Oil Filter Cause Misfire? Reasons? [Explained]

Can an oil filter cause a misfire? The answer is not as straightforward as you might think. There are many reasons that could lead to your car’s engine misfiring, and it’s important for you to understand how this happens in order to be able to diagnose the problem correctly. In this blog post, we will discuss whether an oil filter can cause misfires, and what are other reasons causing an engine misfire.

Can oil filter cause misfire?

No, an oil filter cannot cause a misfire . If your car is experiencing engine misfires, it’s likely that the problem originates from something else related to the engine. For example, if you notice a loss of power when driving or hear knocking noises coming from under the hood while idling in parking, this could be caused by a problem with the engine. Therefore, the answer to the question an oil filter cause misfire is, No.

Engine misfire: causes and symptoms

What are other reasons leading to an engine misfire? Here are the top 5 causes and symptoms :

  1. Damaged spark plugs or wires.
  2. Faulty fuel injectors (which can lead to a loss of power).
  3. Dirty or worn out air filter which may cause the engine not to get enough air needed and it will misfire as a result. The same goes for dirty fuel filter. It would also be possible that there is too much oil in your engine, which could be leading to the misfire.
  4. Dirty or worn out ignition system and faulty engine timing can also cause your car’s engine to misfire.
  5. Clogged fuel line will result in a loss of power as well as a possible misfire.

Bad oil filter symptoms

The symptoms of a bad oil filter include:

  • A decrease in performance.
  • The engine is louder than usual, or the sound changes to a rattling noise.
  • Engine oil leaks from seals and gaskets on valves and piston rings, causing smoke from oil getting burned as it travels through the combustion chamber with the exhaust gases. This can also lead to increased fuel consumption.
  • A change in the color of oil or smoke coming out with exhaust gases, indicating a problem with fuel and air combustion due to an inefficient filter.
  • The oil typically becomes dirty more quickly than normal. It can also become viscous and start leaking past worn seals into places where it is not supposed to be like the engine’s crankcase.
  • The oil filter may have become too clogged up with contaminants to allow the engine to run properly, which is why you would hear a rattling noise and see smoke from exhaust gases as well as a change in engine performance.

Can an oil change cause a misfire?

No, an oil change will not cause a misfire, because it doesn’t affect the combustion chamber.

A misfire is most likely caused by worn valve guide seals and guides, but worn rings and cylinders can also allow oil to enter the combustion chamber which will cause a misfire. Replacing the spark plug will cure this problem, but it won’t cure an oil consumption issue because that’s probably coming from worn valve seals and guides.

This means you’ll need to replace the camshaft, lifters, and timing chain (or gears) as well before addressing the oil consumption issue. Therefore, the answer to the question can oil change cause misfire is, No.

Can an oil change fix misfire?

No, an oil change will not fix misfires. Replacing the spark plug with a new one is usually enough to solve this problem if it’s caused by worn-out parts (like valves or rings), but that doesn’t address engine problems like camshaft and timing chain issues which can also lead to a misfire. Therefore, the answer to the question can oil change fix misfire is, No.

What is the most common cause of a misfire?

The most common cause of a misfire is that the car’s fuel-air mixture was not optimized for the engine, as we discussed earlier in this article. That can happen if you’re driving uphill or downhill with your foot on the gas. It will also naturally occur at high speeds like when racing down a drag strip where it takes less time for the air to enter and leave your engine.

What does a bad oil filter sound like?

A bad oil filter will make a rattling sound when the vehicle is running. You will also notice that the engine is louder than normal. It can even sound like there are metal objects inside your exhaust system and you may see smoke coming from your tailpipe which indicates a problem with fuel combustion due to an inefficient filter.


Misfires are often caused by issues related to the engine, and oil filters do not cause misfires.

There are many potential causes of a car’s engine misfiring, such as low fuel pressure or incorrect timing. A faulty part in your distributor can also lead to a problem with misfires.

It’s important to use a good quality oil filter, like the ones from Mobil1 oil filters, that will not only protect your engine but also keeps it running smoothly and reliably for long periods of time.
