The GDI engine is a popular choice among car enthusiasts, known for its reliability and performance. However, one common issue that many GDI engine owners face is oil burning. Oil burning, also known as oil consumption, occurs when the engine consumes more oil than usual, often resulting in a decrease in engine performance and potentially causing damage to the engine over time. In this article, we will explore the causes of GDI engine burning oil and provide a comprehensive guide on how to fix the issue.

Causes of GDI Engine Burning Oil
The GDI engine is prone to oil burning due to its design. The engine uses a direct fuel injection system, which can lead to increased oil consumption. Additionally, the engine’s high compression ratio and turbocharging can also contribute to oil burning. Other factors that may cause GDI engine burning oil include:
Worn Engine Components
Worn engine components, such as piston rings, cylinder walls, and valve stem seals, can allow oil to seep into the combustion chamber, where it is burned along with the fuel. This can lead to increased oil consumption and potentially cause damage to the engine over time.
Low Oil Levels
Low oil levels can cause the engine to burn more oil than usual, as the engine is not properly lubricated. This can be due to a variety of factors, including a faulty oil pressure sensor, a leaky oil drain plug, or a worn oil pump.
Incorrect Oil Viscosity
Using the wrong type of oil or oil viscosity can also contribute to GDI engine burning oil. The engine requires a specific type of oil to operate properly, and using the wrong type can cause the engine to consume more oil than usual.
Turbocharger Issues
Turbocharger issues, such as a faulty turbocharger or a clogged turbocharger, can also cause GDI engine burning oil. The turbocharger is responsible for compressing the air entering the engine, and if it is not functioning properly, it can cause the engine to consume more oil than usual.
Ignition System Issues
Ignition system issues, such as a faulty spark plug or ignition coil, can also cause GDI engine burning oil. The ignition system is responsible for generating the spark that ignites the fuel in the engine, and if it is not functioning properly, it can cause the engine to consume more oil than usual.
Symptoms of GDI Engine Burning Oil
The symptoms of GDI engine burning oil can vary depending on the severity of the issue. Some common symptoms include: (See Also: Can You Smell When Your Car Needs an Oil Change? The Surprising Answer)
Oil Leaks
Oil leaks can be a sign of GDI engine burning oil. If you notice oil leaking from the engine, it may be a sign that the engine is consuming more oil than usual.
Increased Oil Consumption
Increased oil consumption is a common symptom of GDI engine burning oil. If you notice that your engine is consuming more oil than usual, it may be a sign that the engine is burning oil.
Decreased Engine Performance
Decreased engine performance can also be a symptom of GDI engine burning oil. If you notice that your engine is not performing as well as it used to, it may be a sign that the engine is burning oil.
How to Fix GDI Engine Burning Oil
Fixing GDI engine burning oil requires a combination of diagnostic testing and repairs. Here are some steps you can take to fix the issue:
Check the Oil Level
The first step in fixing GDI engine burning oil is to check the oil level. Make sure the oil level is at the recommended level, and if it is low, add the recommended amount of oil.
Check for Oil Leaks
Next, check for oil leaks around the engine. Look for signs of oil leaks, such as oil spots or stains under the engine. If you find an oil leak, you will need to repair it before proceeding.
Check the Turbocharger
Next, check the turbocharger for any issues. If the turbocharger is faulty or clogged, it can cause the engine to consume more oil than usual. You may need to replace the turbocharger or have it cleaned and serviced. (See Also: What Causes Engine Oil To Go Low? – Unveiled)
Check the Ignition System
Next, check the ignition system for any issues. If the ignition system is faulty, it can cause the engine to consume more oil than usual. You may need to replace the spark plug or ignition coil.
Replace the Oil Pump
If the oil pump is faulty, it can cause the engine to consume more oil than usual. You may need to replace the oil pump to fix the issue.
Use the Correct Oil Viscosity
Finally, make sure you are using the correct oil viscosity for your engine. Using the wrong type of oil can cause the engine to consume more oil than usual. Check your owner’s manual to find out what type of oil is recommended for your engine.
Conclusion
GDI engine burning oil is a common issue that can be caused by a variety of factors. By following the steps outlined in this article, you can diagnose and fix the issue. Remember to always check the oil level, check for oil leaks, check the turbocharger, check the ignition system, replace the oil pump, and use the correct oil viscosity to fix GDI engine burning oil.
