PROBLEM TO BE SOLVED: To provide a recommended oil supply quantity presenting device capable of preventing fuel degradation without causing degradation of fuel economy.SOLUTION: A recommended-oil-supply-quantity calculation unit 205 calculates planned fuel consumption quantity by which fuel is to be consumed within a degradation period in light of fuel consumption per unit period, and calculates a recommended maximum oil supply quantity on the basis of the planned fuel consumption quantity. A user-notification-information generation unit 206 outputs notification information for notifying a passenger of a message including the calculated recommended oil supply quantity. A user notification unit 210 displays the message including the recommended oil supply quantity on the basis of the notification information output from the user-notification-information generation unit 206. With this configuration, the passenger can be notified of an appropriate oil quantity by which the oil can be used up without causing fuel degradation. Thereby, degradation of fuel can be prevented without causing degradation of fuel economy by supplying fuel in accordance with the notified recommended oil supply quantity. |
