Is a Fuel Consumption of 17 L/100km Normal for a New Car?

[LaCamila]

New car fuel consumption of 17 L/100km is not normal. The reasons for high fuel consumption are as follows: Temperature impact: Generally, in winter when temperatures are low, fuel consumption increases slightly, almost comparable to fuel consumption when using air conditioning in summer. Vehicle overdue for maintenance: 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, requiring more energy to overcome the resistance, thus increasing fuel consumption. Spark plugs need replacement: Although spark plugs may still function after their lifespan, insufficient ignition energy can cause delayed ignition, missing the optimal ignition timing. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the ground, increasing friction, which means greater driving resistance and higher fuel consumption.
