On original RV2 compressor, there is a sump that holds oil and needs to be filled with proper amount (see factory service manual). On the passenger (right) side of the compressor, there is a cap that you can remove to fill the sump - think of compressor as a 2cylinder V engine, and then look at FSM to see what is needed for proper fill. The FSM shows you how to use a dipstick for the proper fill. Then from there you or your ac tech can do the vacuum test and pull any further amount of oil into the system.
