A method for diagnosing a lubricant containing an additive, is executed by an information processor. Chromaticity information of the lubricant which is a diagnosis target is obtained from an input device, the chromaticity information is obtained by an optical sensor, and a storage device stores a deterioration curve of the lubricant which is the diagnosis target, the deterioration curve is determined in advance regarding a transition in a chromaticity coordinate caused by a deterioration, and a chromaticity coordinate corresponding to a limit contamination level determined in advance using a contaminated lubricant. The processing device obtains a chromaticity coordinate of the lubricant from the chromaticity information and uses a relative contamination level obtained from a distance of the chromaticity coordinate of the lubricant from the deterioration curve and a distance of the chromaticity coordinate corresponding to the limit contamination level from the deterioration curve.
