Re: IML: Air conditioning compressor "oil"

["Stevan Miner" <miner@xxxxxxxxxxx>]

Hi Brad,

There is indeed a separate oil for your AC compressor . It can be added either right into the compressor ( a small wire can act as a "dipstick") or the preferred method of injecting it right along with the freon through the low side service port. The system obviously would have to be completely discharged to add oil into the compressor itself. Oil in itself has nothing to do with the cooling of the system but is quite important for lubrication of the compressor. That is the main reason behind having a low pressure cut-out switch which shuts off the compressor when the freon charge runs low-no freon flowing, no oil-result possible compressor damage. Depending on whether the system is using R-12 or R134 determines the type of refrigerant oil needed. Unless you've had a major leak of freon and a subsequent loss of oil indicted by a wet oil spot around the affected area, oil is generally not needed as the system doesn't "use" oil as your engine can. Hope this helps explain a little better.

Subject: IML: Air conditioning compressor "oil"

I don?t want to sound stupid in asking this question but I am not mechanically talented.  I have read articles on the list server about ?checking? the ?oil? in the air conditioning compressor to keep it from locking up.  I have a 1968 car if that is important in your answer.  The A/C blows cold although I would like it to be colder.  Is there some kind of oil that is required in addition to the refrigerant?  I know refrigerant is installed under pressure.  Is there separate ?oil? that is added through a dip stick tube like a car?s motor would have?  Does it matter based on the kind of refrigerant I have?  I don?t want to damage my car but I asked a local car club member about it and he said there is no such thing for my car as separate ?oil?.  Thanks for any comments you might have to clarify my ignorance.  Ignorance is not bliss!!!!
