What are the reasons for the high fuel consumption of Citroen C4L?

[Melanie]

There are several reasons for the high fuel consumption of Citroen C4L: fuel consumption fluctuations due to temperature influence, lack of vehicle maintenance over a long period, and insufficient tire pressure. Fuel consumption fluctuations due to temperature influence: Generally, in winter when temperatures are low, fuel consumption tends to increase, almost comparable to fuel consumption when using air conditioning in summer. Lack of vehicle maintenance over a long period: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, causing increased resistance in various moving parts of the engine, which requires more energy to overcome, thus increasing fuel consumption. Insufficient tire pressure: Insufficient tire pressure increases the contact area between the tires and the ground, leading to greater friction, which means increased driving resistance and higher fuel consumption. Methods to reduce fuel consumption: Press the throttle slowly when starting or accelerating, avoiding sudden or deep presses (e.g., flooring the accelerator); increase tire pressure; remove unnecessary items from the car to reduce weight.
