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

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.
I've driven many older 2.4L displacement cars myself, such as 1990s Toyota Camry or Honda Accord models, with fuel consumption typically ranging from 10 to 14 liters per 100 kilometers. Vehicle condition makes a huge difference: with well-maintained engines, newly replaced spark plugs, and clean air filters, highway driving can be kept around 11L/100km. However, older cars often have wear issues—when piston rings leak or fuel injectors clog, city driving consumption can spike above 15L/100km. To save money, I insist on regular maintenance: changing engine oil and decarbonizing every 5,000 kilometers, maintaining proper tire pressure, and avoiding aggressive acceleration and braking while driving. Though fuel consumption is 2-3 liters higher than new cars, good habits help keep it within budget. The key is choosing the right route—smooth driving is the most fuel-efficient.
I just bought an older Ford with a 2.4L engine, which feels quite vintage to drive, but I calculated its average fuel consumption to be around 13L per 100km. As a young person, I'm more concerned about saving money: an aging engine might consume more fuel. I've been tracking the fuel gauge weekly and noticed that maintaining a steady 80km/h on the highway reduces consumption to 11L, but short city trips in traffic can push it up to 15L. I started paying attention to maintenance details, like switching to synthetic oil and cleaning the throttle body, which noticeably reduced fuel consumption. Talking with friends, they all said that with proper maintenance, older cars can stabilize fuel consumption below 12L. Overall, it's not too bad—the car was cheap, parts are plentiful, and with proper upkeep, it's still a cost-effective daily driver.
