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

[MacNadia]

The reasons for the high fuel consumption of the Besturn B50 are as follows: Severe carbon deposits: Poor fuel quality or frequent use of fuel additives can lead to increased carbon deposits inside the engine. Excessive carbon deposits can cause roughness inside the intake manifold, affecting the air intake volume and the mixture effect. If you notice an increase in vehicle fuel consumption accompanied by a decrease in power and acceleration shuddering, it is likely due to severe carbon deposits. Ignition system: Faulty ignition coils and spark plugs are common issues. A faulty ignition coil can cause the ignition system to malfunction, resulting in cylinder misfires, reduced power, and increased fuel consumption. Maintenance issues: Problems such as too much or too little engine oil, poor oil quality, excessive viscosity, or failure to change the oil on time can all contribute to increased engine fuel consumption.
