Due to differences in road conditions, temperature, vehicle condition, driving conditions, and many other factors, the fuel consumption per 100 kilometers varies for different vehicles. Even for the same car, if driven by different drivers, the fuel consumption will differ. The factors affecting fuel consumption are as follows: High viscosity of lubricating oil: The viscosity of lubricating oil used varies depending on the season, vehicle model, and vehicle condition. It is essential to choose the right lubricating oil for your car based on different situations. Excessive engine carbon deposits: Carbon deposits are one of the main reasons for a sharp increase in engine fuel consumption. If the car's fuel consumption is too high after driving for a period, it is mostly related to excessive carbon deposits. At this time, you can choose a high-quality fuel cleaner to promote the combustion of gum substances in gasoline and harmful substances such as engine carbon deposits, thereby effectively removing carbon deposits and protecting the cleanliness of the fuel system.

I often drive various cars, and the fuel consumption per 100 kilometers can vary greatly depending on the model and road conditions. Generally, family sedans like the Toyota Corolla or Volkswagen Lavida consume around 6-9 liters per 100 kilometers, rising to 9-11 liters in city driving, but can be as low as 5-7 liters on smooth highways. SUVs such as the Haval H6 or Honda CR-V tend to have higher fuel consumption, commonly ranging from 8-12 liters. Older cars or those not well-maintained may consume more fuel, for example, low tire pressure or engine carbon deposits can increase consumption by 1-2 liters. When I drive on highways, I prefer gentle acceleration, keeping fuel consumption stable at around 7 liters. It's advisable to check the official fuel consumption data per 100 kilometers published by the Ministry of Industry and Information Technology when buying a new car. It's normal for actual driving consumption to be slightly higher, but regular maintenance can help optimize it.

I prioritize saving money and being eco-friendly. Fuel consumption can range from 5 to 15 liters per 100 kilometers, largely depending on driving habits and vehicle condition. Aggressive driving with sudden acceleration and hard braking can increase fuel consumption by up to 20%, with urban traffic jams pushing it over 12 liters. Conversely, maintaining a steady speed on highways or using cruise control can reduce consumption to 4-6 liters for small-displacement vehicles. Vehicle type plays a significant role: hybrids like the Toyota Prius average 4-5 liters, compact gasoline cars like the Nissan Sylphy 6-8 liters, while larger vehicles like pickup trucks or SUVs consume 10-15 liters. Regular checks on tires and air filters can help save fuel. Using fuel-tracking apps to record actual consumption is more practical than relying on official figures—saving fuel means saving money.

I measure fuel consumption myself with a simple method: fill up the tank and reset the odometer, then check the distance traveled and fuel refilled when it's time to refuel, calculating liters per 100 kilometers. Generally, small cars consume 6-10 liters in the city and 5-8 liters on highways. Under normal conditions, SUVs may consume 8-12 liters. A sudden increase in fuel consumption could be caused by low tire pressure, aged engine oil, or engine issues. I regularly clean carbon deposits, keeping fuel consumption around 7 liters. This DIY check is cost-effective and easy, and I recommend car owners do it monthly to monitor their vehicle's condition.
