The oil filter you need depends on the engine in your 2010 Ford Fusion: the 2.5L four-cylinder uses Motorcraft FL-820S, while the 3.0L V6 uses Motorcraft FL-910S. If you’re unsure which engine your car has, check the VIN or the engine badge under the hood.
Engine options and filter mapping
In the United States, the 2010 Fusion offered two common engines. The correct filter is tied to the engine, so identify which powerplant sits under your hood to select the right part.
- 2.5L Duratec I-4 (engine code typically 2.5): Motorcraft FL-820S oil filter.
- 3.0L Duratec V6 (engine code typically 3.0): Motorcraft FL-910S oil filter.
Knowing your engine makes ordering easier, and using the OEM part ensures proper fit and filtration. If you substitute brands, verify that the alternative part matches the same size, thread pitch, and gasket dimensions as the Motorcraft numbers above.
How to confirm the right filter for your car
Use these steps to ensure you buy the correct filter for your specific Fusion configuration:
- Identify the engine by checking the engine stamp on the valve cover or the owner’s manual.
- Locate the VIN and use Ford’s parts lookup or a trusted parts retailer to confirm the engine option associated with your VIN.
- Compare the OEM filter part numbers (FL-820S or FL-910S) to the filter currently installed if you’re replacing an old unit.
- Purchase the filter from a reputable retailer, ensuring the exact fit for your engine to avoid leaks or improper filtration.
- If in doubt, consult a Ford dealership or a qualified mechanic with your VIN ready for a definitive match.
Concluding that careful verification upfront helps prevent incorrect purchases and ensures your engine remains properly lubricated and protected.
OEM vs aftermarket: brands that fit
Motorcraft is the OEM recommendation for Ford vehicles, but established aftermarket brands also offer compatible filters. When shopping, cross-reference the product with the corresponding OEM numbers (FL-820S for the 2.5L and FL-910S for the 3.0L) to ensure fit and performance.
- Motorcraft (OEM) — FL-820S (2.5L) or FL-910S (3.0L)
- Wix
- Bosch
- Fram
- Purolator
Always verify fitment with your engine and vehicle VIN, since some aftermarket filters can vary in size or gasket design even when they advertise compatibility.
Summary
The 2010 Ford Fusion requires an oil filter matched to its engine: FL-820S for the 2.5L I-4 and FL-910S for the 3.0L V6. Confirm your engine via VIN or engine badge, and then purchase the proper filter from Motorcraft or a trusted aftermarket brand that Cross-references to the OEM numbers. Proper identification and fitment help ensure effective oil filtration and engine protection.
