After entering the "back to the South", the car often appeared unsmooth ignition. After opening several times, I also noticed that the fuel consumption of the vehicle was obviously higher than before. Ask a friend who is more familiar with the car, it is possible that the car is getting more and more gas consuming and the accelerator is not smooth. First, we should know some old drivers know that if the oil consumption suddenly increases, it is not normal, then we should go to the 4S store to check the car's oil road and circuit, because if steam is vapid When the car's oil circuit and circuit malfunction, the engine will increase when it works.
