The 2010 Nissan Altima uses a standard 3/4-16 UNF threaded oil filter. The exact filter model depends on which engine your car has (2.5L four-cylinder or 3.5L V6), but both share the same thread size. Confirm the exact part by checking your current filter or your vehicle’s engine code.
Engine options and filter thread size
The Altima offered two engines in 2010. Here is a quick reference to the common thread size you’ll encounter with both, so you can replace the filter without guessing.
- 2.5L QR25DE four-cylinder: 3/4-16 UNF threaded oil filter; compatible with standard aftermarket replacements designed for this thread.
- 3.5L VQ35DE V6: 3/4-16 UNF threaded oil filter; compatible with standard aftermarket replacements designed for this thread.
Bottom line: The threading is the same (3/4-16 UNF) for the two 2010 Altima engines, so you can shop by thread size and engine compatibility when selecting a replacement.
How to identify the exact filter model for your Altima
To ensure you get the exact OEM or aftermarket filter for your specific car, use these steps.
- Inspect your current oil filter for part numbers or brand markings to guide your replacement choice.
- Consult the owner’s manual or service manual for the recommended filter part number for your engine (2.5L or 3.5L).
- Provide your VIN or engine code to a Nissan dealer or parts retailer so they can look up the precise filter model for your car.
Following these steps helps you avoid mismatches and ensures a proper seal and fit.
What to buy and installation tips
When shopping for a replacement and preparing for the change, keep these guidelines in mind so you pick the right filter and install it correctly.
- Choose a filter designed for 3/4-16 UNF threads and compatible with your engine (2.5L or 3.5L).
- Match the oil specification for your Altima (often 5W-30) and replace the drain plug washer as needed.
- Install the new filter by hand until seated, then give it a final snug turn per the manufacturer’s torque spec; avoid overtightening.
These practices help ensure a reliable seal, proper oil flow, and long-term engine protection.
Summary: For a 2010 Nissan Altima, the oil filter uses a 3/4-16 UNF thread. Engine choice (2.5L or 3.5L) determines the exact filter model, but the thread size remains the same. Verify part numbers with your current filter, manual, or a parts professional to ensure a precise match.
