What Should Beginners Pay Attention to When Refueling for the First Time?

When refueling, note that different grades of gasoline cannot be mixed; smoking or making phone calls is prohibited at gas stations; and do not wait until the fuel tank is nearly empty before refueling. Different grades of gasoline cannot be mixed: Mixing different grades of gasoline can easily cause engine knocking, leading to insufficient power and affecting the lifespan of the spark plugs. If your car requires 95# gasoline, do not use 92# unless absolutely necessary. Never assume that using a higher-grade gasoline will improve performance or benefit your car! The appropriate gasoline grade for each vehicle model is determined through countless tests by the manufacturer. Using an incompatible gasoline may prevent the engine from performing at its best. No smoking or phone calls at gas stations: Since gasoline is highly flammable and explosive, never smoke at a gas station. Additionally, the radio frequency generated during phone calls can cause friction with the gas station's computer equipment, potentially igniting vaporized gasoline in the air and triggering an explosion. Waiting until the fuel tank is nearly empty to refuel: This practice severely damages the fuel pump. Continuous operation of the pump generates high temperatures, which are normally cooled by sufficient fuel. However, when the gasoline is nearly depleted, the pump's temperature remains high, negatively impacting its lifespan. Therefore, it is recommended that drivers regularly check the fuel gauge to avoid running too low. Never wait for the fuel warning light to come on before refueling, as the repair costs for components like the fuel pump and oxygen sensor can be quite expensive.
