The 2014 Buick Enclave uses a 3.6-liter V6 engine, and the OEM oil filter commonly recommended is the AC Delco GM OE PF2252 (or an equivalent GM-approved filter). Always verify compatibility with your VIN or engine code before purchase.
Because Buick offered two 3.6L V6 configurations in that model year, the exact filter can vary by engine variant. Checking your engine code or VIN helps ensure you select the correct part for your vehicle.
Engine options in the 2014 Enclave
In 2014, the Enclave relied on a 3.6L V6 that could be configured in slightly different variants across production runs. The two commonly encountered configurations are the LLT and the LFX variants. While the basic oil-filter function remains the same, the precise GM part number can differ between these engine codes. Confirming the exact engine code ensures you order the correct filter.
3.6L LLT
The LLT-based 3.6L V6 is part of GM’s earlier 3.6L family. For many LLT-equipped vehicles, GM/ACDelco’s PF2252 or an equivalent filter is used. When your vehicle’s data plate or service documentation lists LLT, this is the most frequently referenced filter option.
3.6L LFX
The LFX version is the direct-injection variant used in later GM applications. Vehicles with the LFX configuration may use a different but compatible GM/ACDelco filter number than the LLT, so verifying via VIN or parts catalog is advised to confirm the exact part number.
How to confirm the right filter for your Enclave
To avoid ordering the wrong part, use these steps to identify and confirm the correct oil filter for your 2014 Enclave:
- Identify the engine code (LLT or LFX) by checking the under-hood label near the radiator or by decoding the VIN.
- Consult the owner’s manual or the GM/ACDelco parts catalog for the exact GM part number that matches your engine code and model year.
- Compare the physical filter on your vehicle with reference images or specifications to ensure the thread size and mounting orientation are compatible.
- When in doubt, ask a dealer or skilled auto parts professional and provide your VIN for precise cross-referencing.
Using the correct filter number recommended for your engine code helps maintain proper oil pressure and filtration, which supports engine longevity and performance. If you are replacing the filter yourself, a high-quality aftermarket filter that meets or exceeds GM’s specs can be a suitable alternative, provided it matches the engine code and thread configuration.
Summary
For a 2014 Buick Enclave, the typical GM OE oil filter used with the 3.6L V6 is PF2252 or its equivalent, though exact part numbers can differ between LLT and LFX engine variants. Always verify the correct filter using your VIN or engine code, and consult GM’s parts catalog or a dealership for precise compatibility. Regular maintenance with the proper filter ensures optimal oil flow and engine protection.
