What is the annual difference between 7L and 10L fuel consumption?

The annual difference between 7L and 10L fuel consumption is 20,000 kilometers. There are 3 methods to reduce vehicle fuel consumption: 1) Minimize vehicle weight by keeping the interior tidy and avoiding unnecessary items - each additional 1kg increases fuel consumption by 1%; 2) Avoid excessive modifications - adding spoilers, protective covers, or wings may disrupt the original aerodynamic design, increasing wind resistance and fuel consumption, while lighting modifications increase electrical load and unnecessary fuel usage; 3) Develop good driving habits - avoid sudden acceleration, high-speed driving in low gear, prolonged idling, frequent lane changes or braking, and aim for smooth starts, constant-speed driving, and reduced braking.
I've driven quite a few cars and know there's a significant difference between 7L and 10L fuel consumption. Assuming an annual mileage of 20,000 kilometers, a car with 7L/100km fuel consumption burns 600L less fuel than one with 10L/100km. At current fuel prices of about 8 yuan per liter, that's a yearly saving of 4,800 yuan. This amount could cover several months of insurance or buy some premium tires. For those who drive longer distances, the savings are even greater – frequent long-distance drivers could save enough to buy a new smartphone. I've also noticed that developing good driving habits like minimizing braking and maintaining steady speeds can reduce fuel consumption, though this requires long-term attention.
As someone who often works on their own car, let me calculate this. The difference in fuel consumption is 3 liters per 100 kilometers. If you drive 20,000 kilometers a year, the car with higher fuel consumption will cost an extra 4,800 yuan in fuel. These are just basic figures; the actual difference depends on fuel price fluctuations. For example, last year when fuel prices rose, the difference was even greater. Also, don't overlook the condition of the car. A dirty fuel filter or low tire pressure can increase fuel consumption. Personally, I recommend regular maintenance, checking things like spark plugs, to avoid unnecessary increases in fuel consumption. Driving slower in daily use can also save some fuel.
