1. Increased Oil Pressure: Excessive oil can lead to higher oil pressure, which can put stress on the engine's seals, gaskets, and bearings. This can cause leaks, damage components, and reduce the engine's overall lifespan.
2. Aerated Oil: Too much oil in the engine can cause air bubbles to form, leading to aeration of the oil. Aerated oil cannot properly lubricate engine components, resulting in increased wear and potential engine damage.
3. Oil Foaming: Overfilling can also cause oil foaming, where air is whipped into the oil, creating a frothy mixture. Foamed oil can lead to reduced lubrication and can cause damage to engine components.
4. Increased Engine Temperature: Excess oil can hinder proper oil circulation and cooling within the engine. This can lead to increased engine temperatures, which can cause accelerated wear and tear on engine components.
5. Engine Failure: In severe cases, overfilling the oil can cause engine failure. If the oil level is high enough, it can reach the crankshaft, causing it to whip through the oil and foam it. This can lead to a loss of oil pressure and lubrication, resulting in catastrophic engine damage.
To prevent these issues, always adhere to the recommended oil quantity specified by the manufacturer and check the oil level regularly using the dipstick provided.
