[RafaelMarie]

The hazards of overfilling engine oil include: 1. Causing crankcase explosion; 2. Blue smoke from the engine exhaust pipe; 3. Piston ring sticking and fuel injector clogging; 4. Reduced engine power output; 5. Oil leakage. The functions of engine oil are: assisting in engine lubrication and wear reduction, cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. The method for changing engine oil is: 1. Run the engine to reach operating temperature; 2. Engage the handbrake and lift the vehicle; 3. Unscrew the filter and drain the oil; 4. Apply new oil to the interface gasket of the new filter; 5. Pour 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 recheck the oil level.
