Is 20 liters per 100 kilometers considered high fuel consumption?

[EliLynn]

20 liters per 100 kilometers is considered high fuel consumption. Here are some explanations regarding vehicle fuel consumption: 1. Temperature effects causing fuel consumption fluctuations: This is a normal phenomenon. Generally in winter when temperatures are low, fuel consumption increases somewhat, almost comparable to fuel consumption when using air conditioning in summer. This occurs because lower temperatures cause the engine to dissipate more heat. 2. Prolonged lack of vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Contaminated oil provides poor lubrication, causing increased resistance in various moving engine components that require more energy to overcome, resulting in higher fuel consumption. 3. Insufficient tire pressure: Low tire pressure increases the contact area between tires and the road surface, increasing friction and thus driving resistance, which leads to higher fuel consumption.
