Why Do Audi Cars Burn Engine Oil?

[DiXavier]

Audi cars burn engine oil for the following reasons: 1. The engines in Audi cars are high-compression engines. The advantages of high-compression engines are high power, large torque, and low fuel consumption, which leads to oil burning. 2. The engine compression ratio is higher. Once the compression ratio increases, the temperature inside the engine cylinders rises. Higher temperatures can cause engine oil to be consumed. 3. The physical structure of direct-injection engines in cars differs from traditional port fuel injection engines. Fuel is directly injected into the cylinders through high-pressure atomization via injectors inside the cylinders. This process is different from port fuel injection engines, so during atomization, some fuel may directly spray onto the cylinder walls, diluting the engine oil and burning it off, which also results in minimal oil consumption.
