A concentration sensor 100 that detects the residual amount of the entire mixed fuel, which is provided in the fuel tank, and a first level detection means 200 that is provided in the fuel tank and detects the remaining amount of the entire mixed fuel; a second level detection means 300 for detecting the remaining amount of the mixed fuel; and a detection value of the first level detection means 200 and the concentration sensor 1 when the mixed fuel is not phase separated.
The remaining amount of each mixed fuel in the fuel tank is calculated based on the detected value of 00 , and when the mixed fuel is phase separated, it is calculated based on the detected value of the first level detecting means 200 and the detected value of the second level detecting means 300 . Remaining amount calculating means 400 that calculates the remaining amount of each individual mixed fuel in the fuel tank; Mileage calculating means 500 that calculates the possible travel distance of the vehicle from the calculated remaining amount of each mixed fuel; and the calculated remaining amount of the mixed fuel. Display means 6 for displaying distance
A fuel remaining amount display device comprising: 00 and 00.
