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 open windows in summer and using air conditioning in traffic jams; not planning the route properly, driving on congested roads, and frequent lane changes. The following are methods to reduce fuel consumption: Cleaning engine carbon deposits: Excessive engine carbon deposits are a significant reason, 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 high level of carbon deposits in the engine. In this case, the car must be taken to a 4S shop, where professional technicians will clean the carbon deposits in the engine. Checking the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the air-fuel ratio of the engine. Once it is damaged, it will cause an imbalance in the air-fuel ratio, and the fuel consumption will definitely increase suddenly. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases while driving. At this point, the oxygen sensor should be replaced. Regularly replacing the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If they are 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 engine carbon deposits. Checking the electronic control unit: Although the engine's electronic control unit is highly reliable, in older vehicles, various faults may inevitably occur.
