Causes of Oil Burning
Oil burning can be caused by a variety of factors, including:
| Causes | Description |
|---|---|
| Worn-out engine components | Over time, engine components such as piston rings, cylinder walls, and valve stem seals can wear out, allowing oil to escape and burn. |
| Oil leaks | Leaks in the engine’s oil system can cause oil to escape and burn. |
| Low oil levels | Driving with low oil levels can cause the engine to burn oil, as the oil is not able to properly lubricate moving parts. |
| Incorrect oil viscosity | Using the wrong type of oil or oil viscosity can cause the engine to burn oil, as the oil is not able to properly lubricate moving parts. |
| Bad spark plugs | Worn-out or fouled spark plugs can cause the engine to run rich, leading to oil burning. |
| Clogged air filter | A clogged air filter can cause the engine to run rich, leading to oil burning. |
Signs and Symptoms of Oil Burning
If your car is burning oil, you may notice the following signs and symptoms:
- Oil leaks or drips under the car
- Excessive oil consumption (more than 1 quart every 1,000 miles)
- Increased oil consumption when the engine is cold
- Blue or white smoke coming from the exhaust pipe
- Oil smell in the car or in the garage
- Decreased fuel efficiency
- Increased engine noise or knocking
What to Do if Your Car Is Burning Oil
If you suspect that your car is burning oil, there are several steps you can take to address the issue:
Check the Oil Level
The first step is to check the oil level in your car’s engine. If the level is low, you may need to add oil to bring it back up to the recommended level.

Check for Leaks
Next, check the engine for any signs of leaks. Look for drops of oil on the ground or on the engine itself. If you find any leaks, you’ll need to address them before they cause further damage.
Check the Air Filter
A clogged air filter can cause the engine to run rich, leading to oil burning. Check the air filter and replace it if it’s dirty or clogged.
Check the Spark Plugs
Worn-out or fouled spark plugs can cause the engine to run rich, leading to oil burning. Check the spark plugs and replace them if they’re worn out or fouled.
Use the Correct Oil Viscosity
Using the wrong type of oil or oil viscosity can cause the engine to burn oil. Check your car’s owner’s manual to see what type of oil and viscosity are recommended for your vehicle.
Consider a Tune-Up
If your car’s engine is burning oil, it may be a sign that it’s due for a tune-up. A tune-up can help to identify and address any issues with the engine’s ignition system, fuel system, or other components. (See Also: How to Change Your Motor Oil? The Ultimate Guide)
