What Causes Abnormal Engine Noises When the Engine Oil Burns Out?

[Ria]

There are many reasons for abnormal engine noises when the engine oil burns out, including excessively high oil viscosity, improper timing belt tension, incomplete fuel combustion, exhaust system malfunctions, and cooling system issues. If abnormal engine noises occur, timely inspection and measures should be taken. Below is a detailed explanation of the causes of abnormal engine noises: 1. Unsuitable engine oil: If the oil viscosity is too high, it can lead to insufficient lubrication in the engine, causing friction. It is recommended that car owners choose the appropriate oil for their vehicles during maintenance to avoid this issue. 2. Timing belt noise: Insufficient tension in the timing belt can cause it to stretch excessively under prolonged use, resulting in abnormal noises. This requires adjustment of the timing belt tension at a repair shop or, in severe cases, replacement. 3. Incomplete fuel combustion: Using poor-quality fuel can prevent the engine from operating normally and efficiently. In such cases, it is necessary to refuel with high-quality gasoline.
