The cost of fixing a car that burns oil varies depending on the cause and severity of the issue. Here's a rough breakdown:
Oil burning can lead to several types of engine damage if not addressed promptly. These include:
Piston rings play a vital role in sealing the combustion chamber and preventing oil from entering it. When these rings wear out, oil can seep into the combustion chamber and burn along with the fuel.
Using oil that is too thin or not recommended for your car can result in higher oil consumption and burning.
The Positive Crankcase Ventilation (PCV) valve helps regulate pressure in the engine. A faulty PCV valve can cause oil to be drawn into the intake manifold and burned in the combustion chamber.
Internal oil burning occurs when oil enters the combustion chamber and burns along with the fuel. This is usually caused by worn piston rings, valve seals, or a malfunctioning PCV valve.
Blue smoke is a clear sign of oil burning. Have your car inspected by a mechanic as soon as possible.
