How Much Fuel Should a Sedan Refuel?
2 Answers
There are two scenarios for refueling a sedan: 1. Short-distance driving: When driving short distances, the fuel should be filled up to 80% of the tank capacity. 2. Long-distance driving: For long trips, the fuel should be filled up to 90% of the tank capacity to avoid increasing the vehicle's load and causing unnecessary fuel consumption. Additional information: Refueling should be done when the fuel level drops to 1/4 of the tank capacity. Waiting until the tank is nearly empty can lead to the accumulation of impurities at the bottom of the tank, which may be drawn into the fuel system and cause poor fuel delivery. Moreover, an almost empty tank can trap air, which, due to large day-night temperature variations, can form condensation and mix with the fuel, leading to poor combustion.
I've always been driving a sedan and filling up the fuel tank until the automatic nozzle stops. The reason is simple: overfilling can cause gasoline to evaporate into the carbon canister system, which may damage components over time and increase maintenance costs. I remember once trying to save a little by forcing a full tank, only to end up with a fuel tank leak that cost me 500 yuan to fix. Now, I usually fill up to about three-quarters full, which reduces the vehicle's weight and saves a bit on fuel costs. Also, don't refuel too frequently—every trip to the gas station wastes fuel unnecessarily. I average about one refill per week, which is just enough for my daily commute. Adjust based on driving habits: fill up before long trips, keep half a tank for short distances, and avoid waiting until the fuel light comes on to prevent overheating and damage to the fuel pump. The key is to develop consistent habits that protect the car and save both hassle and money.
