Why My Car Consumes More Engine Oil
If you’re noticing that your car is consuming more engine oil than usual, it’s important to take action. Excessive oil consumption can lead to a number of problems, including engine damage. In this article, we’ll discuss some of the most common reasons why cars consume more oil than usual and what you can do to fix the problem.
1. Worn Piston Rings
Piston rings are responsible for sealing the combustion chamber and preventing oil from leaking into the cylinders. Over time, piston rings can wear out and become less effective at sealing the combustion chamber. This can lead to increased oil consumption.
Symptoms of worn piston rings:
- Blue smoke from the exhaust
- Loss of power
- Increased oil consumption
How to fix worn piston rings:
The only way to fix worn piston rings is to replace them. This is a major engine repair that should be performed by a qualified mechanic.
2. Worn Valve Guides
Valve guides are responsible for guiding the valves as they open and close. Over time, valve guides can wear out and become loose. This can allow oil to leak into the combustion chamber, leading to increased oil consumption.
Symptoms of worn valve guides:
- Blue smoke from the exhaust
- Loss of power
- Increased oil consumption
- Ticking noise from the engine
How to fix worn valve guides:
Worn valve guides can be replaced without removing the cylinder head. However, this is still a relatively major repair that should be performed by a qualified mechanic.
3. Leaking Oil Pan
The oil pan is responsible for holding the oil that lubricates the engine. Over time, the oil pan can develop leaks due to rust or damage. This can lead to increased oil consumption.
Symptoms of a leaking oil pan:
- Oil spots under the car
- Low oil level
How to fix a leaking oil pan:
A leaking oil pan can be repaired by replacing the oil pan gasket. This is a relatively minor repair that can be performed by a DIYer with basic mechanical skills.
4. Leaking Oil Filter
The oil filter is responsible for removing contaminants from the oil. Over time, the oil filter can become clogged and restrict oil flow. This can lead to increased oil consumption.
Symptoms of a leaking oil filter:
- Oil spots under the car
- Low oil level
How to fix a leaking oil filter:
A leaking oil filter can be repaired by replacing the oil filter. This is a relatively minor repair that can be performed by a DIYer with basic mechanical skills.
5. Overfilling the Engine with Oil
Overfilling the engine with oil can lead to increased oil consumption. This is because the excess oil can splash around and leak out of the engine. It can also lead to engine damage, so it’s important to avoid overfilling the engine with oil.
Symptoms of overfilling the engine with oil:
- Oil spots under the car
- High oil level on the dipstick
How to fix overfilling the engine with oil:
If you’ve overfilled the engine with oil, you can drain the excess oil by removing the oil drain plug. Be sure to replace the oil filter after you’ve drained the excess oil.
Conclusion
If you’re noticing that your car is consuming more engine oil than usual, it’s important to take action. Excessive oil consumption can lead to a number of problems, including engine damage. By following the tips in this article, you can diagnose and fix the problem and keep your car running smoothly.
