Lubricants commonly referred to as "multi-purpose" typically fulfill applications which have overlapping performance requirement ranges. For example; a heavy weight hydraulic oil may also serve well as a light weight gearbox oil and be called multi-purpose. This "multi-purpose" designation should not be misinterpreted as low quality or not being the best or most suitable for a particular application. It just happens to be suitable for more than one application given its properties.
