Does the number 92 at the gas station indicate diesel or gasoline?
2 Answers
At gas stations, the number 92 is clearly marked, and there are two fueling nozzles on the same station dispenser, with gasoline and diesel available at the same station. Here are some precautions for refueling your car: 1. Refuel promptly: The fuel pump generates heat during operation. If the fuel level is insufficient, the pump cannot dissipate heat in time, accelerating its aging. Therefore, it's best to refuel when the tank is down to a quarter full. 2. Fuel quality: When refueling, choose gas stations with better fuel quality. It is recommended to go to state-owned gas stations, as some private ones might use inferior fuel for profit. 3. Octane rating: Always pay attention to the octane rating when refueling. The recommended fuel grade for your car is usually indicated on the fuel tank cap. A car designed for 95 octane can run on 92 octane gasoline, but prolonged use may affect the vehicle. 4. Fuel quantity: Avoid overfilling the tank to reduce trips to the gas station. Generally, filling until the first click of the pump is sufficient, which means the fuel level is about 80-90% full. This leaves enough space in the tank to accommodate gases produced by fuel evaporation.
When I see the 92 sign at the gas station, I immediately think of gasoline, usually labeled as 92-octane gasoline. It's not diesel; diesel is typically marked separately as 'Diesel' or '0# Diesel' at gas stations, without a numerical grading system. The octane rating of 92 represents the gasoline's anti-knock performance; the higher the number, the better the gasoline quality. Having driven for many years, I commonly see gasoline grades including 92, 95, and 98, suitable for different vehicle models; mistakenly adding diesel to a gasoline car can cause engine carbon buildup or stalling, requiring immediate repair. When refueling, it's advisable to first check the vehicle's manual for the recommended fuel type; if unsure, ask the staff. Develop the habit: carefully check the pump nozzle labels; the difference between gasoline and diesel is obvious, and safe operation can extend engine life.
