Symptoms after replacing with counterfeit engine oil include: 1. Excessive engine temperature; 2. Inability to clean the engine; 3. Rapid oil consumption; 4. Increased wear between pistons and cylinders; 5. Spark plug carbon deposits; 6. Loud engine noise; 7. Engine vibration. The method for replacing engine oil is: 1. Lift the vehicle with a jack, locate and loosen the oil drain bolt to drain the oil; 2. Remove the oil filter and place a container underneath it; 3. Install a new oil filter and add new engine oil. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and purifying; 4. Shock absorption and buffering; 5. Rust and corrosion prevention.
Last time I used fake engine oil, my car started acting strangely with sudden loud noises and a buzzing sound. It felt particularly sluggish during acceleration, as if the throttle had no power. Fuel consumption also increased from the previous 8 liters per 100 kilometers to nearly 11 liters. The temperature warning light on the dashboard came on—short trips were okay, but after half an hour, the temperature gauge would skyrocket. After parking, the engine hood was scalding hot, and there was a strange odor. Upon inspection, the engine oil appeared black and murky, unlike the clear appearance of genuine oil. This counterfeit oil has more impurities and poor lubricity, increasing friction between engine components, which can lead to internal wear over time. I need to switch back to genuine oil and clean the oil system immediately; otherwise, delaying it will only result in higher repair costs.
