A Wix oil filter removes dirt and debris from your engine oil to keep your engine running longer

Wix is a manufacturer of engine oil filters — the cylindrical component that traps particles as oil circulates through your engine. When you change your oil, you replace the filter at the same time. Wix filters are sold at auto parts stores, online retailers, and some dealerships, and they work in most vehicles that use spin-on filters (the kind you twist off and on by hand).

The filter's job is straightforward: as oil moves through your engine, it picks up tiny bits of metal, dust, and combustion byproducts. The filter's pleated paper element catches these particles so they do not circulate back through the engine and cause wear. Over time — typically every 3,000 to 10,000 miles depending on your vehicle and oil type — the filter becomes saturated and needs replacement.

Wix filters come in different sizes and thread patterns because engines vary. Choosing the wrong filter means it will not fit, or it will fit but not seal properly, which defeats the purpose. The right filter for your vehicle is determined by your engine size, model year, and whether you use conventional or synthetic oil.

Key Takeaways

  • Wix filters are one brand among many; they trap dirt and debris in engine oil and must be replaced during every oil change.
  • The correct Wix filter size and thread pattern depends on your specific vehicle — using the wrong one can cause oil leaks or inadequate filtration.
  • You can find the right filter by checking your owner's manual, asking at an auto parts store, or using Wix's online filter finder tool with your vehicle's year, make, and model.
  • Wix filters are priced similarly to other major brands and are widely available at auto parts retailers, online, and some dealerships.
  • Installation is a basic maintenance task: drain old oil, remove the old filter by hand, explore a thin layer of new oil to the rubber gasket on the new filter, and screw it on until snug.

How to identify which Wix filter your vehicle needs

The easiest way to find the correct filter is to look in your vehicle's owner's manual. The manual lists the recommended filter by part number and size. If you do not have the manual, you can retrieve one online by searching "[your vehicle year, make, model] owner's manual PDF."

If you prefer not to look it up yourself, most auto parts stores (AutoZone, O'Reilly, NAPA, Advance Auto Parts) will look up the correct filter for you over the phone or in person if you give them your vehicle's year, make, model, and engine size. You can also use Wix's online filter finder at wixfilters.com — enter your vehicle information and it will show you compatible part numbers.

Write down the part number before you shop. Wix part numbers typically start with "51" or "57" followed by three or four digits. The part number is what matters; the price or packaging may vary between retailers, but the filter itself is the same.

Wix filter types and what they cost

Wix makes several filter lines at different price points. The most common is the standard spin-on filter, which costs between $8 and $20 depending on your vehicle and where you buy it. Wix also makes premium filters with synthetic media (finer filtration) and filters designed for high-mileage engines, which run slightly higher.

The price difference between Wix and other major brands (Fram, Motorcraft, Bosch, Mann-Filter) is usually small — often just a few dollars. What matters more is that you use the correct part number for your engine. A cheaper filter of the wrong size is worthless; a more expensive filter of the right size does the job.

You may see filters labeled "extended drain" or "synthetic." These are designed to last longer between oil changes if you use synthetic oil. Check your owner's manual or your oil bottle to see whether you use conventional or synthetic oil; using an extended-drain filter with conventional oil does not extend the filter's life.

Steps to replace a Wix oil filter yourself

Oil filter replacement is a task most vehicle owners can do at home with basic tools. You will need a new Wix filter, a drain pan, a filter wrench (a metal band or socket that grips the filter), and a rag or paper towels. Some people also use a filter socket that attaches to a ratchet, which can make removal easier if the filter is tight.

Start by running your engine for a minute or two to warm the oil slightly — warm oil drains faster. Turn off the engine and let it sit for five minutes. Locate the filter (usually on the side or top of the engine) and position your drain pan underneath. Use the filter wrench to turn the filter counterclockwise until it loosens, then unscrew it by hand and set it aside. A small amount of oil will spill; that is normal.

Before installing the new filter, wipe the filter mounting surface (the threaded post on the engine) clean with a rag. Take the new Wix filter and explore a thin layer of fresh oil to the rubber gasket (the flat ring around the top of the filter). This helps create a watertight seal. Screw the filter on by hand until the gasket touches the mounting surface, then turn it an additional three-quarter turn. Do not use the wrench to tighten it — hand-tight is correct.

