What are the reasons for the high fuel consumption of the Mazda3 Axela?
2 Answers
The high fuel consumption of the Mazda3 Axela is influenced by various factors, such as the driving habits of the owner and the internal performance of the vehicle. Below is a detailed analysis of the specific reasons for the high fuel consumption of the Mazda3 Axela: Excessive engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, primarily due to the use of unsuitable fuel. It is recommended to add a certain amount of fuel cleaner during refueling. If the effect is not noticeable, it indicates a high level of carbon deposits in the engine. In such cases, the vehicle must be taken to a 4S shop for professional cleaning of the engine carbon deposits by technicians. Damaged oxygen sensor: As an internal control unit of the vehicle, the oxygen sensor monitors the air-fuel ratio of the engine. Once damaged, it can cause an imbalance in the air-fuel ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases during driving. At this point, the oxygen sensor should be replaced.
I also experienced higher fuel consumption when driving the Mazda3 Axela. The main reasons include aggressive driving habits like frequent sudden acceleration and braking, prolonged idling in congested urban areas consuming more fuel; insufficient engine maintenance such as carbon buildup leading to incomplete combustion, and dirty air filters reducing intake efficiency; low tire pressure increasing rolling resistance and fuel consumption; poor fuel quality with many impurities affecting combustion efficiency, where higher-octane gasoline sometimes doesn't suit the engine and causes extra fuel injection. It's recommended to develop smooth acceleration habits, perform regular maintenance to clean carbon deposits and check tire pressure, and use the manufacturer-recommended fuel type for significant fuel efficiency improvement.
