Reasons for Increased Engine Oil Level

[DiReagan]

Reasons for increased engine oil level are as follows: 1. Gasoline or water entering the engine oil. During vehicle operation, if the piston or cylinder sealing is poor, allowing mixed gases to enter the engine crankcase, liquefaction occurs when temperatures drop, causing the engine oil level to rise and resulting in increased oil volume. 2. Engine component mechanisms. Increased engine oil volume is also related to engine components. For example, insufficient cylinder pressure indicates reduced cylinder sealing, decreased engine power, and difficulty starting. Another scenario is faulty fuel injectors causing dripping or excessive fuel injection. Both situations require inspection by a technician to identify the cause and perform repairs. 3. Temperature. Increased engine oil volume is somewhat related to temperature. In engine design, a richer air-fuel mixture is required for cold starts, necessitating more fuel injection. In most vehicle models, increased oil volume may result from excessive fuel injection.
