Hi Rizwan ,
Usually the amount of oil in circulation will be 1 to 3% of the mass flow .

Any thing above should be unusual & should be investigated why ......... reasons could be :
a) liquid carry-over to copressor b) suction filter of suction service valve partially blocked whereby the crank-case pressure is lower than suction pressure c) worn out piston rings d) refrigeration piping faulty e) low load / low head pressure
HOW MUCH OIL IS ADDED IN SYSTEM ...... ? QUALITY OF OIL BLACK/ CONTAMINATED .... ?
These are general issues for oil loss / oil not returning
