How to Change Oil Filter

You need to change the oil filter in your car, as it is very important for vehicle maintenance operations that all car owners must complete. Mechanics across the country provide oil filter replacement services in conjunction with engine oil changes. In this article, we’ll walk through the process of changing the oil filter step by step.

How to Change Oil Filter

If you’re wondering how to change your car’s oil filter, you should first understand what an oil filter is and why it’s so vital.

Oil filters remove solid particles and impurities from the oil that circulates through the vehicle’s engine parts. Contaminated oil in vehicles can damage the engine, reduce fuel consumption, and cause exhaust problems.

Oil filters do not last forever. After a specified amount of vehicle use, you must replace this device with a new one. Most people get their car’s oil filters changed by their mechanic during an oil change or car servicing and maintenance. Those who are confident with vehicle maintenance may choose to change their oil filter.

Not sure if you can change your oil filter? This article will walk you through the process step by step so you can decide whether to do it yourself or hire a professional to change your oil filter.

What Is a Car Oil Filter?

An oil filter is a mechanical device that is commonly seen in modern car combustion engines. Its goal is to remove pollutants and impurities from engine oil to achieve optimal engine performance.

Oil lubricates the working elements of an engine, allowing it to run smoothly. However, when the engine operates, combustion within the engine releases pollutants that accumulate in the engine oil. If these impurities remain unfiltered in the oil, they will form small hard particles that might damage the oil engine.

How Does a Car Oil Filter Work?

An oil filter is sealed in a metal container with a sealing gasket and is closely linked to the engine block. The engine oil pump forces the unfiltered oil into the oil filter after it has passed through the engine.

The oil is then pushed through the perforations in the oil filter and through the synthetic fiber cartridges inside the filter. These cartridges capture the particles while allowing clean oil to pass through the filter’s inlet and back into the car’s oil pan.

Importance Of Changing Your Oil Filter

The filter material in the oil filter will become clogged with trapped particles over time. When this occurs, the filter is unable to function properly and oil is not filtered. Unwanted particles in the oil cause engine damage.

Most people understand the importance of changing their automobile oil, but did you realize that changing their oil filter is just as important? Engine damage caused by filthy oil can also cause variations in fuel consumption, unhealthy exhaust fumes, unsettling noises under the hood, and acceleration issues.

What you’ll need to change your oil filter

Gather the materials required to change the oil and filter. Before changing the oil filter in a car, gather all of the necessary tools and supplies, which are:

  • The oil filter
  • A socket wrench
  • An oil filter wrench
  • Oil pan or bucket to catch the spilling oil
  • Jack, jack stand, axle stands, or ramps
  • Rags
  • Work gloves
  • New drain oil plug
  • Owner’s manual
  • New engine oil suitable for your vehicle and funnel

Procedure for Changing a Car’s Oil Filter

It is best to drain old engine oil before replacing the filter. This guarantees that the old oil is not over-contaminated. This means you’ll need to know how to change the oil in your automobile as well as the filter. Follow these procedures below to change your oil filter:

Before changing the oil, warm up the car:

Start the car and let it run for a few minutes, or go for a little drive. Such movement warms up the engine oil, allowing it to drain more efficiently.

Park the vehicle in a safe location:

This could be a driveway or a garage. The terrain must be level. Before changing the oil filter in an automobile, turn off the engine.

Use a jack or ramp to raise your vehicle:

To stabilize the car, use a jack stand. Do not go underneath the automobile, which is solely supported by a jack.

Locate the oil drain plug:

It is usually found beneath the car. You can locate the oil drain stopper by consulting the owner’s or repair handbook. Place a drain pan just beneath the oil drain plug. After you remove the oil plug, the oil should drain into the drain pan.

Use a socket wrench to remove the oil plug:

Before touching the oil plug, ensure that the engine is cool to the touch. Remove the oil plug with a socket wrench. Take care since the leaking oil may be hot.

After all of the oil has been drained, replace the drain oil cap:

To begin, screw the plug using your fingers. The socket wrench can then be used to tighten the plug. Overtightening the socket might result in thread damage. The exact torque specification can also be found in the repair manual.

Take off the old oil filter:

Begin by removing the filter from its mounting with the oil filter wrench. Some oil may flow if the filter becomes loose. Place an oil pan below to catch any spilled oil. Wear gloves because the oil that has escaped may be hot.

Take off the old oil filter:

Once the oil has been completely drained, carefully remove the oil filter using your hand or an oil filter wrench. Wipe a towel across the engine’s mounting surface to clean it and remove any old gaskets.

1Replace the oil filter:

Replace the oil filter and lubricate the O-ring seal. Insert the new filter and turn it halfway. To avoid deforming the replacement filter’s soft rubber gasket, do not over-tighten it. The gasket prevents oil leakage.

fill up with new oil in your vehicle:

Using a rag, clean the engine’s mounting surface. After replacing the oil filter, you can now replace the old oil with a fresh one. Pour in the new oil using a funnel. Check your owner’s manual for the proper amount, type, and grade of oil for your vehicle.

Examine for any leak:

Allow the engine to run for a few minutes to allow the oil to circulate properly. If you notice a leak, turn off the engine immediately and investigate the source of the leak.

Turn off the engine and use the dipstick to check the oil level:

Before placing the dipstick into the oil inlet, clean it first. Before screwing the cap back on, make sure the oil level is correct.

always take note of the current distance traveled by your vehicle to determine when the next oil and filter change will be.

Frequently Asked Questions

How often should your oil filter be replaced?

According to an old rule, replacing the oil filter in an automobile should be done every other oil change. Every automobile is unique. Many car manufacturers advocate changing the oil filter in the owner’s manual.

Vehicle oil changes are typically performed every 4,800 to 9,600 kilometers, depending on the vehicle. If you change your oil every 4,800 kilometers, you must replace your oil filter every 9,600 kilometers.

You can also ask a professional on how frequently an oil filter should be changed for a certain car model.

is it possible to change the oil filter without changing the oil?

Yes, as long as you top up the amount that spills out, you can change the oil filter without changing the oil completely. However, it’s ideal to do both at the same time, especially since the timing for oil filter changes corresponds to the interval for oil changes.

can I reuse the same oil filter?

No, you cannot use the same filter more than once. When a filter becomes clogged with debris and dirt particles, it must be replaced. Installing a used oil filter again will result in heavily polluted oil, which can seriously damage the engine.


Changing your oil filter is more than just maintaining your vehicle; it’s about keeping your engine strong and healthy. This simple yet often overlooked task is crucial for optimal engine performance and a longer lifespan.

By following a step-by-step guide and recognizing the significance of a clean oil filter, you empower yourself to care for your vehicle. Regular filter changes go beyond a routine; they are a commitment to your engine’s lasting well-being.
