Maintain proper oil return through proper pipe. too much oil in a compressor can be caused by overcharging the system with oil, excessive oil carryover from the evaporator, or inefficient. As a lower amount of liquid refrigerant is required to saturate the oil, the rest of the refrigerant will expand and evaporate into vapor. oil foaming will appear and a combination of oil and refrigerant can be forced around piston rings and be pumped. keep the oil from overheating, and keep the compressor from “throwing” oil by preventing flooding.
