Why try not to refuel on rainy days?

Because gasoline and diesel are flammable and explosive liquids, oil vapor will be generated when filling, and the increase of electric ions in the air may detonate the oil vapor in thunderstorm weather, so it is impossible for general gas stations to refuel in strong thunderstorm weather. In thunderstorm weather, the refueling gun is likely to introduce stray current into the automobile fuel tank, leading to unstable gasoline molecular movement and burying safety hazards such as fire and explosion. The following are the matters needing attention in automobile refueling: 1, the location of the fuel tank cover: the location of the fuel tank cover is basically unknown before refueling, and the fuel tank cover of the vehicle needs to be replaced after being busy for a long time. 2, gasoline label: there are several kinds of gasoline, the proportion of each gasoline is different, resulting in different performance, so be sure to read the gasoline label before refueling. 3. Blending gasoline: Some vehicles have higher requirements for gasoline. In fact, when there is no such gasoline, the short-term impact of blending gasoline is not great, but the knock of low-grade gasoline is high, and other effects are not great.
