- Engine damage: The extra oil can cause the oil to foam, which can lead to a loss of oil pressure. This can damage the engine bearings and other components.
- Oil leaks: The extra oil can leak out of the engine, causing a mess and potentially contaminating the environment.
- Premature wear and tear: The extra oil can cause the oil pump to work harder than necessary, which can lead to premature wear and tear.
- Reduced performance: The extra oil can make the engine run less efficiently, which can lead to reduced performance and fuel economy.
If you have accidentally added 4 extra quarts of oil to your engine, you should drain the excess oil immediately. You can do this by removing the oil drain plug or by using an oil extractor. Once you have drained the excess oil, you should replace the oil filter and add the correct amount of oil to the engine.
