What Causes the Engine Oil Cap to Be Too Tight to Unscrew?
1 Answers
If you have just driven the car, you can wait for the engine temperature to drop before attempting to open it. The oil cap may be difficult to unscrew due to excessive suction. Below is some information about engine oil: 1. Function: Engine oil is crucial for the engine. It not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, the oil forms a thin film on the surfaces of various components, preventing direct contact and friction between them. 2. Precautions: Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Failure to change the oil for extended periods can accelerate engine wear.
