What Happens When Too Much Engine Oil is Added?
2 Answers
Adding too much engine oil can lead to the following situations: 1. Intense agitation between engine components, causing excessive engine load and resulting in power loss; 2. Oil splashing onto the cylinder walls and entering the intake system through the crankcase ventilation system, leading to oil burning issues. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Cooling and temperature reduction; 3. Cleaning and purifying; 4. Shock absorption and cushioning; 5. Rust and corrosion prevention. The method for changing engine oil is: 1. Lift the vehicle with a jack, locate the drain plug, and unscrew it to drain the oil; 2. After removing the oil filter, place a container beneath it; 3. Replace with a new oil filter and add new engine oil.
As an automotive repair professional with years of experience, I've encountered numerous cases of engine oil overfill. Excess oil gets whipped into foam by the crankshaft, introducing air bubbles into the lubrication system. This leads to insufficient oil film protection, increased component friction, engine overheating, and potential severe damage. The excessive pressure may also rupture oil seals, manifested by leaks under the engine or abnormal noises during startup. Fuel consumption spikes while efficiency drops, worsening emissions and air pollution. Always verify the dipstick reading stays between min-max marks during routine checks. If overfilled accidentally, promptly remove excess oil using an extraction pump or seek professional assistance. Never neglect scheduled maintenance - prolonged issues like engine overhaul come with exorbitant costs, and vehicle safety should never be compromised.
