What does 'how many oil' mean for a car?

'How many oil' for a car refers to its fuel consumption per 100 kilometers, indicating how many liters of fuel the vehicle consumes to travel 100 kilometers. This is a theoretical indicator of the vehicle. The 100km fuel consumption is measured by manufacturers under controlled conditions using a dynamometer installed on the vehicle chassis, converting the values into speed parameters, then calculating the theoretical experimental 100km fuel consumption data for the model at specified speeds. The calculation formula for 100km fuel consumption is based on the fuel refill amount and the distance traveled with that amount. For example, if a car uses 20 liters of fuel to travel 400 kilometers, the calculation method is: 20 divided by 400 equals 0.05 liters, resulting in a fuel consumption of 0.05 liters per kilometer, which converts to 5 liters per 100 kilometers, commonly referred to as '5 oil' for the car.
When chatting with friends about cars, we often hear the term ‘how many liters of oil does the car use’, which refers to fuel consumption—how many liters of fuel the car burns per 100 kilometers. My car typically consumes around 8 liters, meaning it uses 8 liters of fuel per 100 kilometers. This number can vary depending on driving habits; if you press the accelerator more aggressively, fuel consumption might jump to over 10 liters. In city traffic jams, fuel consumption is higher, while on highways, it’s lower. To save fuel, I prefer maintaining a steady speed, as 60 to 80 kilometers per hour is the most economical. Different car models have varying fuel consumption—small cars might use 6 to 7 liters, while SUVs generally consume 9 to 12 liters. Before buying a car, it’s best to check the official data and predict actual expenses based on your daily commute conditions. Regular maintenance can reduce fuel consumption, such as replacing spark plugs and engine oil, keeping tire pressure optimal, and avoiding engine overload. These tips come from my personal experience to help you save money.
