Ford oil filters are made by several manufacturers, and the right one depends on your specific Ford model year and engine
Ford does not make its own oil filters — the company contracts with suppliers like Motorcraft (Ford's parts brand), Fram, and Purolator to manufacture them. When you buy a filter at a Ford dealership, you are usually getting a Motorcraft filter, which is engineered to Ford's specifications. You can also buy aftermarket filters from other manufacturers that meet Ford's standards, often at a lower cost. The key is matching the filter to your exact engine size and model year, because a filter designed for a 2.0-liter engine will not fit a 3.5-liter engine in the same vehicle generation.
The filter part number tells you everything. Ford assigns a unique part number to each filter — for example, FL-400S or FL-820S — and that number is printed on the box and sometimes on the filter itself. If you know your Ford's year, make, model, and engine size, you can look up the correct part number in Ford's parts catalog or ask a parts counter. Many auto parts stores will also cross-reference the number for you if you give them your vehicle identification number (VIN).
Key Takeaways
- Ford oil filters are made by Motorcraft, Fram, Purolator, and other suppliers, not by Ford itself, and the correct filter depends on your engine size and model year.
- Each Ford filter has a unique part number that ensures you get the right fit and flow rate for your specific engine.
- You can buy Motorcraft filters at a Ford dealership or aftermarket filters at auto parts stores, as long as they meet Ford's specifications.
- The filter's micron rating and bypass valve pressure are engineered for your engine, so using the wrong filter can reduce oil flow or allow unfiltered oil to circulate.
How to find your Ford's correct filter part number
Start with your vehicle identification number (VIN), which is printed on your registration, insurance card, or the dashboard on the driver's side. The VIN contains your model year, engine code, and other details that determine which filter you need. You can enter your VIN into Ford's official parts website (parts.ford.com) or give it to a parts counter at a Ford dealership, and they will pull up the exact part number in seconds.
If you do not have your VIN handy, you can also look it up by year, make, model, and engine size. For example, a 2018 Ford F-150 with a 5.0-liter V8 needs a different filter than a 2018 F-150 with a 3.5-liter EcoBoost. Auto parts stores like AutoZone, O'Reilly, and NAPA all have online lookup tools where you enter these details and the system shows you compatible filters from multiple brands.
Motorcraft filters versus aftermarket alternatives
Motorcraft is Ford's official parts brand, and Motorcraft filters are designed and tested to Ford's exact specifications. They carry Ford's warranty and are may provide to fit your Ford engine. When you buy a Motorcraft filter at a dealership, you are paying for that engineering and the dealership's labor if something goes wrong. The cost is usually higher than aftermarket options.
Aftermarket filters from Fram, Purolator, Bosch, and other manufacturers are made to meet industry standards and often cost less. Many of them perform well and last as long as Motorcraft filters. The trade-off is that you are relying on the aftermarket manufacturer's quality control rather than Ford's, and if a problem occurs, you may have less recourse. Most mechanics and Ford owners use aftermarket filters without issues, but some people prefer the peace of mind that comes with the official part.
Understanding filter specifications: micron rating and bypass pressure
Every oil filter has two important specifications that affect how it works in your Ford engine. The micron rating tells you the smallest particle size the filter can trap — most automotive filters are rated between 10 and 25 microns. A lower micron rating catches more contaminants but also restricts oil flow slightly. Ford engineers choose a micron rating that balances filtration and flow for your specific engine.
The bypass valve pressure is the point at which the filter opens a valve to let unfiltered oil through if the filter becomes too clogged. If you use a filter with the wrong bypass pressure, you risk either restricting oil flow (if the pressure is too high) or allowing dirty oil to circulate (if it is too low). This is why using the correct part number matters — it ensures both specifications match your engine's design.
When to replace your Ford oil filter
Ford recommends changing your oil filter every time you change your oil. For most modern Fords, that is every 10,000 miles or once a year, whichever comes first — though some newer models with synthetic oil can go 15,000 miles between changes. Check your owner's manual for your specific Ford's interval, because it varies by engine type and oil grade.
You will know a filter needs replacement if you see a low oil pressure warning light on your dashboard, or if your mechanic tells you the filter is clogged during a service. A clogged filter forces the bypass valve open, which means unfiltered oil is circulating through your engine. Replacing the filter is inexpensive compared to the cost of engine damage from dirty oil.
Where to buy Ford oil filters
Ford dealerships stock Motorcraft filters and can install them during an oil change service. You pay for the part, the labor, and the dealership markup. Many dealerships offer service packages that include the filter and oil at a set price.
Auto parts stores like AutoZone, O'Reilly, NAPA, and Advance Auto Parts carry both Motorcraft and aftermarket filters. You can buy the filter alone and install it yourself, or many of these stores offer installation services for a fee. Online retailers like Amazon also sell Ford filters, though you should verify the part number matches your vehicle before ordering.
Installing a Ford oil filter yourself
If you change your own oil, installing the filter takes about five minutes. Locate the filter canister (usually on the side or top of the engine), use an oil filter wrench to unscrew the old filter, and hand-tighten the new one until the rubber gasket on top makes contact with the engine block. Then turn it an additional three-quarter turn by hand — do not use the wrench to tighten it further, because over-tightening can damage the gasket and cause leaks.
Before you install the new filter, fill it about three-quarters full with fresh oil from the can you are using for the oil change. This primes the filter so it does not starve the engine of oil during the first few seconds after you start the engine. After you finish the oil change, start the engine and let it run for a minute, then check the oil level and top it off if needed.
Frequently Asked Questions
Can I use any oil filter on my Ford, or does it have to be a Motorcraft?
You can use any filter that matches your Ford's part number and meets Ford's specifications. Motorcraft is the official brand, but aftermarket filters from Fram, Purolator, and others work well if they have the same micron rating and bypass pressure. Always verify the part number before buying.
What happens if I use the wrong oil filter on my Ford?
Using the wrong filter can restrict oil flow to your engine or allow unfiltered oil to circulate if the bypass valve pressure does not match. Either situation can lead to engine wear over time. Always match the part number to your specific model year and engine size.
How long does a Ford oil filter last?
A Ford oil filter lasts until your next oil change, which is typically 10,000 miles or one year for most models. Some newer Fords with synthetic oil can go 15,000 miles between changes. Replace the filter every time you change the oil, even if it looks clean.
Is it cheaper to buy a Motorcraft filter or an aftermarket filter?
Aftermarket filters usually cost less than Motorcraft filters — sometimes by $5 to $10 per filter. Over the life of your Ford, the savings add up, but the difference is small enough that many owners choose Motorcraft for the warranty and peace of mind.
Where is the oil filter located on a Ford?
The location varies by model. On most Fords, the filter is on the side or top of the engine block. Check your owner's manual for the exact location, or ask a parts counter — they can show you a diagram for your specific model year.
