The 2016 Buick Enclave with the 3.6-liter V6 uses a standard spin-on oil filter. You can replace it with GM OEM/AC Delco filters or reputable aftermarket equivalents, such as the AC Delco PF63 cross-reference for 3.6L GM engines.
In detail, the Enclave’s 2016 model year is equipped with GM’s 3.6L V6 (LFX family) that typically uses a spin-on oil filter rather than a cartridge in a housing. To ensure you choose the correct unit, verify the part number on your current filter or check your VIN at a parts counter. The guide below reviews the filter type, how to identify the correct filter, and reliable replacement options.
Filter type and identification
Here is how to confirm you’re selecting the right filter for your Enclave:
- Confirm that your engine is the 3.6L V6 (LFX) and that your model year is 2016; this combination uses a spin-on filter in most markets.
- Check the current oil filter for its part number; this can be used to cross-reference with aftermarket options.
- If you’re unsure, consult the owner's manual or a Buick/GM dealer to verify compatibility with your VIN.
By following these steps, you can be confident you’re buying the correct spin-on filter for your Enclave.
Common replacement options
Multiple reputable brands supply cross-reference options that fit the 3.6L GM engines used in the 2016 Enclave. The list below covers widely available choices; always confirm cross-reference to your VIN or current filter.
- AC Delco (GM Genuine Parts) – widely used as OEM replacement; look for the PF63 cross-reference for 3.6L engines.

When selecting a replacement, ensure the filter is rated for your oil specification and viscosity (often 0W-20 synthetic for modern GM 3.6Ls) and that the thread size and gasket are compatible with the Enclave’s filter housing.
Replacement quick guide
For a quick DIY replacement, follow these general steps. Always consult a service manual for torque specs and procedures specific to your vehicle.
- Warm up the engine, then park on a level surface and apply the parking brake.
- Drain the engine oil into a pan by removing the drain plug; replace the drain plug gasket if needed.
- Remove the old oil filter with an oil filter wrench; have a pan underneath to catch any remaining oil.
- Install the new filter by hand until snug, then tighten per manufacturer instructions (usually 3/4 to 1 turn after gasket contact).
- Refill with the recommended oil, check for leaks, and reset the oil-life monitor as needed.
Note: If you’re not comfortable performing an oil change, a professional technician can complete the task quickly and correctly.
Summary
The 2016 Buick Enclave uses a standard spin-on oil filter for its 3.6L V6 engine.
