Re: refrigerant oil, how much?

["jtrealtywebspannet" <jtrealty@xxxx>]

It is really hard to say just exactly how much oil should be in each 
component. It depends on how many times the system has been refilled 
with freon, if it is leaky, if it is stored etc. In general you can 
ignore the minor amounts in everything except the compressor where 
most of the oil is anyway. The procedure for checking the amount of 
oil in the compressor is in your Workshop Manual N:10:03-:04. If you 
are replacing the compressor go to N:10:12. While it is true that the 
oil circulates around the system the bulk of the oil is supposed to 
stay in the compressor for the obvious reason, lubrication of the 
moving parts. The other parts of the system don't require lubrication, 
they just allow the oil that escapes from the compressor to return to 
it. On the subject of refrigerent oil if you are checking the level 
two other very important things to check are color and PH. Color is 
easy, PH requires a test strip like you use on a pool. If you have a 
leaky system and moisture got in it wrecks the PH and will cause 
corrosion. In general it is best not to add oil but to just remove it 
all and replace with fresh that way PH isn't a concern and you are 
removing any dirt and contaminates. We are only talking about ounces 
here.
