Causes:
- Worn piston rings: Piston rings are designed to seal the combustion chamber and prevent excessive oil consumption. If the piston rings become worn, oil can seep into the combustion chamber and be burned, leading to excessive oil consumption.
- Incorrect oil viscosity: Using oil that is too thin can lead to increased oil consumption. The recommended oil viscosity for your car is 5W-30.
- Leaking valve cover gasket: If the valve cover gasket is leaking, oil can drip onto the engine block and burn off, leading to excessive oil consumption.
- Clogged PCV valve: The PCV valve helps to control crankcase pressure and recirculate oil vapors back into the engine. If the PCV valve becomes clogged, it can lead to increased oil consumption.
- High engine temperatures: If the engine is running too hot, it can cause the oil to break down and evaporate more quickly, leading to excessive oil consumption.
- Oil filter: Using a poor-quality oil filter can lead to increased oil consumption. Make sure to use a high-quality oil filter that is designed for your car.
- Head gasket: In extremely rare instances, a head gasket leak can cause oil consumption.
