What does 'several points of fuel consumption' mean for a car?

[DelGraham]

The term 'several points of oil' refers to the number of liters of gasoline consumed per 100 kilometers. For example, '8 points of oil' means the car consumes 8 liters of gasoline to travel 100 kilometers. The method to calculate a car's fuel consumption is roughly as follows: divide the amount of fuel used by the distance traveled in kilometers and then multiply by 100. For instance: if you use 20 liters of fuel to travel 300 kilometers, then 20 divided by 300 equals 0.066. This means the car's fuel consumption is approximately 6.6 liters per 100 kilometers. Calculating a car's fuel consumption can only give an approximate figure; achieving absolute precision without any error is impossible. This is because many factors affect a car's fuel consumption, such as road conditions, individual driving habits and skills, load conditions, speed, etc. Even for the same car, different drivers will have different fuel consumption rates.
