What does 'how many oils does a car use' mean?

"How many oils does a car use" refers to the fuel consumption per 100 kilometers, which means the amount of fuel (in liters) required for a car to travel 100 kilometers. Below is some information about car fuel consumption: 1. Calculation method: (Amount spent on fuel ÷ Fuel price) ÷ Kilometers driven × 100 = Fuel consumption (liters). The number of liters of fuel consumed for a car to travel 100 kilometers is referred to as 'how many oils'. For example: If a car consumes a total of 19 liters of fuel to travel 200 kilometers, it can be said that the car's fuel consumption per 100 kilometers is 9.5 liters. 2. Practical significance: Fuel consumption per 100 kilometers refers to the fuel consumption of a vehicle traveling a certain speed on the road for 100 kilometers. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then the theoretical experimental fuel consumption data per 100 kilometers of the vehicle model is calculated by driving at a specified speed.
When we talk about a car's 'fuel consumption in liters', it refers to how many liters of gasoline the car burns per 100 kilometers. For example, my car consumes about 9 liters per 100 km in city driving, meaning it burns 9 liters of fuel for every 100 kilometers traveled. Actually, this number depends on how you drive. In stop-and-go city traffic, where the engine often operates inefficiently, fuel consumption can easily exceed 10 liters per 100 km. On the highway at a steady speed, it might drop to around 7 liters. Additionally, underinflated tires increase rolling resistance, and a fully loaded trunk also consumes more fuel. So, to save on fuel costs, it's important to develop good driving habits—avoid sudden acceleration and hard braking. The official fuel consumption figures listed on the yellow sticker of new cars are measured under laboratory conditions, and real-world driving will typically be higher, so keep that in mind when buying a car.
