What Are the Reasons for Engine Oil Loss in a Car?
2 Answers
The reasons for engine oil loss in a car: 1. Damage to the engine's turbo system, which can consume a large amount of oil. 2. Failure of the engine's cylinder head gasket. 3. Damage to the engine's piston rings. 4. Impact on the oil pan leading to oil leakage. Oil shortage is a serious issue; if not repaired promptly, it can cause the engine to be scrapped. Below are some related preventive measures: 1. Use high-quality engine oil. Engine oil is highly susceptible to corrosion and aging under prolonged high temperatures, causing the oil film to thin and making it easier to enter the combustion chamber and participate in combustion. Therefore, using high-quality engine oil can significantly delay this phenomenon. 2. Pay attention to the cleanliness of the fuel system. During the combustion process, fuel inevitably produces carbon deposits, which are the root cause of some car problems, such as aging of valve seals and increased piston-cylinder wall clearance. These issues are directly or indirectly related to carbon deposits. Therefore, maintaining the cleanliness of the fuel system is very helpful in preventing oil burning.
I've repaired countless cars, and common reasons for low engine oil include engine oil burning, where oil is burned off due to worn piston rings or valve seals, possibly causing blue smoke from the exhaust pipe. Oil leaks are also frequent, such as from aging or cracked oil pan gaskets, leading to slow seepage, visible as oil stains on the ground when parked. Or, there might be leaks from poorly sealed oil filters. Improper maintenance, like overfilling or underfilling oil, can trigger warning lights. High engine temperatures can cause some oil to evaporate, which is normal, but excessive consumption needs investigation. It's advisable to regularly check oil levels with the dipstick, especially before long trips, and changing the oil every 5,000 kilometers can reduce risks.
