Does the EA111 Engine Burn Oil?

[Louise]

EA111 engine generally does not burn oil. Engine oil burning may be caused by the engine's structural design or external factors. During engine operation, the use of different oil qualities can easily lead to significant carbon buildup in the combustion chamber, which might be one of the reasons for oil burning. Below are relevant details: Main symptoms of oil burning: The primary symptom of engine oil burning is blue smoke from the exhaust pipe. If the engine vibrates at idle or there is a significant loss of engine oil between routine maintenance intervals (without any leakage), the vehicle may be experiencing oil burning. Causes of oil burning: Oil burning occurs when engine oil enters the combustion chamber and burns along with the air-fuel mixture. This is mainly due to damaged piston rings causing cylinder leakage, allowing oil to enter the combustion chamber. It is recommended to perform maintenance as soon as possible. Prolonged oil burning not only leads to significant oil loss but also increases combustion chamber carbon deposits from burned oil residues, negatively affecting engine performance.
