Abstract: A disposable oil absorbent pad assembly adapted for suspension under a vehicle to collect oil, grease and hydraulic fluids, comprises a bottom layer of a metallic screen material, an intermediate layer of insulating material and a top layer of oil absorbent material. A binder peripherally secures and interconnects the layers throughout their entire outer peripheries, and grommets extend through corner portions of the assembled layers adapted to receive fasteners for suspending the pad assembly from the underside of a vehicle.
