Remove the plastic panel under your car and use the cardboard like Bob said. If you find oil on the passenger side of the car, its most likely your Valve cover gasket. If its on the driver's side, its most likely the oil filter housing gasket. Also, just to rule out major problems, check your coolant and see if there any discoloration that would indicate oil.
