What to Do If the Car's Fuel Consumption Is Too High?

[DeBrynlee]

Here are the solutions for excessive car fuel consumption: 1. Clean the engine carbon deposits: Excessive carbon deposits in the engine are a major cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. After cleaning, it is best to drive the car at high speed for a while, which helps increase exhaust flow and allows stronger airflow to remove larger carbon deposit particles. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. When the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases during driving, and the sensor should be replaced at this time. 3. Regularly replace the three filters: During the use of the vehicle, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, it will affect performance, send incorrect information to the engine control unit, result in incomplete fuel combustion, and increase engine carbon deposits.

I've been driving for over a decade. If you're experiencing high fuel consumption, first check your driving habits. Avoid sudden acceleration and hard braking, try smoothly applying the throttle and maintaining steady speeds on highways. Checking tire pressure is crucial - inflate to the recommended level if low, it saves significant fuel. Don't neglect changing the air filter; a dirty one makes the engine work harder wasting fuel. Replace worn spark plugs too, as poor ignition leads to incomplete fuel combustion. Remove unnecessary items from your car - extra weight increases fuel consumption. Always refuel at reputable gas stations to avoid engine damage from low-quality fuel. Stick to regular maintenance schedules, including carbon deposit cleaning and throttle body maintenance. Use air conditioning wisely, employing internal circulation on highways for better efficiency. Remember, monthly vehicle checks help detect issues early, saving both money and hassle in the long run for a more economical and worry-free driving experience.
