Fill engine with oil to full mark. Raise car, put on stands and use flashlight (engine running, in park) and inspect the engine for leaks.
Depending on where the leak is (rear main seal, for example) it could be very expensive.
If you cannot find leak, then there is a dye you can add to oil to isolate leak.
Look at front and rear main seals, valve cover, oil pressure sender, oil pan gasket, oil filter and oil drian plug.
