Most systems take about five ounces. That's what they come with brand new. Oil being a liquid, stays in there even if the "Freon" (134a) sometimes leaks out because it's a gas. You don't have to "change the oil" or add any unless you replaced a major component that would contain that oil like the compressor, accumulator, evaporator, or condenser.
