An oil in air test apparatus measures the quantity of oil vapor entrained in the air stream from an air compressor used to generate compressed air for a vehicle air brake system. Testing is accomplished while the air compressor is in service and mounted onto the engine of the vehicle. The test apparatus creates back pressure to simulate an operating load on the air compressor, and passes an air stream through a disposable oil in air indicator cartridge to capture oil entrained in the air stream. Visual examination of the indicator cartridge is utilized to determine the operation condition of the air compressor. The test apparatus allows the operator to determine whether or not the quantity of oil vapor carried over in the compressed air is within acceptable warranty tolerances. As a result, unnecessary warranty calls for air compressors which are passing oil within normal tolerances are prevented.
