Is a Fuel Consumption of 10L/100km High for a New Car?

This fuel consumption is relatively high. Temperature fluctuations can cause variations in fuel consumption, which is a normal phenomenon. Relevant explanations are as follows: 1. Temperature effects: Generally, in winter when temperatures are low, fuel consumption tends to increase slightly, almost comparable to fuel consumption when using air conditioning in summer. This is because lower temperatures cause the engine to dissipate more heat. If the vehicle hasn't been maintained for a long time, dirty engine oil and air filters can also lead to increased fuel consumption. 2. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the road surface, resulting in greater friction and thus higher driving resistance, which in turn increases fuel consumption.
