How Often to Change Car Oil Filter

by Chris Lewis.

Oil is required for the proper operation of your engine. So your oil filter is critical in ensuring that your oil can accomplish this.

An oil filter saves your engine from possible harm by eliminating impurities (oxidized oil, metallic particles, dirt, and so on) that might collect in motor oil as a result of engine wear. Using high-quality synthetic oil will help prolong the life and efficiency of your oil filter. Because synthetic motor oil is even more refined & distilled than conventional oil, it'll last longer and it is less susceptible to clogging your filter.

The oil filter may seem to be nothing more than a basic container, but it performs a crucial function in ensuring that your automobile never leaves you stranded on the roadside. The actual filter is contained inside the can. Your car's engine pumps oil through the filter as you drive, purifying the oil before it returns to the engine.

The filter eliminates dirt and microscopic metal particles from the oil, ensuring that only clean oil comes into touch with the engine's moving components. The absence of dirt and metal flecks not only keeps the system from clogging, but also prevents the microscopic particles from scraping, scratching, or denting, the engine components.

What Exactly is An Oil Filter?

An oil filter is an important component of your engine's working system, and it, as motor oil, must be replaced on a regular basis to guarantee your car operates effectively.

While cycling through an engine, motor oil collects grit and grime, and oil filters remove this filth to guarantee the engine gets the lubrication it requires. If the filter is not updated, these pollutants block it, resulting in unclean, corrosive motor oil that, if remain untreated, ruins an engine's moving components.

What Is the Purpose of an Oil Filter?

An oil filter in vehicles sustains motor oil flow while capturing impurities and metallic particles and preventing them from flowing through the engine.

Without it, dirt and other microscopic undesired pieces, such as metal particles, would freely enter the engine assembly, causing serious damage to the engine owing to blockages and other waste. If the damage stops engine components from moving, your car will not be able to move. Contaminants might also affect your vehicle's oil demand efficiency.

How Often Should a Car's Oil Filter Be Changed?

Each automobile manufacturer provides advice on how frequently oil filters must be changed and what oil might be used in their engines. If you don't have your car owner's handbook, you may easily get this information on the manufacturer's website or forums of other owners. You must stick to it after you've discovered it. You may use higher-quality filters and oils to increase the time between changes, but it is recommended to stay with the estimates of several engineers who spent hours, days, and even years designing the model and its motor and are much more informed about it than anybody else. Better grade oils will extend the life of an oil filter, but pay attention to the manufacturer's verifiable information.

An oil filter typically has a mileage range of 5 to 8 thousand miles. Some may propose replacing the oil filter per 10,000 miles, but this is much too long for most vehicles. Previously, oil filters, as well as oils, were supposed to be replaced every 3,000 miles. Yet, technology has evolved in this area as well as in others, and we no longer have to go through the inconvenience as often. Newer versions feature built-in mechanisms that alert you when it's time to replace the oil filter. Check your vehicle's owner's handbook to determine whether such a system is built into the model you're driving. On the dashboard, there must be a light for it.

Every car has an oil signaling bulb, but you should keep in mind that in most instances, it is designed to alert you if you unexpectedly lose oil pressure. So, to tackle the question "How frequently should I replace my oil filter?" we can simply state that you should plan an oil filter change and also an oil change alongside every 5-8 thousand miles.

Elements that might reduce the life of your oil filter include:

  • Aggressive driving manner;
  • Extensive stop-and-go traffic (in the city);
  • Severe weather conditions;
  • Driving with large loads;
  • Towing;

According to who you ask, the apparently simple topic of how frequently you should change oil filters in automobiles may yield a broad range of replies. Oil filters should be replaced more or less every time your oil is changed, according to car manufacturers. Many gears and oil manufacturers, on the other hand, recommend replacing oil filters with each and every oil change, which should be done every 3,000 miles or 3 months.

Here are some pointers from our expert technicians for regular oil filter repair and upkeep:

  • Replace oil filters with each oil change. While we agreed with oil companies that you should replace your oil filters whenever you change your oil, we disagree on how frequently you should do so. The 3,000-mile rule is a fallacy unless you're driving an ancient car with an essentially prehistoric engine that doesn't filter particles as well. Every car is different, but the average number of miles to wait is about 7,500. Check your owner's handbook for information on how to properly maintain your vehicle's oil filter.

  • If the Repair Engine light comes on, you might have to change the oil filter sooner than expected. While the Service Engine light might be caused by a variety of factors, it's a smart option to rule out the less serious possibilities before shelling out big bucks for diagnostics and fixes. When the light illuminates, it means the engine system isn't performing as efficiently as it should, which might also mean there's a lot more filth and debris in the air. This might cause your oil filter to clog faster than normal.

The oil filter is an essential component of your engine's functioning. It eliminates grit and filth from your oil, preventing such pollutants from entering the engine as oil circulates and lubricates its components. Because oil filters are quite affordable, most people advocate replacing them with every oil change as a preventive step.


Here are some frequently asked questions about automotive oil filters. Let us respond to them so you can understand your oil filter better.

1. How Much Will It Cost to Replace an Oil Filter?

A normal oil filter change may range from $20 to $125 at an auto repair shop. This cost of replacement will include three charges, along with the cost of:

  • Engine oil (varies based on the kind of oil used in the vehicle, such as synthetic motor oil or ordinary oil)
  • A fresh oil filter (fuel filter)
  • The labor cost at the motor shop
  • Extra service fees if your technician discovers additional issues such as engine wear, a broken oil pan, and so on.

Before replacing your oil filter, consult your car's owner's handbook, which is given by the manufacturer, to determine the suggested replacement time. It will save you from having to pay for an oil filter change that was unnecessary.

2. What Is Involved in an Oil Filter Change?

When you visit an auto service facility or repair service for an oil filter change, both the oil filter and the engine oil must be replaced. However, this is not always the situation.

If the gasoline filter is in excellent condition, just add fresh engine oil. However, if your oil filter is outdated, you won't be able to replace the engine oil completely.


Replacing the old oil with new engine oil and not the fuel filter is wastage of time. Once the fresh oil has passed through the utilized fuel filter, your clean oil becomes filthy and seems to be old oil.

That is why your technician will empty your old oil first.

3. Why Do I Need to Replace My Oil Filter on a Regular Basis?

Because it collects a lot of impurities including metal particles, filth, and carbon dust, your car's engine oil filter will progressively get clogged over time. Updating the oil filter improves the life of the engine and retains the engine oil clean.

A clogged engine oil filter reduces the quantity of clean oil running through it, necessitating an oil filter service as well as fresh oil.

Last Thoughts

Evidently, the subject of "how frequently to replace oil filter" is not as simple as it seems. After all, there are several variables to consider. However, it is still necessary to replace this component in conjunction with your normal oil change.

Remember that the oil filter eliminates sand and filth from your oil, making it a key component of your car's engine functioning. The good news is that oil filters are reasonably priced, so you can safeguard your vehicle against engine wear (cost damage) in the long term.
