What are the effects of excessive engine oil on the engine?

[DelLaura]

Excessive engine oil can have the following effects on the engine: 1. Increased oil consumption; 2. Reduced engine power; 3. Accelerated carbon deposit formation, damaging certain engine components; 4. Potential oil leakage from the crankshaft oil seal and shortened oil service life. Methods to address overfilled engine oil include: 1. Draining excess oil by removing the oil drain plug; 2. Using an oil pump to extract the excess. The primary functions of engine oil are: 1. To separate and lubricate moving parts, reducing component wear; 2. To carry heat back to the oil pan for dissipation into the air, assisting the radiator in cooling the engine; 3. To circulate and remove carbon deposits, sludge, and metal particles from engine components back to the oil pan, keeping the working surfaces clean.