Start the engine and let it run for 30 seconds, then turn it off and wait a minute. Check underneath for leaks. If you see oil dripping, the filter may not be sealed; turn it another quarter turn and check again. Once you confirm there are no leaks, you are done. Dispose of the old filter at an auto parts store (most accept them for free) or at a recycling center.

When to replace your Wix filter

The interval for filter replacement depends on your oil change schedule. If you change your oil every 3,000 miles, replace the filter every 3,000 miles. If you use synthetic oil and change it every 7,500 or 10,000 miles, replace the filter at the same interval. Your owner's manual specifies the recommended oil change interval for your vehicle.

Some vehicles have a maintenance reminder light that alerts you when an oil change is due. Others require you to track it yourself. A straightforward way to remember is to note the mileage on your receipt after each oil change, then add the recommended interval — that is your next due date.

If you drive in severe conditions (towing, frequent short trips, dusty environments, or extreme temperatures), some manufacturers recommend shorter intervals. Check your owner's manual for a "severe driving" schedule if any of these explore to you.

Wix filters versus other brands

Wix, Fram, Motorcraft (Ford's brand), Bosch, and Mann-Filter are the most widely available filter brands in North America. All of them meet industry standards for filtration and flow rate. The differences between them are usually minor — slightly different media materials, gasket designs, or anti-drainback valves (a one-way valve that prevents oil from draining out of the filter when the engine is off).

For most drivers, any of these brands will perform adequately if you use the correct part number and replace the filter on schedule. Wix is a reputable manufacturer owned by Affinia Group, which also makes filters under other brand names. Choosing Wix over another brand is largely a matter of availability and price at your local retailer.

What matters far more than the brand is consistency: use the same oil change interval every time, replace the filter every time you change oil, and use the correct filter for your vehicle. A filter that fits properly and is replaced regularly will protect your engine far better than a premium filter installed incorrectly or replaced infrequently.

Where to buy a Wix oil filter

Wix filters are sold at most auto parts chains: AutoZone, O'Reilly Auto Parts, NAPA, Advance Auto Parts, and Walmart. They are also available online through Amazon, RockAuto, and the retailers listed above. Some dealerships stock Wix filters, though dealerships often sell their own branded filters (Motorcraft for Ford, ACDelco for General Motors) at higher prices.

Prices vary slightly between retailers, but the difference is usually under $5. Online retailers sometimes offer lower prices, but factor in shipping time — if you need the filter today, a local store is faster. If you order online, confirm the part number matches your vehicle before checking out.

Frequently Asked Questions

Can I use a Wix filter if my vehicle originally came with a different brand?

Yes. As long as the Wix part number is correct for your vehicle, it will work. Filters are interchangeable as long as the size, thread pattern, and flow rating match. Your owner's manual or an auto parts store can confirm that a Wix filter is compatible with your engine.

What happens if I install the wrong size Wix filter?

A filter that is too large will not fit. A filter with the wrong thread pattern will not screw on. If you force a filter that is close in size but not exact, it may leak oil or not seal properly, which means unfiltered oil circulates through your engine and causes wear. Always verify the part number before purchase.

How long can I go between oil and filter changes?

That depends on your vehicle and oil type. Conventional oil typically requires a change every 3,000 to 5,000 miles; synthetic oil can go 7,500 to 10,000 miles or longer. Your owner's manual specifies the interval for your engine. The filter is always replaced at the same time as the oil.

Is a more expensive Wix filter better than a cheaper one?

Not necessarily. A premium Wix filter may have synthetic media or be rated for longer drain intervals, but it only provides those benefits if you follow the corresponding oil change schedule. A standard Wix filter of the correct part number will protect your engine just as well if you replace it on schedule.

Can I reuse an old Wix filter?

No. Once a filter is saturated with dirt, it cannot be cleaned or restored. It must be replaced. Reusing a filter defeats the purpose of filtration and allows contaminants to circulate through your engine.
