An oil cleaning and recycling system (1) is provided for automatically metering a predetermined amount of engine lubricating oil into a diesel fuel supply of a diesel engine (88) as the engine (88) operates. A pump (10), communicating with a lubrication system of engine (88) and with a fuel tank (86), is intermittently operable in response to a regular, periodic signal generated by a control module (40). A control solenoid (36) admits air into pump (10) upon each such signal, thereby causing a piston (18) in the pump (10) to travel upwardly to discharge a preloaded amount of oil into a fuel return line (90) to produce a mixture subsequently consumed in the engine (88) as fuel. The pump (10) is provided with an air-actuated valve assembly (22) to direct flow of oil into and out of a cylinder (12) and with an indicator rod (20) enabling a user to visually determine that the system (1) is in working condition. The system (1) also includes a testing mechanism, including a button (82), manually activating the system (1) to confirm that it is in working condition prior to operation during transit.
