Does refueling on rainy days have any impact?
2 Answers
Refueling is not recommended on rainy days for the following reasons: 1. During thunderstorms, the fuel nozzle may introduce stray currents into the vehicle's fuel tank, which can increase the movement of unstable gasoline molecules, posing potential hazards such as fire or explosion. 2. The concentration of fuel vapor at gas stations is significantly higher than in other areas. Refueling during thunderstorms can easily lead to the fuel vapor being struck by lightning, causing explosions in both the vehicle and the fuel tank. Here is additional information: 1. There are many types of gasoline, each with different component ratios, leading to variations in performance. Therefore, it is essential to check the gasoline grade before refueling. 2. Some vehicles have higher requirements for gasoline. If the required gasoline is not available, mixing different grades for a short period has minimal impact, except that lower-grade gasoline may have higher knock characteristics, with little other effect.
I remember the summer two years ago when it rained particularly heavily. I was in a hurry to refuel, but after starting the engine, it kept shaking and lacked power when driving. Later, at the repair shop, the mechanic said rainwater might have seeped into the fuel tank through the fuel filler opening, diluting the gasoline and causing incomplete combustion. Since then, I try to refuel on sunny days to avoid such trouble. On rainy days, there are many puddles on the road, making it easier to skid while driving to the gas station, which increases the risk. When refueling, always make sure to close the fuel cap properly to prevent rainwater from getting in, saving time and money on repairs. Generally, it’s safer to wait until the rain stops before refueling.
