Question: Why is the fuel consumption higher after car maintenance?

1. After washing the throttle, the carbon deposit is washed away, and the throttle opening becomes larger, which requires reprogramming by a professional computer. The throttle needs a certain self-adjustment process, which may lead to insufficient power.

2. Too much oil

Excessive addition of engine oil may also lead to insufficient power. Generally speaking, it will lead to an increase in fuel consumption.

3. Abnormal tire pressure or wrong tire size.

When tire inflation is insufficient, it will affect fuel consumption. When the tire pressure is too high or too low, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the vehicle will naturally waste more oil.

4. The tires are badly worn.

If the tire is badly worn, it will often slip and increase fuel consumption. At this time, consider replacing the tire with a new one.

5. The spark plug should be replaced.

If the spark plug is used for too long, the fuel consumption will also increase. Because the damage of spark plug will reduce the ignition energy and slow down the vehicle speed, resulting in a significant increase in fuel consumption.

6. Four-wheel alignment value

Maintaining the alignment value of the wheels can ensure a low fuel consumption rate.

7. Influence of environmental factors

Turning on the air conditioner in summer will directly increase fuel consumption, while not turning on the air conditioner to open the window for cooling and ventilation will also increase driving resistance and fuel consumption, especially when driving at high speed. Opening windows wastes more oil than opening air conditioners, and the environmental characteristics in winter will also lead to an increase in oil consumption.
