1. A deterioration diagnosis apparatus for a mechanical apparatus comprising a gear, the deterioration diagnosis apparatus comprising:
a storage that stores a trend of change during operation of the mechanical apparatus in a consumption rate of an additive contained in lubricant used for the gear; and
a computer or circuitry configured to perform operations comprising:
reading, from the storage, the trend of change; and
determining a period to be taken for the consumption rate of the additive to reach a predetermined value, based on the trend of change in the consumption rate of the additive.
