Changing your oil filter is essential to maintaining your engine’s health and performance. As your engine runs, the oil collects dirt, debris, and contaminants. The oil filter traps these particles to prevent them from circulating through the engine. Over time, the filter becomes clogged and less effective, which can reduce oil flow and lead to increased engine wear or even damage. At Tech9 Auto Repair, we recommend replacing the oil filter during every oil change to ensure your engine stays clean, lubricated, and running smoothly.

At Tech9 Auto Repair, we recommend changing your oil filter every time you get an oil change. For most vehicles, this means every 3,000 to 5,000 miles when using conventional oil, or up to 7,500 miles with synthetic oil—depending on your driving habits and manufacturer guidelines. Regularly replacing the oil filter ensures clean oil circulates through your engine, improving performance and extending engine life. For exact intervals, always refer to your vehicle's owner's manual or consult with our technicians during your visit.

In most cases, you'll need a few basic tools: an oil filter wrench to loosen the old filter, a wrench to remove the oil drain plug, a drain pan to catch used oil, and gloves for safety. Some filters can be removed by hand, but an oil filter wrench makes the job easier and cleaner. At Tech9 Auto Repair, we have the right tools and expertise to do it quickly and correctly for you.

Changing an oil filter involves the following steps:

Warm the engine slightly to allow the oil to drain more easily.
Place a drain pan under the oil drain plug and remove it.
Remove the old oil filter using a filter wrench.
Apply a thin layer of clean oil to the gasket on the new filter.
Install the new filter by hand—tight but not overly tight.
Replace the drain plug and refill the engine with fresh oil.
Start the engine and check for leaks.
For best results and peace of mind, let Tech9 Auto Repair handle this process professionally.

The correct oil filter depends on your vehicle’s make, model, engine type, and year. You can find this information in your owner's manual or ask one of our experts at Tech9 Auto Repair. We’ll ensure you get the exact match to maintain optimal engine performance and avoid compatibility issues.

Used oil filters should never be thrown in the trash. They contain residual oil, which is harmful to the environment. At Tech9 Auto Repair, we responsibly collect and dispose of used filters through certified recycling programs to comply with environmental regulations.

Common signs include:

Reduced engine performance
Engine overheating
Dirty or dark oil
Decreased fuel efficiency
The oil pressure warning light turning on
If you notice any of these signs, it’s time to visit Tech9 Auto Repair for a quick inspection.

If you have the right tools and some mechanical knowledge, changing the oil filter is possible. However, improper installation or using the wrong filter can lead to engine damage or leaks. For your safety and your car’s health, we recommend having the service done by professionals at Tech9 Auto Repair.

Technically, yes—but it’s not recommended. Changing the oil filter without replacing the old oil defeats the purpose, as the new filter will immediately be exposed to dirty oil. For maximum benefit, change both the oil and the filter together, which we always do at Tech9 Auto Repair.

A clogged or dirty oil filter can restrict oil flow, leading to increased engine friction, overheating, and premature wear. Over time, it can cause severe engine damage and costly repairs. Regular oil filter replacement is a small investment that protects your engine in the long run.

While generic oil filters might fit, they often lack the quality and durability of OEM or premium filters. At Tech9 Auto Repair, we recommend using filters that meet or exceed manufacturer specifications to ensure reliable performance and engine protection.
