The moment you get your car serviced, you expect it to run smoothly and efficiently. However, sometimes, despite getting a fresh oil change, your car may start running rough. This can be frustrating and worrisome, especially if you’re not sure what’s causing the issue. In this article, we’ll explore the reasons why your car might be running rough after an oil change and what you can do to resolve the problem.
Common Reasons Why Your Car Might Be Running Rough After an Oil Change
There are several reasons why your car might be running rough after an oil change. Here are some common causes:
1. Incorrect Oil Type or Quantity
If the wrong type or quantity of oil is used during the oil change, it can cause your car to run rough. Make sure to check your car’s manual to determine the recommended oil type and quantity.
2. Faulty Oil Filter
A faulty oil filter can cause your car to run rough. If the filter is clogged or damaged, it may not be able to filter the oil properly, leading to poor engine performance.
3. Low Oil Pressure
If the oil pressure is too low, it can cause your car to run rough. This can be due to a variety of reasons, including a faulty oil pump, a clogged oil filter, or worn-out engine components.
4. Dirty or Clogged Air Filter
A dirty or clogged air filter can cause your car to run rough. Make sure to check and clean or replace the air filter regularly to ensure proper engine performance.
5. Faulty Spark Plugs
Faulty spark plugs can cause your car to run rough. If the spark plugs are worn out or fouled, they may not be able to ignite the fuel properly, leading to poor engine performance.
6. Worn-Out Engine Components
Worn-out engine components, such as piston rings or cylinder walls, can cause your car to run rough. Over time, these components can wear out and cause the engine to lose compression, leading to poor engine performance.
7. Faulty Fuel Injectors
Faulty fuel injectors can cause your car to run rough. If the fuel injectors are clogged or dirty, they may not be able to spray the fuel properly, leading to poor engine performance. (See Also: How Many Miles Does Synthetic Blend Oil Last? – Lasting Longer)

A faulty oxygen sensor can cause your car to run rough. If the oxygen sensor is faulty, it may not be able to detect the proper air-fuel mixture, leading to poor engine performance.
10. Faulty Catalytic Converter
A faulty catalytic converter can cause your car to run rough. If the catalytic converter is clogged or faulty, it may not be able to convert the exhaust gases properly, leading to poor engine performance.
