Recently, according to the strengthening of fuel efficiency targets, the increased environmental consciousness and the technology innovation, the fuel efficiency of new car improved every year. However, the mileage in a real drive by users does not match the nominal mileage measured by the manufacturer. That is because the actual fuel consumption is according to the driving environment, the attributes of the vehicles and travel distance. To grasp how these factors affect the mileage is necessary. Previous studies on mileage using large scale official data are very few in Japan. Based on such a backdrop, in this study, we use the data of fuel consumption survey by MLIT continued from 2006 to analysis the effect of the driving environment, the attributes of the vehicles and travel distance on mileage of gasoline vehicle and diesel vehicle.
