Is it serious to run 3000 kilometers with fake engine oil?
3 Answers
Running 3000 kilometers with fake engine oil is not serious. Here is an introduction to engine oil related content: Increased fuel consumption: When adding engine oil, the amount of oil should be between the upper and lower limits of the dipstick. If too much engine oil is added, the volume will expand when the engine temperature rises, causing increased pressure in the oil chamber and greater running resistance, which will lead to reduced vehicle power and increased fuel consumption. Overfilling engine oil: If too much engine oil is added, the crankcase breather pipe may leak oil, and the increased pressure in the crankcase can loosen the oil seals due to oil pressure, leading to oil leaks. Heat dissipation: Overfilling engine oil can affect engine cooling.
Using counterfeit engine oil for 3,000 kilometers is indeed quite dangerous. A friend of mine experienced this firsthand—the engine oil he bought was fake. After driving 3,000 kilometers, the engine noise increased significantly. When he took it to the repair shop, they found excessive sludge buildup, poor lubrication, and accelerated wear on internal components, costing him thousands in repairs. If not detected in time, the entire engine could have been ruined. That’s why I strongly recommend going to a professional shop to replace it with genuine oil as soon as possible. Also, check the dipstick to see if the oil has turned black or has an unusual odor. Always choose reputable sources for maintenance—spending a little extra can prevent major losses.
From a maintenance experience perspective, counterfeit engine oil has unstable quality. If lubrication is insufficient, engine components such as piston rings or crankshafts will wear out faster after 3,000 kilometers, potentially causing abnormal overheating or vibration. Don't risk continuing to use it—get your oil pressure and filter checked immediately. If you notice a drop in power or a sudden increase in fuel consumption, these are warning signs. Regular maintenance with genuine engine oil is the reliable approach; don't cut corners to save money and create hidden dangers.
