What is 93 gasoline?

[TessaFitz]

93 gasoline is a type of fuel with an octane rating of 93, suitable for mid-range vehicles with relatively low compression ratios. The primary criterion for selecting gasoline grades is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles. The most cost-effective and efficient way to reduce fuel consumption is to increase the engine's compression ratio. Below is relevant information about engine oil: 1. Function of engine oil: Engine oil lubricates and reduces friction in the engine, assists in cooling, provides sealing to prevent leaks, prevents rust and corrosion, and offers shock absorption. It is often referred to as the 'blood' of a car. Choosing the right engine oil and changing it regularly can maintain the engine in good condition and extend its lifespan. 2. Choosing engine oil: The selection of engine oil is not about choosing the most expensive one but rather about selecting the most suitable oil based on the characteristics of the car's engine and the driver's habits. It can be categorized based on winter and summer usage. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there's no need to choose an oil with a superior low-temperature viscosity grade.
