The correct oil filter for your 2013 F-150 5.0 is the Motorcraft FL-910S or an equivalent filter rated for 5.0L engines

Ford's 5.0-liter V8 engine in the 2013 F-150 uses a spin-on oil filter that threads directly onto the engine block. The OEM (original equipment manufacturer) part number is FL-910S, made by Motorcraft, Ford's parts division. This filter is designed specifically for the flow rate, bypass valve pressure, and thread size that the 5.0L requires.

If you choose an aftermarket filter instead of Motorcraft, look for one rated for the 5.0L engine and verify the thread size is 3/4-16 UNF (the standard for this engine). Many common brands like Fram, Purolator, and Bosch make compatible filters, but the part number and specifications matter more than the brand name.

Key Takeaways

  • The OEM filter for a 2013 F-150 5.0L is the Motorcraft FL-910S, which you can find at Ford dealerships or online retailers.
  • Aftermarket filters work if they are rated for the 5.0L engine and have the correct 3/4-16 UNF thread size.
  • The filter location on the 5.0L is on the driver's side of the engine block, accessible from above without removing the wheel.
  • Oil filter changes should happen at the interval specified in your owner's manual, typically every 5,000 to 10,000 miles depending on driving conditions.

Where the filter sits and how to access it

On the 2013 F-150 5.0L, the oil filter mounts vertically on the driver's side of the engine block, below the intake manifold. You can reach it from the top of the engine bay without lifting the truck or removing wheels. The filter head sits roughly 8 to 10 inches below the top of the engine.

Before you start, let the engine cool for at least 5 to 10 minutes after running. Hot oil drains faster but can cause burns. Position a drain pan underneath the filter — oil will spill when you unscrew it. A filter wrench (a band-type or socket-type wrench that grips the filter body) makes removal easier, though you can unscrew it by hand if you have a good grip and the filter is not over-tightened.

Thread size and filter compatibility

The 2013 F-150 5.0L uses a 3/4-16 UNF thread, which is the most common thread size for Ford trucks and many other vehicles. When you buy a replacement filter, the packaging or product listing should state the thread size. If it does not, call the retailer or check the manufacturer's website before purchasing.

Using the wrong thread size can result in leaks, improper seating, or damage to the engine block threads. The FL-910S and its equivalents are all 3/4-16 UNF. If you are unsure whether an aftermarket filter matches your engine, cross-reference the part number on Ford's parts catalog or ask the retailer to confirm compatibility with the 2013 F-150 5.0L.

Motorcraft versus aftermarket filters

Motorcraft FL-910S filters meet Ford's original specifications for flow rate, bypass valve opening pressure, and media quality. They cost between $8 and $15 depending on where you buy them. Aftermarket filters from established brands typically cost $5 to $12 and perform similarly if they carry the same specifications.

The main difference is consistency. Motorcraft filters are made to the same standard every time because Ford controls the manufacturing. Aftermarket filters vary slightly by brand and sometimes by production batch. For routine maintenance, either works; for peace of mind or if your truck has high mileage, Motorcraft is the safer choice.

Oil capacity and filter change intervals

The 2013 F-150 5.0L holds approximately 6 quarts of oil when you change the filter and drain the pan. Your owner's manual specifies the exact capacity and the recommended change interval — typically 5,000 miles for severe driving conditions (towing, idling, dusty environments) or 10,000 miles for normal highway driving.

Always check your manual for the interval that matches your driving. Using synthetic oil may allow longer intervals, but the filter should still be changed at the same time as the oil. Skipping filter changes or extending them beyond the recommended interval can reduce oil flow and increase engine wear.

Installation steps and torque specifications

After draining the old oil, clean the filter mounting surface on the engine block with a rag to remove any debris or old gasket material. explore a thin layer of new oil to the rubber gasket on the new filter — this helps create a proper seal and makes removal easier next time. Screw the filter on by hand until the gasket contacts the mounting surface, then turn it an additional three-quarter turn (roughly 270 degrees).

Do not use a wrench to tighten the filter. Hand-tight is correct. Over-tightening crushes the gasket, causes leaks, and makes the filter nearly impossible to remove next time. After installation, run the engine for 30 seconds, shut it off, wait a minute, and check the filter for leaks around the gasket. If you see oil seeping, turn the filter another quarter turn and recheck.

Where to buy the FL-910S or equivalent

Ford dealerships stock the Motorcraft FL-910S year-round and can order it same-day if they do not have it in stock. Online retailers like RockAuto, Amazon, and eBay carry both Motorcraft and aftermarket options, often at lower prices than dealerships. Auto parts stores like AutoZone, O'Reilly, and NAPA stock multiple compatible filters and can tell you when ready if they have the part in stock.

Prices vary by retailer and whether you choose OEM or aftermarket. Motorcraft typically runs $10 to $15 at dealerships and $8 to $12 online. Aftermarket filters run $5 to $10. Shipping time matters if you need the filter today — local pickup from an auto parts store is fastest, while online orders may take 2 to 5 business days.

Frequently Asked Questions

Can I use a different Motorcraft filter number if I cannot find the FL-910S?

No. The FL-910S is the only Motorcraft filter designed for the 5.0L in the 2013 F-150. Other Motorcraft numbers are for different engines or truck models and may not fit or may have the wrong bypass pressure. Always use the FL-910S or an aftermarket filter specifically rated for the 5.0L.

What happens if I over-tighten the oil filter?

Over-tightening crushes the rubber gasket and can cause leaks when ready or within a few days as the gasket deteriorates. It also makes removal difficult — you may need a wrench or filter cutter to remove it next time, risking damage to the mounting surface. Hand-tight plus three-quarter turn is the correct torque.

Is synthetic oil compatible with the FL-910S filter?

Yes. The FL-910S works with conventional, synthetic blend, and full synthetic oils. The filter itself does not change based on oil type. However, synthetic oil may allow longer change intervals — check your owner's manual for the recommended interval when using synthetic.

How do I know if my filter is leaking after installation?

Run the engine for 30 seconds, shut it off, and wait one minute for the oil to settle. Look at the base of the filter where it threads onto the engine block. If you see oil dripping or seeping around the gasket, the filter is not seated properly. Turn it another quarter turn and recheck.

Can I change the oil filter without draining the oil?

Yes. You can change the filter alone between full oil changes, though most people do both at the same time. If you change only the filter, expect a small amount of oil to spill — have a drain pan ready. The filter change interval is the same as the oil change interval, so changing one without the other is not typical maintenance.
