What are the reasons for the high fuel consumption of the Besturn B70?

[DeAlexandra]

Here are the specific reasons for the high fuel consumption of the Besturn B70: 1. Affected by temperature: Fluctuations in temperature can cause variations in fuel consumption. In winter, lower temperatures lead to increased fuel consumption. 2. Lack of vehicle maintenance: Dirty engine oil and air filters can also result in higher fuel consumption. Dirty oil leads to poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thereby raising fuel consumption. 3. Excessive carbon buildup in the vehicle: Carbon deposits commonly accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can cause incomplete combustion, leading to increased fuel consumption.
