Does exceeding the upper limit of the engine oil dipstick have any impact?

[AveryLee]

Exceeding the upper limit of the engine oil dipstick does have an impact, and the effects include: 1. Hindering the operation of the crankshaft; 2. Increasing engine pressure, which affects the engine's power output. The functions of engine oil are: assisting in engine lubrication and reducing friction, cooling and temperature reduction, sealing and leak prevention, rust and corrosion prevention, and shock absorption. The method for changing engine oil is: 1. Run the engine to bring it to operating temperature; 2. Engage the handbrake and lift the vehicle; 3. Unscrew the filter and drain the oil; 4. Apply new oil to the gasket of the new filter; 5. Pour the new oil into the oil pan; 6. Check for leaks under the engine; 7. Lower the vehicle, check the oil dipstick, and start the engine; 8. Turn off the engine and repeat the oil level check.
