Is it okay to add a little gear oil to engine oil?

[LaEvan]

Under normal circumstances, adding a small amount of gear oil to the engine by mistake will not cause major issues. Here are the specific details: Introduction: Since the engine itself requires engine oil, adding a small amount of gear oil will dissolve and dilute it. Gear oil and engine oil share similarities in their operating principles for the engine. Gear oil also has a lubricating effect, but its viscosity is too high, and the oil film is too thick, which may prevent the oil from reaching the precisely fitted components, thereby accelerating engine wear. If you are concerned about potential problems, you can directly drain it and replace it with new engine oil and an oil filter. Due to the differences in usage conditions, composition, and performance between internal combustion engine oil and gear oil, they should not be mixed. Differences: The performance and functions of gear oil and engine oil are entirely different, so they should not be mixed. If the vehicle shows no abnormal noises, immediately drain the engine oil and replace the oil filter. Clean the system with flushing oil. If flushing oil is not available, add engine oil, start the car, let it idle to warm up, then drain the oil again, refill with fresh engine oil, and replace the oil filter again.
