How Long Will It Take for Problems to Appear After Using Fake Engine Oil?

Using fake engine oil may not show immediate effects, but problems and malfunctions are likely to occur after about six months or longer. Below are some related details about engine oil: 1. Identifying Genuine vs. Fake: (1) Packaging: Genuine engine oil packaging is very neat, without rough edges, and the box color is bright. In contrast, fake oil packaging is rough and dull in color. Additionally, many genuine engine oil packages have special manufacturer marks, so be sure to inspect carefully when purchasing. (2) Appearance: Genuine oil is transparent in color, free of impurities and sediment. Fake oil usually has a darker sheen and may contain impurities or sediment. 2. Precautions: Low-quality oil can cause the engine to overheat. Engine oil has a relatively low specific heat capacity and does not inherently cool the engine. However, during engine operation, the oil absorbs heat generated by fuel combustion and transfers it back to the oil tank, where it dissipates into the air, aiding the radiator in cooling the engine. Poor-quality oil struggles to transfer heat effectively, making the engine prone to overheating and reducing its lifespan.
I've seen many cases of fake engine oil in the factory before, with problems appearing as quickly as 2,000 kilometers. Turbocharged cars that frequently drive on highways show particularly obvious symptoms—first, the engine noise increases like a tractor, then the oil warning light flashes more frequently than a disco light. Just two weeks ago, we had to lift an engine where the owner bought so-called 'genuine oil' cheaply online, resulting in sludge completely blocking the oil passages. The key issue is that fake engine oil has virtually zero cleaning capability; when piston rings get stuck due to carbon buildup, burning oil becomes as easy as drinking water. My advice is to stop the car immediately if anything seems off. If the drained oil appears milky or contains metal shavings, the engine is 90% already internally damaged.
