Abstract: A mobile oil change cart for a sewing machine or the like. The cart has a generally rectangular parallelepiped shape whose upper surface defines a work surface for supporting the sewing machine. The upper work surface includes a rubber mat on which the machine can be placed and which prevents the machine from sliding about. Adjacent to the rubber mat is a recessed sink for containing fluids which may be spilled from the sewing machine during maintenance. A rack across the surface of the sink supports the sewing machine while draining the oil from the machine. Wheels mounted to the lower surface of the cart permit it to be easily moved from one work station to another. Underneath the work surface is a tank compartment for receiving and storing both fresh and waste oil. In addition, the tank compartment also includes pump means for both delivering fresh oil to the sewing machine and retrieving waste oil from the sewing machine.
