What Does Excessive Engine Oil Mean?

[VanLayla]

Excessive engine oil refers to a situation where, in low-temperature environments, the oil temperature fails to rise sufficiently, causing the oil-gas separator to malfunction. As a result, the engine has to inject more fuel to maintain RPM, leading to fuel seeping into the engine oil. The consequences of excessive engine oil include: 1. Reduced engine power output: During operation, the crankshaft and connecting rod big ends move rapidly. Excessive oil causes these components to agitate the oil violently, consuming energy and inadvertently reducing the engine's power output while also increasing fuel consumption. 2. Blue smoke from the exhaust pipe: Excessive oil leads to significant splashing by the crankshaft and connecting rod big ends, forcing oil into the combustion chamber where it burns, resulting in blue smoke from the exhaust. 3. Piston ring seizure and fuel injector clogging: Large amounts of oil forced into the combustion chamber burn and form carbon deposits on the piston rings, piston tops, valve seats, and fuel injectors, leading to issues like piston ring seizure and fuel injector clogging.
