My BYD Song 1.5t is more than one yuan per kilometer on average, about 100 kilometers 15 yuan. Is this normal?

No, it's normal for this kind of car to consume about 89% fuel per 100 kilometers.

When driving, the fuel consumption of the car suddenly increased. Don't worry about repairing the car yet. You can find the cause first, such as carbon deposit on the accelerator, and then go to the 4S shop to clean it up. Replace the spark plug when the service life of the spark plug expires; Oxygen sensor failure, carbon canister solenoid valve failure, etc.

Fuel consumption per 100 kilometers = fuel consumption (liters) ÷ mileage (kilometers) × 100.

For example, if the fuel consumption is 100 kilometers, add 40 liters of oil at a time and run 500 kilometers, 40/500=0.08, 0.08* 100=8. The fuel consumption per 100 kilometers of a car is 8L, but it is often inaccurate through a manual calculation. It needs to be filled up three times to calculate the average, which is relatively more accurate.

Extended data:

Actual calculation method of fuel consumption per 100 kilometers: X/ 100=50/600, where x is the actual fuel consumption we require, and the right side of the equation is the fuel consumption of 50L when the vehicle travels 600 kilometers. Solve the equation, X=50× 100/600.

Answer: X≈8.33

Therefore, the actual fuel consumption of the car is about 8.33L per 100 kilometers.

It is stipulated that each cycle contains various driving power conditions, and the driving power conditions are recorded according to the indicators such as shift time, parking time, driving speed, acceleration, braking and deceleration specified in each cycle.
