Nov 13, 2025 by Alex Braham 40 views

Hey guys! Changing your oil is one of the most important things you can do to keep your car running smoothly. If you've got a 2018 Nissan Altima SR, this guide is perfect for you. We'll walk you through everything you need to know to do an oil change yourself. Doing it yourself can save you money and help you learn more about your car.

Why Regular Oil Changes Are Important

Oil changes are super important for your car's health. The engine oil lubricates all the moving parts in your engine, reducing friction and preventing wear. Over time, this oil gets dirty and breaks down, losing its ability to protect your engine. Think of it like this: fresh oil is like giving your engine a refreshing drink, while old oil is like making it drink sludge. Not good, right?

Dirty oil can lead to a bunch of problems. It can cause your engine to overheat, reduce fuel efficiency, and even lead to serious damage. Regular oil changes ensure that your engine is always running with clean, fresh oil, which keeps everything working as it should. Most manufacturers recommend changing your oil every 3,000 to 7,500 miles, but it's always best to check your owner's manual for the specific recommendations for your 2018 Nissan Altima SR. Ignoring these recommendations can shorten the lifespan of your engine and lead to costly repairs down the road.

Moreover, regular oil changes contribute to better fuel economy. When your engine is properly lubricated with clean oil, it doesn't have to work as hard, which translates to better gas mileage. This can save you a significant amount of money on fuel over the long run. Additionally, clean oil helps to keep your engine clean by trapping contaminants and preventing them from building up inside the engine. This reduces the risk of sludge and deposits that can clog engine components and reduce performance. So, by keeping up with your oil changes, you're not just protecting your engine; you're also improving your car's overall efficiency and performance. It’s a win-win situation!

What You'll Need

Before we get started, let's gather all the stuff you'll need. Having everything on hand will make the process smooth and easy. Here’s a list:

New Oil: Check your owner's manual for the correct type and amount. For the 2018 Nissan Altima SR, you'll likely need about 4.8 quarts of 0W-20 synthetic oil.
New Oil Filter: Again, refer to your owner's manual or a parts store to find the right one for your car. A good quality oil filter ensures that your oil stays clean for longer.
Wrench: You'll need a wrench to remove the oil drain plug. Make sure you have the right size.
Oil Filter Wrench: This will help you remove the old oil filter.
Drain Pan: To catch the old oil. Trust me, you don't want to skip this step unless you want a big mess.
Funnel: To pour the new oil into the engine without spilling.
Gloves: To keep your hands clean. No one likes greasy hands.
Rags or Shop Towels: For wiping up any spills.
Jack and Jack Stands: To safely lift your car. Never work under a car supported only by a jack.

Having all these items ready will save you time and frustration. It’s also a good idea to have a flashlight handy in case you need extra light under the car. Safety is key, so make sure your jack and jack stands are in good condition and rated to support the weight of your vehicle. Taking a few extra minutes to prepare will make the oil change process much smoother and safer.

Step-by-Step Guide

Okay, let's get to the fun part! Follow these steps, and you'll have your oil changed in no time.

Warm Up the Engine: Run the engine for a few minutes to warm the oil. Warm oil flows more easily.
Secure the Car: Lift your car with a jack and secure it with jack stands. Safety first!
Locate the Oil Drain Plug: This is usually on the bottom of the oil pan. Consult your car's manual if you're not sure.
Position the Drain Pan: Place the drain pan under the drain plug.
Remove the Drain Plug: Use your wrench to carefully remove the drain plug. Let the oil drain completely.
Remove the Old Oil Filter: Use the oil filter wrench to loosen and remove the old filter. Be prepared for some oil to spill.
Install the New Oil Filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. Screw the new filter on by hand until it's snug. Then, tighten it another half to three-quarters of a turn.
Reinstall the Drain Plug: Clean the drain plug and install a new crush washer if needed. Tighten the drain plug to the manufacturer's specified torque. Overtightening can damage the oil pan.
Lower the Car: Carefully lower the car back to the ground.
Add New Oil: Open the oil fill cap on top of the engine and use a funnel to pour in the correct amount of new oil. Check your owner's manual for the exact quantity.
Check the Oil Level: Use the dipstick to check the oil level. Add more oil if needed.
Start the Engine: Run the engine for a few minutes and check for leaks around the drain plug and oil filter.
Final Check: Turn off the engine and check the oil level one last time. Top off if necessary.

