[DML] Re: AC System oil



It seems no one wants to take a crack at my oil question, so I did 
some more research and learned a few things on my own.

My AC manual states that if a single part is being replaced, i.e. 
evaporator, condensor or accumulator, then a certain amount of oil 
should be placed in the new part. If everything is new, then all the 
oil goes in the compressor.

Since I effectively have a cleaned out system now, I decided to 
drain the compressor oil and see what was in there. I only had less 
than 2 ounces in the compressor. I suspect there may be a lot in the 
old accumulator, since it weighs 8 ounces more than the new one.

So, my plan is this: I am going to place 6 ounces of mineral oil in 
the compressor, and pour another 2 ounces down the line going to the 
condensor. That would put 8 ounces total in the system, which I 
figure should be about right. After evacuation I will charge with 36 
ounces of R12. 

Am I right in this line of reasoning, or is there something I have 
failed to consider? Any and all help welcomed.
