Nissan Altima Oil Filter Size

So, you're wrestling with an oil change on your Nissan Altima and have hit a snag – the dreaded oil filter size dilemma. I get it. It's a common issue, and thankfully, it's usually a pretty straightforward fix. As a service advisor for over 15 years, I've seen this question pop up countless times. This guide will walk you through everything you need to know about Altima oil filters, ensuring you get the right one and avoid any headaches.

The Problem: Which Oil Filter Fits My Altima?

The seemingly simple question of "what oil filter does my Nissan Altima use?" can quickly become complicated. Here's why:

Model Year Variations: Nissan has used different engines in the Altima over the years. A 2002 Altima 2.5L will almost certainly use a different filter than a 2018 Altima 3.5L.
Engine Size Matters: Even within the same model year, the engine size (e.g., 2.5L 4-cylinder vs. 3.5L V6) dictates the filter.
Aftermarket vs. OEM: While aftermarket filters can be perfectly acceptable (and often more affordable), their sizing and thread pitch *must* match the original equipment manufacturer (OEM) specifications to prevent leaks or damage.
Previous Owner Interference: Unfortunately, sometimes a previous owner or even a less-than-diligent mechanic may have installed the wrong filter in the past. You'll need to identify the correct fitment, regardless of what's currently installed.

Using the wrong oil filter can lead to several problems:

Oil Leaks: Incorrect threading or improper sealing can cause oil to leak, leading to low oil pressure and potential engine damage.
Reduced Oil Pressure: A filter that's too restrictive can starve the engine of oil, causing wear and tear.
Filter Damage: An ill-fitting filter may not withstand the engine's oil pressure and could rupture, causing catastrophic engine failure.

The Solution: Identifying the Correct Oil Filter

Okay, let's get down to brass tacks. Here's how to make sure you're using the right oil filter:

Step 1: Consult Your Owner's Manual

This is always the best starting point. Your owner's manual should specify the correct oil filter part number for your specific Altima model and engine. Look for a section on "Engine Oil" or "Maintenance." Refer to this first before purchasing anything.

Step 2: Use Online Parts Finders

Major auto parts retailers like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts have online tools that allow you to search for parts by year, make, and model. Simply enter your Altima's information, and the tool will display a list of compatible oil filters. Make sure to double-check that the engine size is also specified in the search results. Most websites also let you enter your VIN for even more accurate results.

Step 3: Cross-Reference with a Reputable Filter Brand

Once you have a potential part number from your owner's manual or an online parts finder, cross-reference it with a reputable filter brand like:

Nissan (OEM): The safest bet for guaranteed compatibility.
Mobil 1: Known for high-quality filtration.
K&N: Often preferred for performance applications (though not always necessary for daily driving).
Purolator: A reliable and affordable option.
Fram: Another widely available and budget-friendly choice.

Each of these brands has online catalogs or cross-reference tools that will confirm compatibility based on the OEM part number. For example, if your owner's manual specifies a Nissan part number of "15208-9F60A," you can use the Mobil 1 website to find the corresponding Mobil 1 filter (e.g., M1-104).

Step 4: Verify the Dimensions and Thread Pitch

This is crucial, especially if you're using an aftermarket filter. The oil filter *must* have the same dimensions (diameter, height) and thread pitch as the original. You can usually find this information on the filter's packaging or the manufacturer's website. Do not force a filter on if it doesn't thread on smoothly.

Step 5: When in Doubt, Ask a Professional

If you're still unsure, don't hesitate to ask a qualified mechanic or auto parts store employee. They can use their expertise and resources to help you identify the correct oil filter for your Altima.

Specific Altima Oil Filter Examples

While you *always* need to verify the correct filter for your specific vehicle, here are some common examples to give you a general idea:

2002-2006 Nissan Altima (2.5L 4-Cylinder): Often uses a filter with part number equivalents such as Nissan 15208-9F60A, Mobil 1 M1-104, or Fram PH7317.
2007-2012 Nissan Altima (2.5L 4-Cylinder): May use a filter with part number equivalents such as Nissan 15208-9F60A, Mobil 1 M1-104, or Fram PH7317. *However, verify with your manual.*
2007-2012 Nissan Altima (3.5L V6): Typically uses a different filter than the 4-cylinder model. Common equivalents include Nissan 15208-31U00, Mobil 1 M1-110, or Fram PH3614.
2013-2018 Nissan Altima (2.5L 4-Cylinder): Commonly uses Nissan part number 15208-65F0E, Mobil 1 M1-110A, or Fram PH7317.
2013-2018 Nissan Altima (3.5L V6): Will likely take Nissan part number 15208-65F0E, Mobil 1 M1-110A, or Fram PH7317.
2019+ Nissan Altima (2.5L 4-Cylinder): Varies; consult your manual or a parts finder.

Important Note: These are just examples! Always, always, always verify the correct filter for your specific Altima using the methods outlined above.

Tools and Supplies Needed for an Oil Change

Performing an oil change on your Altima is generally a DIY-friendly task. Here's what you'll need:

The Correct Oil Filter: As discussed above!
The Correct Engine Oil: Check your owner's manual for the recommended oil type and viscosity (e.g., 5W-30 synthetic).
Oil Filter Wrench: To remove the old filter. Sizes vary, so make sure you have one that fits your filter.
Socket Set or Wrench: To remove the oil drain plug. The size will depend on your Altima's model year.
Oil Drain Pan: To catch the used oil.
Funnel: To pour the new oil into the engine.
Gloves: To protect your hands.
Rags or Shop Towels: For cleaning up spills.
Jack and Jack Stands (Optional): To lift the vehicle for easier access to the drain plug and filter. Always use jack stands for safety!
Wheel Chocks (Optional): For added safety.

Approximate Cost of an Oil Change

The cost of an oil change can vary depending on whether you do it yourself or take it to a shop:

DIY Oil Change: The cost of the oil and filter will typically range from $30 to $75, depending on the type of oil you use (conventional, synthetic blend, or full synthetic) and the quality of the filter.
Professional Oil Change: A professional oil change at a shop or dealership can cost anywhere from $50 to $150 or more, depending on the type of oil used and the shop's labor rates. Synthetic oil changes will generally be more expensive.

Additional Tips and Considerations

Pre-Lube the Filter: Before installing the new oil filter, lightly coat the rubber gasket with fresh engine oil. This will help create a better seal and prevent leaks.
Tighten to Spec: Don't overtighten the oil filter. Follow the instructions on the filter or in your owner's manual for the proper torque specification. Usually, it's hand-tightened plus a certain fraction of a turn.
Dispose of Used Oil Properly: Take your used oil to a recycling center or auto parts store for proper disposal.
Check the Oil Level: After completing the oil change, run the engine for a few minutes and then check the oil level using the dipstick. Add more oil if necessary to reach the "full" mark.
Inspect for Leaks: After the oil change, inspect the drain plug and oil filter for any leaks.
Keep Records: Keep a record of your oil changes, including the date, mileage, and type of oil and filter used. This will help you maintain your Altima's engine properly.
Consider Oil Analysis: For older or high-mileage Altimas, consider getting an oil analysis done periodically. This can provide valuable insights into the health of your engine.

By following these steps, you can confidently select the correct oil filter for your Nissan Altima and perform a successful oil change. Remember to prioritize safety and always double-check your work. Happy motoring!