Remember to dispose of the old oil and filter properly. Many auto parts stores will accept used oil for recycling. Following these steps carefully will ensure that your oil change is done correctly and safely.

Choosing the Right Oil and Filter

Selecting the right oil and filter is crucial for the longevity and performance of your 2018 Nissan Altima SR. Using the recommended oil type ensures that your engine receives the proper lubrication and protection it needs. The 2018 Nissan Altima SR typically requires 0W-20 synthetic oil. This type of oil is designed to provide excellent performance in a variety of temperatures and driving conditions. Always refer to your owner's manual to confirm the specific oil requirements for your vehicle. Using the wrong type of oil can lead to reduced fuel efficiency, increased engine wear, and potentially even engine damage.

When it comes to oil filters, quality matters. A good oil filter effectively removes contaminants from the oil, preventing them from circulating through the engine and causing wear. Look for oil filters from reputable brands that are known for their quality and performance. Some oil filters are designed to last longer, providing extended protection between oil changes. Consider the driving conditions you typically encounter. If you frequently drive in dusty or dirty environments, a higher-quality oil filter can provide extra protection. Investing in a good oil filter is a small price to pay for the peace of mind knowing that your engine is well-protected.

Additionally, consider synthetic oil blends or full synthetic oil for enhanced engine protection. Synthetic oils are engineered to provide superior lubrication, better resistance to breakdown, and improved performance in extreme temperatures compared to conventional oils. While synthetic oils may be more expensive, their benefits can outweigh the cost, especially for vehicles like the 2018 Nissan Altima SR that are designed to perform optimally with synthetic oil. Ultimately, choosing the right oil and filter is a critical part of maintaining your vehicle and ensuring its long-term reliability.

Tips and Tricks

Here are a few extra tips to make your oil change even easier:

Warm Oil, Not Hot: Warm oil flows better, but be careful not to burn yourself.
Don't Overtighten: Overtightening the drain plug or oil filter can cause damage.
Use a Funnel: A funnel will prevent spills and make pouring the new oil much easier.
Double-Check Everything: Before starting the engine, double-check that the drain plug and oil filter are securely tightened.
Keep Records: Keep a record of your oil changes to stay on schedule.

By following these tips, you can ensure that your oil changes are quick, easy, and effective. Keeping your car properly maintained will help you save money on costly repairs in the long run. Plus, you'll have the satisfaction of knowing that you're taking good care of your vehicle. So, grab your tools, gather your supplies, and get ready to give your 2018 Nissan Altima SR the oil change it deserves!

What to Do After the Oil Change

Once you've completed the oil change, there are a few important steps to take to ensure everything is running smoothly. First, double-check the oil level using the dipstick. Make sure the oil is at the correct level, adding more if necessary. It's always better to add a little at a time to avoid overfilling. Next, start the engine and let it run for a few minutes. Listen for any unusual noises or leaks. If you notice anything out of the ordinary, shut off the engine and investigate.

After running the engine, check the area around the drain plug and oil filter for any signs of leaks. If you spot a leak, tighten the drain plug or oil filter as needed. However, be careful not to overtighten, as this can cause damage. It's also a good idea to reset the oil life monitoring system in your car's computer. Refer to your owner's manual for instructions on how to do this. Resetting the system ensures that you receive accurate reminders for your next scheduled oil change.

Finally, properly dispose of the used oil and oil filter. Many auto parts stores and recycling centers accept used oil for recycling. This helps to protect the environment and ensures that the oil is disposed of safely. By taking these post-oil change steps, you can ensure that your 2018 Nissan Altima SR continues to run smoothly and efficiently. Regular maintenance, including oil changes, is essential for prolonging the life of your vehicle and preventing costly repairs.

Conclusion

So, there you have it! Changing the oil in your 2018 Nissan Altima SR isn't as scary as it might seem. With the right tools and a little bit of patience, you can easily do it yourself.
