The Role of Piston Rings in Oil Consumption

When it comes to oil consumption in cars, a common culprit is worn or damaged piston rings. The piston rings are essential components in the engine that help keep the oil where it belongs – in the oil pan. However, over time, these rings can wear down or become damaged, allowing oil to bypass them and enter the combustion chamber.

When oil enters the combustion chamber, it burns along with the fuel and air mixture, resulting in a blue-gray smoke coming out of the exhaust pipe. This smoke is a tell-tale sign of oil burning, but it may not always be visible or noticeable, making it difficult to diagnose the problem.

The tricky thing about piston rings is that they can allow oil to bypass them without causing any visible leaks. This means that your car can be burning oil without any noticeable puddles under the car or on the ground. Instead, the oil is burned off in the engine, which can lead to decreased engine performance and increased emissions.
