How Long Does It Take for Symptoms of Fake Engine Oil to Appear?
1 Answers
Half a year. If a car uses fake engine oil, there may be no noticeable symptoms in the short term. However, after about six months or more, problems and malfunctions may start to appear. How to Distinguish Between Real and Fake Engine Oil: Check the Packaging: Genuine engine oil packaging is very neat, with no rough edges, and the box color is bright. In contrast, fake engine oil packaging tends to be rough and dull in color. Additionally, many genuine engine oil packages have special marks from the manufacturer, so it's important to inspect them carefully when purchasing. Check the Color and Clarity: Real engine oil is transparent in color, free of impurities and sediment. Fake engine oil usually has a darker sheen and may contain impurities or sediment. Precautions: Low-quality engine oil can cause the engine to overheat. Engine oil has a relatively low specific heat capacity and, being inside the engine, does not inherently have a cooling function. However, during engine operation, the oil helps transfer heat back to the oil tank, which then dissipates into the air, assisting the radiator in cooling the engine. Poor-quality engine oil struggles to transfer heat effectively, making the engine prone to overheating and reducing its lifespan.
