What are the reasons for the high fuel consumption of the Besturn B50?
1 Answers
The reasons for the high fuel consumption of the Besturn B70 include abnormal tire pressure or switching to larger-sized tires; not turning off the engine during prolonged idling or frequent ignition; aggressive acceleration and frequent braking while driving; driving at high speeds in low gears or low speeds in high gears; fully opening windows in summer or using air conditioning in traffic jams; not planning the route properly, driving on congested roads, and frequently changing lanes. The following are methods to reduce fuel consumption: Cleaning engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, 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. Checking the oxygen sensor: As an internal control unit of the car, the oxygen sensor primarily 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. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas during driving, and the oxygen sensor should be replaced at this time. Regularly replacing the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If not replaced for a long time, they become dirty and clogged, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased carbon deposits in the engine. Checking the electronic control unit: Although the engine's electronic control unit is highly reliable, in older vehicles, various faults may inevitably occur.
