Have you ever had the experience of expecting your car to operate smoother after an oil change, only to find that it began vibrating? The car shaking after an oil change signals that something went wrong during the oil change.  

In this article, we will look at some of the reasons that could be leading to vibrations in your car after an oil change.

Causes of Car Shaking After Oil Change 

Here are the most prevalent reasons why your car shakes after an oil change. Some of these are also reasons for a white smoke after changing oil

Overfilled oil 

Adding more oil to the oil tank might cause an increase in crankcase pressure. At high RPM, the crankcase is dipped into the oil, resulting in a froth formation inside the oil. This causes air bubbles in the oil, resulting in poor lubrication of engine components. Because the engine parts are not performing optimally, this might produce vibrations and instability in the system. 

Use a dipstick to test the oil level; anything marked above the maximum level is considered overfilled oil. To avoid overfilling the oil tank, drain the old oil before pouring in the new oil. 

Clogged Air Filter 

The air filter is in charge of keeping the engine clean by preventing external contaminants from entering the engine components. Most automobile owners forget to clean or replace the air filter when changing the oil in their vehicles. When an air filter becomes old, a lot of dust and debris gets lodged in it, causing the air filter to choke. This could cause strong vibrations in the engine following an oil change. 

Rinse the air filter with soap and water to clean it. If your air filter is too old, make sure to have it replaced as soon as possible. Also, air filters come in a variety of sizes; make sure you use the suitable size and shape filter. 

Low oil level 

If your engine oil is low, you may notice vibrations in your vehicle. When the engine’s oil level is low, it can cause greater friction and wear and tear on engine components. This causes engine components to malfunction and causes vibrations in the vehicle. 

If you recently filled your tank and it’s getting empty more frequently, check for any oil leaks due to a damaged oil pan, clogged oil filter, or damage in the gasket. Make sure your drain plug is correctly sealed after you have drained your engine oil.  

Disconnected Oil Pressure Sensor 

This can happen if you remove the oil pressure sensor to clean the dirt and debris on it, but then don’t replace it properly. The oil sensor is responsible for providing accurate readings of your oil level; if it is reinstalled incorrectly, this can result in incorrect oil level readings. 

As a result, you will not receive an accurate readout of your engine’s oil level or oil pressure. If your oil pressure or oil level is low, your engine components may vibrate because they are not functioning optimally. 

Wrong Viscosity Oil 

Using improper oil in your engine can damage its components. High-viscosity oil is typically utilized in hot climates and in high-performance automobiles. If you used improper viscosity oil for your engine during the oil change, this might cause your engine to overheat and cause friction at specific temperatures, causing the car to shake or vibrate. 

Consult your mechanic to figure out the best viscosity oil for your engine. If you have a high-performance vehicle, you should also use synthetic oil rather than conventional oil. 

Bad Spark Plugs

The spark plug is in charge of providing the initial ignition to start the engine. Spark plugs might fail over time due to dirt, oil fouling, slow driving, or idling for too long. Faulty spark plugs can result in an unburnt fuel-air mixture inside the combustion chamber.

This unburned fuel will cause engine power issues by changing the RPM and causing frequent misfires. 

Because of the frequent misfires, the car may vibrate or tremble while driving. Make sure you get your spark plug changed or repaired.

What To Do When A Car Is Shaking After an Oil Change? 

The first thing you should do is turn off your engine and investigate the source of the vibrations in your vehicle.

  1. Check the oil level with a dipstick; if the oil level is higher than the ‘F’ (full) ‘Max’ indication, the oil is overfilled. If it is less than ‘L’ (low) / ‘Min’, your oil level is too low. Make sure the oil level in your tank is anywhere between the upper and lower levels. 
  2. Check that your Mass Airflow Sensor (MAF), Manifold Absolute Pressure (MAP), and Oxygen (O2) sensors are properly mounted and functioning. 
  3. Make sure to clean or replace your air filter if it is too clogged or outdated. Check if the spark plug is connected properly. 

FAQ’s on Car Shaking After Oil Change 

Overfilling your engine oil is not recommended. This is due to the fact that it might put extra pressure on the crankcase, causing oil to spill into the engine. This can generate air bubbles in the oil, causing the car to shake more often. Overfilled oil can also emit a burning oil smell through the vents.

Yes, a dirty air filter might cause your car to shake after you change the oil. We rarely have the air filter cleaned, which results in a buildup of dirt and debris. This causes the engine to choke, resulting in vibration in the car.

Conclusion 

To summarize, if your car is shaking after an oil change, check the oil level. If the oil level is correct, there could be a problem with your air filter; make sure you inspect it and have it repaired. You should also use the correct viscosity oil for your engine.  

If you are using the correct oil and your oil level is normal, it is possible that your oil pressure sensor was not properly reinstalled. Make certain that it is properly reinstalled, as the oil pressure sensor was most likely giving you incorrect readings.
