In this article, we’ll explore the causes, signs, and prevention methods of car smoking after an oil change.
As car owners, we understand the importance of regular maintenance to keep our vehicles running smoothly. However, sometimes issues arise even after proper maintenance. One of these issues is car smoking after an oil change, which can be a result of several underlying causes. It’s essential to understand these causes to prevent further damage to your car and ensure it runs optimally.
The purpose of this article is to educate you on the causes, signs, and prevention methods of car smoking after an oil change. By the end of this article, you’ll have a better understanding of what to do if you experience this issue and how to avoid it in the future. So, let’s dive into the details and explore the causes of car smoking after an oil change.
Causes of Car Smoking After Oil Change

When you experience your car smoking after an oil change, it can be a result of several underlying causes. Here are some of the most common causes:
Overfilling of Oil
Overfilling of oil is a common cause of car smoking after an oil change. When the oil level is above the recommended level, it can cause excessive pressure in the engine, leading to oil leaks and smoke coming out of the exhaust.
Use of Low-Quality Oil
Using low-quality oil can also cause your car to smoke after an oil change. Low-quality oil can break down faster, leading to increased friction and heat in the engine. This, in turn, can cause the engine to overheat, leading to smoke coming out of the exhaust.
Clogging of the PCV Valve
The Positive Crankcase Ventilation (PCV) valve helps regulate the pressure in the engine and prevent oil leaks. However, if the PCV valve becomes clogged, it can cause the engine to produce smoke after an oil change.
Faulty Oil Filter
A faulty oil filter can also cause your car to smoke after an oil change. If the oil filter is clogged or damaged, it can prevent oil from flowing properly through the engine, leading to increased friction and heat, and smoke coming out of the exhaust.
Worn Out Engine Parts
Lastly, worn-out engine parts can cause your car to smoke after an oil change. If engine parts such as piston rings, valve guides, or cylinder walls are worn out, they can allow oil to seep into the combustion chamber, leading to smoke coming out of the exhaust.
By understanding these causes, you can take the necessary precautions to prevent car smoking after an oil change. In the next section, we’ll discuss the signs to lookout for if you suspect your car is smoking after an oil change.
Signs of Car Smoking After Oil Change
Car smoking after an oil change can be alarming, and it’s essential to recognize the signs to prevent further engine damage. Here are the most common signs of car smoking after an oil change.
Blue or Grey Smoke from the Exhaust
One of the most common signs of car smoking after an oil change is blue or grey smoke coming from the exhaust. This smoke is a result of burning oil, which can be caused by a variety of factors, including overfilling of oil, clogged PCV valve, or worn-out engine parts. If you notice blue or grey smoke coming from your exhaust, it’s crucial to get your car checked by a professional mechanic immediately.
Unusual Engine Noises
Another sign of car smoking after an oil change is unusual engine noises. These noises can indicate engine wear and tear, which can be exacerbated by low-quality oil or incorrect oil levels. If you hear any unusual engine noises after an oil change, it’s vital to get your car checked by a professional mechanic.
Decrease in Engine Performance
Car smoking after an oil change can also result in a decrease in engine performance. This can manifest as reduced acceleration, stalling, or difficulty starting your vehicle. If you experience any of these symptoms, it’s essential to get your car checked by a professional mechanic to prevent further damage to your engine.
Burning Smell from the Engine
Finally, a burning smell from the engine can also be a sign of car smoking after an oil change. This smell can indicate oil leaking onto the engine or other engine components, which can be caused by a faulty oil filter or worn-out engine parts. If you smell burning coming from your engine, it’s crucial to get your car checked by a professional mechanic immediately.
How to Prevent Car Smoking After Oil Change
As the saying goes, prevention is better than cure. The same applies to car smoking after an oil change. To prevent this issue from occurring, there are some simple steps you can take:
A. Use High-Quality Oil
Using high-quality oil is essential for the health of your engine. Low-quality oil can cause clogging in the engine, leading to car smoking after an oil change. Make sure to use oil that meets the requirements of your vehicle and change it regularly.
B. Change Oil Filter Regularly
The oil filter plays a crucial role in keeping the engine clean and preventing debris from entering it. Over time, the filter can become clogged, reducing its effectiveness. It’s essential to change the oil filter regularly to ensure it’s functioning correctly and prevent car smoking after an oil change.
C. Check Oil Levels Before and After Oil Change
Before changing the oil, make sure to check the oil levels. After the oil change, check the levels again to ensure there are no leaks or other issues. Low oil levels can lead to engine damage and car smoking after an oil change.
D. Regular Maintenance of Engine Parts
Regular maintenance of engine parts can prevent car smoking after an oil change. Faulty parts, such as the PCV valve or worn-out engine parts, can cause issues with the engine’s performance, leading to car smoking after an oil change. Regular maintenance can help you identify these issues early and prevent further damage to your vehicle.
By following these simple steps, you can prevent car smoking after an oil change and keep your engine running smoothly. Remember, prevention is key to maintaining the health of your vehicle and avoiding costly repairs in the future.
