It may be due to various reasons such as obstructed fuel flow, a dead battery, an empty fuel tank, incorrect gear position, etc. These issues can usually be resolved by oneself. However, other causes like improper fuel quality or excessive carbon buildup require professional attention at an auto repair shop. Below is a brief introduction about engine oil: 1. Function: Engine oil is crucial for the engine. It not only lubricates but also cleans, seals, buffers, prevents rust, and dissipates heat. During engine operation, the oil forms a protective film on the surfaces of various components, preventing direct contact and friction. 2. Precautions: Over time, engine oil loses its effectiveness, so it must be replaced regularly. Failure to do so can accelerate engine wear.
