For the common 2012 Ford Focus with the 2.0-liter gasoline engine, the typical OEM oil filter is Motorcraft. In many regions this is the Motorcraft FL910S, though the exact part number can vary by engine variant and market. Always verify with your VIN or the owner's manual to be certain.
The following guide helps you identify the correct oil filter for your specific Focus, explains why the engine variant matters, and shows how to confirm the exact part number before purchase.
Identify your engine and market
The 2012 Focus was offered with several engines across different regions, including a 2.0L Duratec I4 in many markets and diesel variants like the 1.6L Duratorq TDCi in others. Because Ford uses different filter housings and part numbers for these engines, the exact filter you need depends on your engine family and where the car was sold. Start by confirming your engine code and regional spec, which you can find in the owner’s manual or on the vehicle’s identification plates.
Common OEM option for the 2.0L Duratec I4
For many 2012 Focus models with the 2.0L Duratec I4, Ford’s Motorcraft oil filter is the recommended choice. The most frequently cited part number for this engine in several regions is FL910S, with aftermarket cross-references available from other brands. Your exact number may differ if your car uses a different engine variant or is from a different market.
- Motorcraft FL910S
- Equivalent aftermarket options (cross-referenced by your parts supplier) from brands such as Wix, Bosch, and Mann, provided they match the same thread size and gasket/diameter
Note: The list above covers the most common options for the 2.0L Duratec AIO family in many markets. Your precise part number may differ based on the engine code and region. Always verify via VIN-based parts lookup or the official maintenance guide before ordering.
How to verify you have the right filter
To ensure you obtain the correct filter, use one of these verification methods: read the part number printed on the filter you currently have, check Ford’s official parts lookup with your VIN, or consult your owner’s manual for the exact specification. When in doubt, provide your engine code and market to a reputable parts counter so they can pull the exact match.
Once you confirm the correct filter, you can purchase a Motorcraft filter or a reputable aftermarket equivalent. Remember to replace the O-ring and lightly oil the gasket before installation, and to follow the manufacturer’s oil-change interval for your driving conditions.
Where to buy and installation tips
Motorcraft filters are widely stocked at Ford dealers and major parts retailers, and many reputable aftermarket brands offer cross-referenced equivalents. When installing, ensure you torque to the manufacturer’s specification and avoid overtightening. It’s also a good practice to replace the oil drain gasket if your service procedure includes it and to use the recommended grade and viscosity of oil for your engine.
Always follow the official maintenance schedule for your 2012 Focus and adjust for driving conditions (city vs. highway, extreme temperatures, and frequent short trips can shorten oil-change intervals).
Summary
In short, the 2012 Ford Focus’s oil filter depends on the engine variant and market, with Motorcraft FL910S being the typical OEM choice for the common 2.0L Duratec I4 in many regions. To ensure you get the exact part, verify your engine code and market via VIN or the owner’s manual before purchasing. This approach helps ensure proper fit, thread size, and gasket compatibility for optimal oil filtration and engine protection.
