What to Do About High Car Fuel Consumption?

[DelAnderson]

Reasons and solutions for high car fuel consumption are as follows: 1. Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of inappropriate fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not obvious, it indicates a large amount of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional technicians to clean the carbon deposits inside the engine. After cleaning, it is best to drive the car at high speed for a while, as this helps to increase displacement 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 damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. If the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas while driving, and the oxygen 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 should be replaced regularly. If not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.

I often drive long distances and find that high car fuel consumption is mostly due to insufficient tire pressure or aggressive driving habits. Before each trip, I always check if the tire pressure meets the standard, as the value recommended in the manual is crucial. Regularly replacing the air filter can save a lot of fuel because a dirty one restricts air intake. While driving, avoid sudden acceleration and hard braking. I use cruise control to maintain a steady speed. Additionally, setting the air conditioning too high can also increase the load, especially in summer. Try using the external circulation mode and a moderate temperature. A heavy car body is also not fuel-efficient; clearing out unnecessary items from the trunk can help improve this. Overall, developing good maintenance habits and gentle driving will naturally reduce fuel consumption.

As an urban commuter, high fuel consumption has been a major monthly expense for me. I usually monitor fuel consumption through an app and notice a significant spike during traffic jams. The solution is to use ECO driving mode, starting slowly and maintaining a steady speed. In terms of vehicle maintenance, I clean the throttle body every quarter, which reduces engine load; switching to low rolling resistance tires also helps. Using air conditioning less and opting for seat ventilation saves more; choosing the right engine oil is crucial, as overly viscous oil increases resistance. In winter, don't warm up the car for too long—just a minute is enough. With these simple adjustments, fuel consumption has noticeably decreased, making my wallet happier.

Having worked in the automotive industry for a long time, I know that a sudden increase in fuel consumption may stem from oxygen sensor failure or fuel injector carbon buildup. Check if the tire pressure is too low—the standard value is printed on the door frame. Clean the air filter, as blockages can lead to insufficient air intake and increased fuel consumption. Routine maintenance includes regularly replacing spark plugs, as worn ones reduce ignition efficiency and consume fuel faster. While driving, avoid prolonged idling and rapid acceleration at high speeds. External factors like strong winds or uphill routes also affect fuel consumption, so planning smoother routes is advisable. Timely inspection and repair of these components can prevent abnormal fuel consumption.

Driving all day with kids in the car can be a headache when fuel consumption is high. I've developed a habit of checking my car's condition weekly, with insufficient tire pressure being the most common issue—topping it up saves fuel. Avoid driving too aggressively; start gently without stomping on the accelerator and maintain a steady speed within city limits. Don't crank the AC to max; use recirculation mode to reduce load. Clear out unnecessary items from the car to reduce weight and lower fuel consumption. In winter, drive at low speed for a few minutes after a cold start before accelerating. These small adjustments are both safe and cost-effective, making the family budget much easier to manage.
