old compressor unit that you removed from your system. This amount, from my experience is about 5 oz, however, it varies from compressor to compressor. The most accurate way to asses this, short of contacting the compressor mfg, is to apply what I said in the first sentence.

add 6 ounces for a single ac system and 10 to 12 ounces for a vehicle w/rear air.(like surburbans, vans etc.)
