When replacing compressor

Compressor oil is sealed in each new compressor by the amount required for A/C system. Therefore, when using a new compressor for replacement, drain excess oil from it by the amount calculated as follows.

"C" = "A" - "B" 

"C": Amount of oil to be drained

"A": Amount of oil sealed in a new compressor

"B": Amount of oil remaining in removed compressor
