Can You Still Drive with Overheated Engine Oil?
1 Answers
The normal operating temperature of engine oil is generally between 70-90°C. In cases of overheated engine oil, it is recommended that the vehicle owner should not continue driving. Overheated engine oil will cause a decrease in oil viscosity, leading to increased friction and wear on various components, and shortening the engine's lifespan. Below are the effects of overheated engine oil: 1. Oil burning: Excessive engine temperature causes the oil viscosity to decrease, resulting in oil burning and the inability to form an oil film to protect the friction surfaces of components, accelerating part aging. Reduced oil viscosity also weakens sealing performance. 2. Premature fuel combustion: High engine temperature causes the fuel injected into the cylinders to ignite prematurely, reducing cylinder compression force and lowering power output. Additionally, parts expand due to heat, leading to jamming during operation, significantly reducing bearing performance and efficiency, and causing a series of adverse consequences.
