How many kilometers can 20 liters of oil drive?

[McCooper]

In the city, an average small car can drive approximately 10 to 15 kilometers per liter of oil. The following is relevant information about engine oil: 1. Introduction: Engine oil, also known as engine lubricant, with a density of about 0.91×10³ (kg/m³), serves to lubricate and reduce friction in the engine, assist in cooling, seal to prevent leaks, prevent rust and corrosion, and provide shock absorption. It is hailed as the 'blood' of the car. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil's performance, giving it certain new properties, making them an important part of lubricating oil. 2. Classification: Engine oils on the market can be simply divided into mineral oil and synthetic oil based on their base oil (vegetable oil is not considered due to its scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic.
