Understanding the Issue

Mechanic Looking At Car Engine

What does it mean when your car runs rough?

When we say a car is “running rough,” we’re generally referring to irregularities in the engine’s performance. This could manifest as stuttering, shaking, or the engine not providing enough power.

How does an oil change relate to this issue?

An oil change is a routine maintenance task that involves replacing the old engine oil and oil filter in your car. However, if not done correctly, it can lead to issues like your car running rough.

Common Causes of Rough Running After Oil Change

Incorrect Oil Type

Using the wrong type of motor oil for your car can cause the engine to run rough. Each vehicle requires a specific type of oil with a certain viscosity. If the wrong oil is used, it can cause inadequate lubrication, leading to engine problems.

Oil Contamination

If the old oil isn’t completely drained during the oil change, the new oil can get contaminated. This contamination can cause the engine to run rough.

Oil Filter Issues

The oil filter needs to be replaced during an oil change. If the old filter is left in place, or the wrong filter is used, it can restrict oil flow and cause the engine to run rough.

Problems with the Oil Pump

If the oil pump is damaged or malfunctioning, it can lead to low oil pressure, causing the engine to run rough. This issue might become apparent after an oil change.

How to Fix a Car Running Rough After Oil Change

The first step is to check the oil level. If there’s too much or too little oil, it can cause your car to run rough. Adjust the oil level as necessary.

Ensuring the Correct Oil Type

Check your vehicle’s manual to ensure the correct oil type was used. If the wrong oil was used, you’ll need to drain it and refill with the correct type.

Checking the Oil Filter

Inspect the oil filter. If it’s old or the wrong type, replace it with the correct filter for your vehicle.

Seeking Professional Help

If you’ve tried the above steps and your car is still running rough, it’s time to seek professional help. A certified mechanic online or locally can diagnose and fix the issue.
