Which way to turn the fuel tank cap to open it?

In most cases, opening the fuel tank cap requires turning it to the left, while closing it requires turning it to the right. Here is some information about the fuel tank cap: 1. The fuel tank cap refers to the container on a car used for storing gasoline. It is square-shaped, made of stainless steel, and has excellent sealing properties. There is only a small circular opening, about the size of a bottle cap, which facilitates storage. It is usually located at the rear of the vehicle. 2. Modern cars typically allow the trunk and fuel tank cap to be remotely controlled from inside the cabin, providing great convenience to the owner. However, when these features malfunction, they can leave the owner helpless and cause significant inconvenience.
I noticed that fuel tank caps are generally unscrewed counterclockwise and tightened clockwise, a design that applies to most vehicles, from German to Japanese cars. The principle is that turning counterclockwise loosens the threads, making it easier to open the cap for refueling; clockwise tightening secures it to prevent loosening while driving. If the cap gets stuck, avoid forcing it—it might be due to dust blockage or a worn seal. Applying a specialized lubricant and handling it gently is recommended. After driving, checking if the cap is fully closed is crucial; otherwise, fuel evaporation wastes money and pollutes the air. If the chain on a new cap wears out, replace it promptly to avoid loss. Developing the habit of turning off the engine before refueling reduces the risk of accidents.
