What types of gasoline are there besides ethanol gasoline?
2 Answers
In addition to ethanol gasoline, there are also leaded gasoline and unleaded gasoline. Currently, gas stations mainly sell 90, 93, 95, 97, and 98 octane gasoline. Here is some additional information: 1. Function: Gasoline burns inside the car, converting thermal energy into kinetic energy for the car's movement. Gasoline is crucial for car travel, enabling the car to run more efficiently. 2. Gasoline selection: It must be chosen based on the car's engine compression ratio. Different compression ratios require different gasoline grades. Selecting the appropriate gasoline ensures optimal utilization and prevents damage to the car's engine. Ethanol gasoline is blended from 90% regular gasoline and 10% ethanol. It can effectively improve fuel performance and quality while reducing pollutant emissions.
As a seasoned driver with over a decade of experience, I often encounter various choices when refueling. Besides ethanol gasoline, the common options include regular unleaded gasoline, such as 92 or 93 octane, which is more affordable and suitable for most household vehicles. There's also high-octane gasoline, like 95 or 97 octane, which offers better combustion efficiency and stronger engine performance, especially useful during high-speed driving or uphill climbs. Additionally, some gas stations offer biofuel gasoline, such as B10 gasoline blended with butanol, which is environmentally friendly but may result in higher fuel consumption. Personally, I prefer 93 octane as it's sufficient for city commuting and offers good value for money. Before choosing gasoline, it's essential to check the vehicle's manual to avoid engine damage, and pay attention to fuel price fluctuations as types may vary by region. In short, select based on your car's condition and budget, and don't just focus on ethanol options.
