Which oil filter fits your F-150 depends on the engine size and model year
Ford F-150 trucks use different oil filters depending on whether you have a 3.5L EcoBoost, 5.0L V8, 3.3L V6, or another engine variant. The filter size, thread pitch, and bypass valve rating all vary by engine. Your owner's manual lists the exact part number, but you can also identify the right filter by engine type and year — and most auto parts stores can cross-reference your VIN to confirm the match before you buy.
Using the wrong filter can mean inadequate oil flow, reduced engine protection, or a filter that does not seal properly. The cost difference between filters is usually $5 to $15, so buying the correct one the first time saves time and prevents damage.
Key Takeaways
- Ford F-150 oil filters vary by engine size and model year, so checking your owner's manual or VIN is the most reliable way to find the right part number.
- Common F-150 filters include the Motorcraft FL-2051S (many gasoline engines) and FL-500S (some EcoBoost models), but your specific engine may use a different filter.
- OEM Motorcraft filters, Fram, Bosch, and Mobil 1 are all widely available replacements that meet Ford specifications.
- The filter wrench size and thread pitch matter when you install it, so confirm these details before you start the job.
How to identify your F-150 engine and find the matching filter
Start by locating your Vehicle Identification Number (VIN) on the driver's side dashboard or door jamb. The 10th character in the VIN identifies the engine code. Write down that code and your model year, then open your owner's manual to the maintenance section — it will list the correct oil filter part number for your specific engine.
If you do not have the manual, visit a Ford dealership parts counter or an auto parts store (AutoZone, O'Reilly, NAPA, Advance Auto Parts) with your VIN. They will cross-reference it in their system and tell you the exact filter you need. Many stores will also check the filter size and thread pitch so you know what wrench to use during installation.
You can also search online using your VIN and the year, make, and model — Ford's official parts catalog and third-party sites like RockAuto and Amazon will show compatible filters and their specifications.
Common F-150 oil filter part numbers by engine type
The Motorcraft FL-2051S is one of the most common filters for F-150 gasoline engines, including many 5.0L V8 and 3.3L V6 models. It has a 3/4-inch-16 thread and a 65 PSI bypass valve. The Motorcraft FL-500S fits some 3.5L EcoBoost engines and has a 3/4-inch-16 thread as well.
Newer F-150 models (2018 and later) with the 3.5L EcoBoost may use the Motorcraft FL-2016S instead. Always verify the part number in your manual or with a parts counter before ordering, because using the wrong filter can affect oil pressure and engine wear.
| Engine Type | Common Filter Part Number | Thread Size | Bypass Valve PSI |
|---|---|---|---|
| 5.0L V8 | Motorcraft FL-2051S | 3/4-inch-16 | 65 PSI |
| 3.5L EcoBoost (older) | Motorcraft FL-500S | 3/4-inch-16 | 65 PSI |
| 3.5L EcoBoost (2018+) | Motorcraft FL-2016S | 3/4-inch-16 | 65 PSI |
| 3.3L V6 | Motorcraft FL-2051S | 3/4-inch-16 | 65 PSI |
This table covers the most common F-150 engines, but your truck may use a different filter. Check your manual or VIN to confirm before you buy.
OEM versus aftermarket filters for F-150 trucks
OEM (Original Equipment Manufacturer) filters are made by Motorcraft, Ford's parts division, and are engineered to Ford's exact specifications. They cost $8 to $15 per filter and are available at Ford dealerships and most auto parts stores. OEM filters carry a warranty and are may provide to fit and perform correctly.
Aftermarket filters from brands like Fram, Bosch, Mobil 1, and Purolator also meet Ford specifications and are often cheaper — typically $5 to $12. Many truck owners use aftermarket filters without issues, but quality varies by brand. Fram and Bosch are widely trusted, while some budget brands may have lower bypass valve ratings or thinner filter media.
If you plan to keep your F-150 long-term or drive in dusty conditions, OEM or premium aftermarket filters (Mobil 1, Bosch) are worth the extra cost. For routine maintenance on a newer truck, a mid-range aftermarket filter works fine as long as it matches your engine's specifications.
Filter wrench size and installation considerations
Most F-150 oil filters use a 3/4-inch-16 thread, which means you need a filter wrench that fits a 3/4-inch diameter. Common wrench sizes for F-150 filters are 74 mm (about 2.9 inches) or 86 mm (about 3.4 inches). Check the filter canister or your manual to confirm the exact size before you buy a wrench.
When you install the filter, hand-tighten it until the rubber gasket touches the engine block, then turn it an additional 3/4 turn. Over-tightening can damage the gasket and make the filter hard to remove next time. Under-tightening can cause leaks or the filter to spin off during operation.
Some F-150 models have the filter mounted vertically (top of engine) and others horizontally (side of engine block). The location affects how much oil drains when you remove the old filter — expect 1 to 2 quarts to spill, so place a drain pan underneath before you start.
Where to buy F-150 oil filters and what to expect
Ford dealerships stock OEM Motorcraft filters and can order any part number within 24 hours. Prices are typically higher than auto parts stores, but you get a warranty and the certainty that the part is correct.
Auto parts chains (AutoZone, O'Reilly, NAPA, Advance Auto Parts) carry both OEM and aftermarket filters in stock. Most offer free installation if you buy the filter from them, and they can cross-reference your VIN to confirm the right part before you leave the store. Prices are usually 20 to 30 percent lower than dealerships.
Online retailers like Amazon, RockAuto, and Walmart sell filters at competitive prices, but you pay for shipping and have to wait for delivery. If you need the filter today, a local auto parts store is faster. If you are planning ahead, online ordering saves money.
Frequently Asked Questions
Can I use a different oil filter if the exact part number is not available?
Only if the replacement has the same thread size (usually 3/4-inch-16 for F-150s), the same bypass valve rating (usually 65 PSI), and the same or larger filter media surface area. Do not substitute a filter with a lower bypass valve rating, because it may open too early and allow unfiltered oil to circulate. Call an auto parts store or dealership to confirm compatibility before you install a different filter.
How often should I change my F-150 oil filter?
Ford recommends changing the oil filter every time you change the oil. For most F-150 trucks, that is every 5,000 to 10,000 miles, depending on your engine and driving conditions. Check your owner's manual for the exact interval for your model year and engine type.
What does the bypass valve in an oil filter do?
The bypass valve opens if the filter becomes clogged or if the oil is too thick (in cold weather), allowing unfiltered oil to flow to the engine rather than starving it of oil. A 65 PSI bypass valve is standard for most F-150 engines and opens when pressure exceeds that threshold. Using a filter with the wrong bypass rating can affect engine protection.
Is it worth buying a premium oil filter for my F-150?
Premium filters (Mobil 1, Bosch) have thicker media and better dirt-holding capacity, so they last longer and protect the engine better in dusty or high-mileage conditions. For routine maintenance on a newer truck with regular oil changes, a standard OEM or mid-range aftermarket filter is sufficient. If you tow, drive in dusty terrain, or have over 100,000 miles, a premium filter is a worthwhile investment.
