What are the different grades of gasoline?

Gasoline grades include 89, 92, 90, 93, 95, etc. Appearance of gasoline: Gasoline is a volatile, flammable hydrocarbon mixture obtained from petroleum distillation and cracking. It is a transparent liquid, flammable, with a distillation range of 30°C to 220°C. Its main components are C5-C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. It has a high octane number and can be used as automobile fuel. Applications of gasoline: Gasoline is primarily used as a power fuel for transportation. In industries such as rubber, paint, dye, printing, pharmaceuticals, and adhesives, gasoline is used as a solvent. It is also employed as a degreasing agent for cleaning parts and clothing, as well as for pre-treatment of electroplated products.
As an ordinary person who drives frequently, I've noticed that gasoline mainly comes in common grades like 87, 89, and 93, which represent the octane rating—the higher the octane, the better the knock resistance. For regular family cars like SUVs or sedans, 87 octane is usually sufficient because it's affordable and hassle-free; while high-performance cars or sports cars may require 93 octane to prevent engine knocking. When fueling up, I always check the owner's manual first to confirm the recommended grade—using the wrong fuel can lead to increased carbon buildup or higher fuel consumption, and even damage the engine over time. Some models require higher octane under extreme driving conditions, so don't blindly opt for the most expensive option; what suits your car is key. Additionally, gas station labels are quite clear: 87 is often labeled as 'regular,' 89 as 'plus,' and 93 as 'premium.' Developing this habit can help avoid misfueling.
