How to Change Your Nissan Altima's Oil Filter: A Complete Step-by-Step Guide

What You'll Need Before You Start

Changing your Nissan Altima's oil filter is a task you can do at home with basic tools. Before you begin, gather these items:

• A new oil filter (the correct size for your Altima model year)
• An oil filter wrench
• A drain pan or container
• Clean rags or paper towels
• Jack and jack stands (if needed for under-car access)
• Safety glasses
• Work gloves
• Fresh motor oil (if you're also changing the oil)

Check your owner's manual to find the exact filter size and location for your specific model year. Different Altima generations may have the filter in different spots, so knowing your model year helps you work faster and avoid confusion.

Prepare Your Vehicle

Start by warming up your engine for a few minutes. This helps the oil flow more easily and makes the old filter easier to remove. Then turn off the engine and let it cool for a few minutes—you want the oil warm but not hot enough to burn your hands.

Park on a level surface and engage the parking brake. Make sure the engine is cool enough to touch safely. If you need to raise your vehicle to reach the filter, use a jack and secure jack stands before working underneath. Never rely only on a jack—it can slip, and jack stands keep you safe.

Wear your safety glasses throughout this process. Even though you're working on an oil filter, small debris or oil spray can get in your eyes.

Locate and Remove the Old Filter

Find the oil filter on your Altima. Its location varies by model year, but your owner's manual shows exactly where it is. On many Altima models, the filter is located on the side of the engine block, but some years place it underneath or toward the back of the engine bay.

Place your drain pan underneath the filter to catch any oil that spills. This prevents oil from draining onto your driveway or garage floor.

Use your oil filter wrench to turn the filter counterclockwise until it comes loose. Once it's loose enough, finish unscrewing it by hand. Be careful—there will be oil inside the filter, and it may still be warm. Tilt the filter as you remove it to keep oil from pouring out of the opening.

Wipe the filter mounting surface clean with a rag. Remove any old rubber gasket material or debris. This is important because a clean surface helps the new filter seal properly and prevents leaks.

Install the New Filter

Take your new filter and apply a thin layer of fresh oil to the rubber gasket on top of the filter. This creates a better seal and makes it easier to remove the filter next time you change it.

Screw the new filter onto the mounting surface by hand. Once the gasket makes contact with the mounting surface, turn the filter an additional three-quarter turn. Do not use the wrench to tighten it—hand-tight is the correct level of tightness. Over-tightening can damage the filter and make it hard to remove later.

Double-check that the filter is seated properly and not crooked. A crooked filter can leak.

Check Your Work

Start your engine and let it run for a minute. This pressurizes the oil system and helps the new filter seal properly. Check underneath your vehicle and around the filter for any leaks. If you see dripping oil, turn off the engine and tighten the filter slightly more—usually just a quarter turn is enough.

Turn off the engine and wait a few minutes for the oil to settle. Check your oil level using the dipstick and add oil if needed to reach the full mark. This is especially important if you drained oil during this process.

Dispose of the Old Filter Properly

The old filter contains used oil and should not go in the trash. Take it to an auto parts store, recycling center, or service station that accepts used oil filters. Many accept them for free or for a small fee.

If you drained oil during this process, store it in a sealed container and take it to the same locations for proper disposal. Used oil can harm the environment, so proper disposal matters.

Key Takeaways

• Warm your engine before starting, but let it cool slightly so you don't burn yourself
• Always use a drain pan to catch spilled oil
• Clean the filter mounting surface before installing the new filter
• Apply a thin layer of fresh oil to the new filter's gasket
• Hand-tighten the filter only—do not use a wrench to tighten it
• Run the engine briefly and check for leaks
• Dispose of the old filter and any drained oil at a proper recycling location

Frequently Asked Questions

How often should I change my Nissan Altima's oil filter?

Most Nissan Altimas need an oil filter change every 3,000 to 5,000 miles, though some newer models can go longer. Check your owner's manual for the recommended interval for your specific model year and driving conditions. If you do a lot of short trips or towing, you may need to change it more often.

Can I change the oil filter without changing the oil?

Yes, you can change just the oil filter without draining and replacing all the oil. However, many people change both at the same time since you're already under the vehicle. If you only change the filter, you'll still need to check your oil level afterward to make sure it's at the full mark.

What should I do if the old filter is stuck and won't come loose?

If the filter is very tight, try wrapping a rubber band or old cloth around it to give your wrench better grip. You can also try tapping the wrench gently with a hammer to help break the seal. If it's still stuck, apply penetrating oil around the base of the filter and wait 15 minutes before trying again. Never use excessive force, as you could damage the filter housing.

Is it normal for oil to drip after I install the new filter?

A drop or two is normal, but steady dripping means the filter isn't sealed properly. Turn off the engine, wait a few minutes, and tighten the filter another quarter turn. Then run the engine again and check for leaks. If it still leaks, remove the filter and check that the rubber gasket is in place and the mounting surface is clean.
