What to Do If Too Much Engine Oil is Added?
2 Answers
The solution for adding too much engine oil is to drain or extract the excess oil. The effects of adding too much engine oil are: 1. It may cause the crankcase to explode; 2. The engine exhaust pipe may emit blue smoke; 3. Piston rings may stick, and fuel injectors may become clogged; 4. It reduces the engine's output power; 5. Oil leakage may occur. The functions of engine oil are: assisting in engine lubrication and reducing friction, cooling and lowering temperature, sealing to prevent leaks, preventing rust and corrosion, and damping vibrations. 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 oil filter and drain the oil; 4. Apply new oil to the gasket of the new oil 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 recheck the oil level.
I was also confused when I first encountered this situation. The mechanic told me that overfilling engine oil can cause serious problems. Those markings on the dipstick aren't just for show—if it exceeds the upper limit, you need to act fast. When there's too much oil, the crankshaft churns it like a whisk, creating foam that ruins lubrication—precision parts like pistons and bearing shells take the hit directly. The most obvious signs are sluggish performance and terrible fuel economy, with blue smoke from the exhaust indicating oil burning. DIY fixes are straightforward: get a syringe with tubing and extract the excess through the dipstick tube. But if you've tried two or three times with no improvement, head straight to the shop to drain via the oil plug. Pro tip: after draining, always verify the level three times with the dipstick—test once when cold and once when hot for accuracy.
