PROBLEM TO BE SOLVED: To provide oil supply information including an economic viewpoint in consideration of a fuel consumption resulting from a quality of fuel different for each stand.SOLUTION: In a navigation device, estimated fuel consumption calculating means acquires fuel consumption statistical information from a center (S410), and calculates the estimated fuel consumption for each kind of oil for each stand based on the real fuel consumption in a vehicle (S420). Oil supply information including the estimated fuel consumption calculated by the estimated fuel consumption calculating means is displayed (S430). In other words, the estimated fuel consumption for each stand is calculated based on the fuel consumption statistical information, and thereby, the oil supply information including the estimated fuel consumption is provided. |
