What is the fuel consumption per 100 kilometers for a 2.4L displacement older car?

[Barry]

A 2.4L displacement car typically consumes around 10.5 liters of fuel per 100 kilometers. The fuel consumption of a car is not only related to the vehicle itself but also depends on the driver's habits and road conditions. The main factors affecting fuel consumption are as follows: 1. Vehicle-related reasons: As an internal control unit in the car, the oxygen sensor primarily monitors the air-fuel ratio of the engine. Once it is damaged, it will cause an imbalance in the air-fuel ratio, leading to a sudden increase in fuel consumption. When the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases during driving. 2. Long overdue replacement of the "three filters": During vehicle use, the three filters (oil filter, air filter, and fuel filter) must be replaced regularly. If they are not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.
