How do you fix a car that burns oil?
Oil burning is a common issue that many car owners face, and it can lead to serious engine problems if not addressed promptly. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen this issue countless times and are here to guide you through the process of diagnosing and fixing it. Whether your car is emitting blue smoke or you’re noticing a drop in oil levels, this guide will help you understand the causes and solutions for oil burning in vehicles.
What Causes a Car to Burn Oil?
Before diving into the fixes, it’s important to understand why your car might be burning oil. Here are the most common reasons:
- Worn Piston Rings: Piston rings seal the combustion chamber, preventing oil from entering. When they wear out, oil can seep into the chamber and burn.
- Valve Seal Issues: Valve seals prevent oil from leaking into the engine’s cylinders. Damaged seals can cause oil to burn during combustion.
- PCV Valve Malfunction: A faulty Positive Crankcase Ventilation (PCV) valve can lead to excessive oil consumption and burning.
- Engine Wear: High mileage or poor maintenance can cause general engine wear, leading to oil burning.
Steps to Fix a Car That Burns Oil
Fixing a car that burns oil depends on the root cause of the problem. Here’s a step-by-step guide to address the issue:
- Step 1: Check the Oil Level Regularly
Monitor your oil levels frequently. If you notice a significant drop, it’s a sign of oil burning. Top off the oil as needed to prevent engine damage while diagnosing the issue.
- Step 2: Inspect for Leaks
Look for visible oil leaks under your car or around the engine. While leaks don’t directly cause oil burning, they can contribute to oil loss.
- Step 3: Replace the PCV Valve
A clogged or malfunctioning PCV valve is a common and inexpensive fix for oil burning. Replace it and see if the issue improves.
- Step 4: Conduct a Compression Test
If the problem persists, perform a compression test to check for worn piston rings or cylinder damage. This step may require professional assistance.
- Step 5: Replace Worn Piston Rings or Valve Seals
If the compression test reveals issues, you’ll need to replace the worn components. This is a more complex repair that typically requires a mechanic’s expertise.
- Step 6: Use High-Mileage Oil
Switching to high-mileage oil can help reduce oil burning in older engines by conditioning seals and reducing leaks.
When to Seek Professional Help
While some fixes, like replacing the PCV valve or switching to high-mileage oil, can be done at home, more complex repairs such as replacing piston rings or valve seals require professional expertise. At Kevin's Autos, we specialize in diagnosing and repairing oil-burning issues, ensuring your car runs smoothly and efficiently.

How do you fix an oil burn?
First and second-degree burns (including cooking oil burns) can be treated with aloe vera, burn creams, or antibiotic ointment after running cool water over the area to reduce its temperature. These treatments can provide temporary relief to keep the pain at bay.
Does burning oil mean I need a new engine?
It is important to know that engines are designed in a way that they burn oil as a part of their regular operations. This means that not all excessive consumption of engine oil is an indicator of a problem. Engine manufacturers always indicate what the normal amount of oil consumption is under defined conditions.
Can you flush an engine?
A good engine flush can help loosen deposits and dissolve sludge, helping return your engine to like-new condition. However, in old engines with high miles, sludge may be the only barrier keeping oil from seeping through worn or cracked seals. Removing the sludge exposes the seals for what they really are – junk.
How much does it cost to fix a burning oil car?
The cost to fix an oil burning issue can range from $10 for a PCV valve replacement to well over $1,000 for repairs like valve seals or piston rings.
Why is my car losing oil but no leak?
If there are no visible external leaks, you are most likely burning oil in the combustion chamber. There are many points of failure that can cause this.
