My Car Runs Rough After Oil Change: Possible Causes and Solutions

Have you recently changed your car's oil and now find that it runs rough? You are not alone if this occurs.

Many car owners have experienced this issue and can be quite frustrating.

Your vehicle may experience various problems after an oil change, such as rough idling, poor acceleration or even stalling.

In this article, we'll look into the common causes of a rough-running engine after an oil change and offer solutions on how to resolve them.

 

Low-Quality Oil

One of the primary causes of poor engine performance after an oil change is using low-quality oil.

Cheap oil may not meet manufacturer specifications or have proper additives to protect your engine, leading to decreased power and rough idling.

If you believe low-grade oil is causing your engine to run rough, we suggest replacing both with high-grade, manufacturer-recommended products for optimal performance and protection.

If you are unsure as to what oil to choose, you can consult your owners manual or speak to a mechanic online or locally.

 

Wrong Viscosity

Using the wrong viscosity oil can result in uneven engine performance after an oil change.

Viscosity refers to how easily the oil flows through your engine; too thick or thin can cause friction and decreased performance.

You can consult your car owner's manual for guidance on selecting the correct viscosity of oil for use, and ensure you use only that type and viscosity during each change.

 

Clogged Oil Filters

A clogged oil filter can restrict oil flow to your engine, leading to decreased performance and rough idling.

When changing oil, it's essential to replace your car's oil filter in order to avoid clogs and guarantee proper oil circulation.

Furthermore, a neglected clogged filter could eventually cause engine damage over time or cause leaking after an oil change; so it's essential that this issue be addressed right away.

If you are unsure about this we recommend you speak to a mechanic locally or online.

 

Contaminated Oil

Contaminated oil can lead to poor engine performance after an oil change.

Dirt, debris and metal shavings accumulate over time in your engine, leading to damage and poor performance.

When changing your car's oil, make sure all old oil is completely drained out and replaced with fresh, clean fluid.

Furthermore, inspect the oil for contaminants prior to adding it back into your engine.

 

Loose or Damaged Parts

If your oil filter or pan was not installed correctly, this can lead to oil leaks and decreased performance.

Furthermore, damaged spark plugs or ignition coils in your car may result in poor acceleration as well as rough idling.

If you suspect these issues are the source of your engine running rough, we suggest taking it to a trusted mechanic for inspection.

 

Conclusion

If your car is a running rough or jerking after an oil change, it can be discouraging and worrying.

But understanding the common causes of rough engine performance after an oil change and taking steps to prevent them will help safeguard against engine damage and ensure smooth running in your car.

By using high-quality oil and filters, using the correct viscosity for oil, inspecting for contaminants, and making sure all parts are installed correctly, you can minimize engine lag and enjoy a reliable ride with improved smoothness and dependability.
