How Long Does It Take to Notice Fake Engine Oil?
2 Answers
Generally, symptoms such as increased noise and insufficient power will appear within 10,000 kilometers. Notes on selecting engine oil for new cars: New cars are still in the break-in period, so special attention should be paid to the selection of engine oil. The grade of the oil should not be too low, and the viscosity should not be too high. Notes on not mixing different types of engine oil: Special gasoline engine oil cannot replace diesel engine oil, mainly to avoid accelerating the wear of diesel engines. Single-grade and multi-grade oils should not be mixed. Different brands of the same type of oil can be temporarily mixed, but long-term mixing should be avoided. Notes on frequently checking oil levels: When using engine oil, it is essential to regularly check the quality and quantity of the oil in use. Only when the crankcase has sufficient oil can the engine maintain a normal lubrication state.
Oh, when it comes to how long it takes to detect fake engine oil, I’ve driven an old car for over a decade and have deep personal experience. Generally, after using fake oil, you’ll start noticing abnormalities within about 1,000 to 2,000 kilometers. First, the engine will begin making strange noises—like a "clattering" sound at idle or a "humming" noise during acceleration, which can be quite unsettling. Fuel consumption will also noticeably increase, jumping from, say, 8 liters per 100 kilometers to 12 liters, burning a hole in your pocket. Another red flag is black or blue smoke from the exhaust, indicating severe oil burning. I once used a counterfeit brand, and within three weeks, problems emerged. Luckily, I switched to genuine oil just in time to avoid major damage. Regularly check the oil’s condition by feeling its viscosity with your fingers—fake oil is often thin like water and easy to spot. In short, don’t overlook the small details, or you might end up spending thousands on an engine overhaul.
