The engine of your car is the heart that keeps it running, and just like the human heart, it needs to be taken care of to function properly. One of the most common issues that car owners face is engine burning oil, which can be a major concern if left unchecked. Engine burning oil, also known as oil consumption, occurs when the engine consumes more oil than usual, leading to a decrease in the oil level in the engine. This can cause serious damage to the engine and other components, leading to costly repairs. In this blog post, we will explore the causes of engine burning oil and what you can do to prevent it.

The Importance of Engine Oil
Engine oil is a vital component of your car’s engine, and it plays a crucial role in keeping it running smoothly. Engine oil lubricates the moving parts of the engine, reduces friction and wear, and helps to remove dirt and debris from the engine. It also helps to cool the engine and prevents corrosion. Without engine oil, the engine would seize up and eventually fail.
Causes of Engine Burning Oil
There are several reasons why your engine may be burning oil. Some of the most common causes include:
Worn Piston Rings
Piston rings are responsible for sealing the combustion chamber and preventing oil from entering the combustion chamber. If the piston rings are worn out, oil can leak into the combustion chamber and burn, causing the engine to consume more oil than usual.
Low Compression
Low compression in the engine can cause oil to enter the combustion chamber and burn. This can be caused by worn piston rings, damaged cylinders, or a blown head gasket.
Oil Leaks
Oil leaks can occur due to worn seals, gaskets, or piston rings. If oil is leaking into the combustion chamber, it can burn and cause the engine to consume more oil than usual.
Clogged PCV Valve
The PCV (Positive Crankcase Ventilation) valve is responsible for removing blow-by gases from the engine. If the PCV valve is clogged, oil can accumulate in the engine and burn, causing the engine to consume more oil than usual.
Dirty Oil
Dirty oil can cause the engine to consume more oil than usual. If the oil is dirty, it can’t lubricate the engine properly, leading to increased oil consumption.
Incorrect Oil Viscosity
Using the wrong oil viscosity can cause the engine to consume more oil than usual. If the oil is too thin, it can’t lubricate the engine properly, leading to increased oil consumption.
Engine Overheating
Engine overheating can cause oil to break down and become less effective, leading to increased oil consumption. (See Also: What Causes a Diesel Engine to Burn Oil? Common Culprits Revealed)
Bad Oil Pump
A bad oil pump can cause the engine to consume more oil than usual. If the oil pump is faulty, it may not be able to circulate oil properly, leading to increased oil consumption.
Bad Oil Filter
A bad oil filter can cause the engine to consume more oil than usual. If the oil filter is clogged, it may not be able to filter out contaminants properly, leading to increased oil consumption.
Bad Spark Plugs
Bad spark plugs can cause the engine to consume more oil than usual. If the spark plugs are worn out, they may not be able to generate the proper spark, leading to increased oil consumption.
What to Do If Your Engine is Burning Oil
If you suspect that your engine is burning oil, there are several things you can do to prevent further damage:
Check the Oil Level
Regularly check the oil level in your engine to ensure that it is at the recommended level. If the oil level is low, you may need to top it off with the recommended type of oil.
Check for Oil Leaks
Check for oil leaks around the engine and transmission. If you find any leaks, you will need to have them repaired as soon as possible.
Replace the PCV Valve
If the PCV valve is clogged, you may need to replace it. This can be done by a professional mechanic or by following the manufacturer’s instructions.
Replace the Oil Filter
If the oil filter is clogged, you may need to replace it. This can be done by a professional mechanic or by following the manufacturer’s instructions. (See Also: What Happens When Engine Oil Is Low? Engine Damage Consequences)

Preventing Engine Burning Oil
There are several things you can do to prevent engine burning oil:
Regular Oil Changes
Regular oil changes are essential to keep your engine running smoothly. Make sure to change your oil every 5,000 to 7,500 miles, depending on the manufacturer’s recommendations.
Use the Right Oil
Use the right type of oil for your engine. Check your owner’s manual to see what type of oil is recommended for your vehicle.
Check the Oil Level Regularly
Regularly check the oil level in your engine to ensure that it is at the recommended level. If the oil level is low, you may need to top it off with the recommended type of oil.
Replace the PCV Valve
Replace the PCV valve every 30,000 to 50,000 miles, depending on the manufacturer’s recommendations.
Replace the Oil Filter
Replace the oil filter every 5,000 to 7,500 miles, depending on the manufacturer’s recommendations.
Replace the Spark Plugs
Replace the spark plugs every 30,000 to 100,000 miles, depending on the manufacturer’s recommendations.
Conclusion
Engine burning oil is a common issue that can cause serious damage to your engine and other components. By understanding the causes of engine burning oil and taking steps to prevent it, you can keep your engine running smoothly and prolong its lifespan. Remember to regularly check the oil level, replace the PCV valve, oil filter, and spark plugs, and use the right type of oil for your engine. By following these tips, you can prevent engine burning oil and keep your car running smoothly for years to come. (See Also: Car Smells Like Oil When Heat Is On? Find The Cause)
