What are the effects of overfilling engine oil in a car?
1 Answers
The effects of overfilling engine oil in a car: 1. Increased fuel consumption: When the engine cylinder contains too much oil, it creates unnecessary resistance to the crankshaft's rotation, affecting power output and increasing fuel consumption; 2. Reduced power: Excessive oil entering the combustion chamber leads to more carbon deposits, increasing piston movement resistance and reducing engine power; 3. Environmental non-compliance: Overfilling oil worsens exhaust emissions, severely affecting the lifespan of the catalytic converter, and may even directly damage it; 4. Oil leakage: Reduces the lifespan of oil seals and may cause engine oil leaks.
