The sound of your car’s engine purring smoothly, the feel of the warm sun on your skin as you cruise down the highway, and the satisfaction of knowing you’re getting where you need to go – these are just a few of the joys of car ownership. But, there’s one thing that can quickly turn that joy into frustration: excessive oil consumption. When your car starts burning oil at an alarming rate, it can be a real concern, not just for your wallet, but for the health of your vehicle as well.
Oil consumption is a common issue that can affect any car, regardless of make or model. It’s estimated that over 20% of all cars on the road are experiencing some level of oil consumption, and it’s often a symptom of a larger problem. When your car is burning oil, it’s not just a matter of topping off the tank and calling it a day – it can be a sign of worn engine components, faulty seals, or even a blown head gasket. In this article, we’ll explore the reasons why your car might be burning oil so fast, and what you can do to address the issue.
Common Causes of Oil Consumption
Before we dive into the solutions, it’s essential to understand the common causes of oil consumption. Here are some of the most common reasons why your car might be burning oil:
Worn Engine Components
One of the most common causes of oil consumption is worn engine components. Over time, the moving parts in your engine can wear down, causing the engine to consume more oil than usual. This is especially true for older cars, which may have worn-out piston rings, cylinder walls, or valve stem seals.
Faulty Seals and Gaskets
Another common cause of oil consumption is faulty seals and gaskets. These seals and gaskets are designed to keep the engine’s internal components lubricated and sealed. However, when they become worn or damaged, they can allow oil to leak out of the engine, causing consumption.
Blown Head Gasket
A blown head gasket is a serious problem that can cause oil consumption. When a head gasket fails, it allows coolant and oil to mix, which can cause the engine to consume more oil than usual. This is often accompanied by other symptoms, such as coolant leaks, overheating, and a sweet, pungent smell coming from the engine.
Clogged PCV Valve
The Positive Crankcase Ventilation (PCV) valve is responsible for recirculating the gases that build up in the engine’s crankcase. When the PCV valve becomes clogged, it can cause the engine to consume more oil than usual. This is because the clogged valve prevents the gases from being recirculated, causing them to build up and mix with the oil.
Low Oil Level
A low oil level can also cause oil consumption. When the oil level is too low, it can cause the engine to consume more oil than usual, as the engine is not properly lubricated. This is especially true for cars with oil consumption issues, as the engine may be consuming more oil than usual to compensate for the low level.

Oil Leaks
One of the most obvious symptoms of oil consumption is oil leaks. If you notice oil dripping from the engine or underneath the car, it’s a good idea to check the oil level and look for signs of consumption.
Low Oil Level
A low oil level is another common symptom of oil consumption. If you notice that your oil level is consistently low, it could be a sign that your car is burning oil.
Blue Smoke
Blue smoke coming from the exhaust pipe is another symptom of oil consumption. This is caused by the oil burning off in the engine, which can be a sign of a serious problem.
Increased Oil Consumption
Finally, increased oil consumption is a clear sign that your car is burning oil. If you notice that you’re going through oil faster than usual, it’s a good idea to have it checked out by a mechanic.
How to Fix Oil Consumption
So, how do you fix oil consumption? Here are some steps you can take:
Check the Oil Level
The first step in fixing oil consumption is to check the oil level. Make sure it’s at the recommended level, and top it off if necessary.
Replace the Oil Filter
Next, replace the oil filter. A dirty oil filter can cause the engine to consume more oil than usual, so make sure to replace it regularly.
Check for Leaks
Check the engine for leaks, and make sure to seal any holes or cracks that you find. This will help to prevent oil from leaking out of the engine and reduce consumption. (See Also: Why Does My Car Keep Needing Oil? – Find The Cause)
Replace the PCV Valve
If the PCV valve is clogged, replace it with a new one. This will help to recirculate the gases in the engine and reduce oil consumption.
Check the Head Gasket
Finally, check the head gasket for any signs of damage or wear. If it’s blown, you’ll need to replace it to fix the oil consumption issue.
Prevention is the Best Medicine
Prevention is the best medicine when it comes to oil consumption. Here are some tips to help you prevent oil consumption:
Regular Oil Changes
Regular oil changes are essential for preventing oil consumption. Make sure to change your oil every 5,000 to 7,500 miles, or as recommended by your car’s manufacturer.
Check the Oil Level Regularly
Check the oil level regularly to ensure it’s at the recommended level. This will help to prevent oil consumption and reduce the risk of engine damage.
Replace the Oil Filter Regularly
Replace the oil filter regularly to ensure it’s clean and free of debris. This will help to prevent oil consumption and reduce the risk of engine damage.
Drive Smoothly
Finally, drive smoothly and avoid sudden acceleration or braking. This will help to reduce the stress on the engine and prevent oil consumption.
