Apparatus and method for changing oil in an internal combustion engine and simultaneously determining engine oil consumption and wear

摘要

A method and apparatus for changing oil and measuring oil consumption in an internal combustion engine having an internal oil lubrication distribution passage system with an oil filter and oil reservoir which includes the steps of connecting an external, separable apparatus to the internal oil lubrication distribution system at a first point upstream of the oil filter and at a second point in fluid communication with the oil reservoir; removing spent oil from the oil reservoir and measuring the amount removed; introducing a measured amount of fresh oil appropriate for the internal combustion engine into the oil reservoir; and calculating the difference between the amount of fresh oil introduced to and the spent oil removed from the oil reservoir.
