What are the reasons for the high fuel consumption of Besturn B50?

[Santiago]

Here are the reasons and solutions for the high fuel consumption of Besturn B50, as detailed below: Different driving techniques: The same car driven by different people will have different fuel consumption. Solution: Only by summarizing experience and improving driving skills can the high fuel consumption caused by driving techniques be resolved. High-voltage line issues: Causes abnormal ignition circuit. Solution: Can be resolved by inspection and replacement of parts to reduce high fuel consumption. Brake system issues: Brake pads not returning, increasing driving resistance. Solution: Can be resolved through inspection and restoration to reduce fuel consumption. Clogged fuel system: Carbon deposits causing blockages. Solution: Using fuel system cleaner to clean the injectors and throttle body can reduce fuel consumption. Dirty air filter: Restricted airflow, leading to incorrect fuel-air ratio. Solution: Needs to be resolved by replacing the filter.

I've been driving a Besturn B50 for three years. Previously, the fuel consumption suddenly soared to over 10 liters per 100 kilometers. After checking around, I found the main issue was my aggressive driving style—always accelerating and braking sharply. Later, by gradually changing my habits, the situation improved significantly. Additionally, inadequate maintenance also had a big impact. For example, when my spark plugs aged and weren't replaced in time, the ignition efficiency dropped, leading to wasted fuel. A clogged air filter can also increase the engine's burden, so it's recommended to check it every 5,000 kilometers. Insufficient tire pressure increases friction, directly raising fuel consumption, making monthly tire pressure checks quite necessary. Carrying too much stuff in the car or always running the AC also consumes more fuel, especially in summer when the AC is frequently on. Now, I try to minimize clutter, close the windows, and use natural ventilation. Lastly, if it's a mechanical issue, like a faulty oxygen sensor, it's best to get it fixed immediately—don't delay to save small money only to spend big later.
