Hey guys! Are you a proud owner of a 2018 Nissan Altima SR and thinking about tackling that oil change yourself? Awesome! Changing your own oil is not only a great way to save some cash, but it also gives you a chance to bond with your car. This guide is specifically tailored for your Altima SR, ensuring you get the job done right. Let's dive in!

Why Change Your Oil?

Before we get our hands dirty, let's quickly chat about why regular oil changes are so important. Your engine oil is the lifeblood of your car's engine. Engine oil lubricates all those moving parts, reducing friction and wear. Over time, the oil breaks down, gets contaminated with dirt and debris, and loses its ability to do its job effectively. This can lead to some serious problems down the road, like decreased engine performance, poor fuel economy, and even catastrophic engine failure. Nobody wants that, right? Regular oil changes keep your engine running smoothly, efficiently, and extend its lifespan. Think of it as giving your car a regular dose of vitamins to keep it healthy and strong. So, how often should you be changing your oil? For the 2018 Nissan Altima SR, most manufacturers recommend an oil change every 5,000 to 7,500 miles under normal driving conditions. If you do a lot of stop-and-go driving, towing, or live in a dusty environment, you might want to shorten that interval. Check your owner's manual for the specific recommendation for your vehicle. Ignoring these guidelines can lead to long-term engine damage, which is way more expensive than a simple oil change. Plus, keeping up with regular maintenance like oil changes can also help maintain your car's resale value. A well-maintained car is always more attractive to potential buyers. So, changing your oil isn't just about saving money; it's about protecting your investment and ensuring your Altima SR stays reliable for years to come. Now that we've covered the why, let's get to the how!

What You'll Need

Alright, let's gather our supplies. To successfully complete an oil change on your 2018 Nissan Altima SR, you'll need a few essential items. First, and most importantly, you'll need the correct type and amount of engine oil. Check your owner's manual to confirm the recommended oil viscosity and capacity for your specific engine. Typically, the 2018 Altima SR uses a synthetic blend or full synthetic 0W-20 oil, but always double-check to be sure. Next up is an oil filter. Again, make sure you get the correct one for your Altima SR. You can usually find this information at your local auto parts store or online. A new drain plug washer is also a good idea. These are inexpensive and help ensure a tight seal, preventing leaks. You'll also need a wrench to remove the drain plug and the oil filter. The size of the drain plug wrench can vary, so consult your owner's manual or a reliable online resource. An oil filter wrench is specifically designed to grip and remove the oil filter. A drain pan is crucial for catching the old oil. Make sure it's large enough to hold the entire capacity of your engine. You'll also want a funnel to help pour the new oil into the engine without making a mess. A pair of gloves will keep your hands clean and protected. Rags or shop towels are essential for wiping up spills and cleaning surfaces. Safety glasses are a must to protect your eyes from splashes. And finally, wheel ramps or a jack and jack stands will safely elevate your car, giving you enough room to work underneath. Remember, safety first! Having all these tools and supplies on hand before you start will make the oil change process much smoother and more efficient. No one wants to be halfway through the job and realize they're missing something. Preparation is key to a successful DIY oil change.

Step-by-Step Guide

Okay, let's get down to business! Here's a step-by-step guide to changing the oil in your 2018 Nissan Altima SR:

1. Prepare Your Car: Start by warming up your engine for a few minutes. This helps the oil flow more easily. Then, safely lift your Altima SR using either wheel ramps or a jack and jack stands. Always use jack stands for safety! Never work under a car supported only by a jack.
2. Locate the Drain Plug: Once your car is safely elevated, locate the oil drain plug on the bottom of the oil pan. Place your drain pan directly underneath the drain plug.
3. Remove the Drain Plug: Using the correct size wrench, carefully loosen and remove the drain plug. Be prepared for the oil to start flowing out. Let the oil drain completely. This may take 15-20 minutes.
4. Replace the Drain Plug Washer: While the oil is draining, take this opportunity to replace the drain plug washer with a new one. This ensures a tight seal and prevents leaks.
5. Reinstall the Drain Plug: Once the oil has completely drained, reinstall the drain plug and tighten it to the manufacturer's specified torque. Overtightening can damage the oil pan.
6. Remove the Old Oil Filter: Locate the oil filter. Place the drain pan underneath the filter to catch any spills. Use an oil filter wrench to loosen and remove the old oil filter. Be careful, as the filter will contain some oil.
7. Prepare the New Oil Filter: Before installing the new oil filter, lightly lubricate the rubber gasket with fresh oil. This helps create a good seal.
8. Install the New Oil Filter: Screw the new oil filter into place by hand until the gasket makes contact with the engine. Then, tighten it an additional ¾ turn, according to the filter manufacturer's instructions. Do not overtighten.
9. Lower Your Car: Carefully lower your Altima SR back to the ground.
10. Add New Oil: Open the hood and locate the oil fill cap. Remove the cap and insert a funnel. Pour in the correct amount of new oil, as specified in your owner's manual.
11. Check the Oil Level: After adding the oil, replace the oil fill cap and start the engine. Let it run for a few minutes, then turn it off. Wait a few minutes for the oil to settle, then check the oil level using the dipstick. Add more oil if needed to reach the correct level.
12. Check for Leaks: Inspect the drain plug and oil filter for any leaks. If you see any leaks, tighten the connections as needed.
13. Reset the Oil Life Indicator: Reset the oil life indicator in your car's system, following the instructions in your owner's manual.
14. Dispose of Used Oil Properly: Properly dispose of the used oil and filter at a designated recycling center. Do not pour it down the drain or into the ground.

Choosing the Right Oil and Filter

Selecting the right oil and filter for your 2018 Nissan Altima SR is super important for maintaining its performance and longevity. Let's break down what you need to consider. First, your owner's manual is your best friend here. It will specify the exact oil type and viscosity recommended for your engine. For most 2018 Altima SR models, you're likely looking at a 0W-20 synthetic blend or full synthetic oil. Synthetic oils generally offer better protection against wear and tear, especially in extreme temperatures, compared to conventional oils. While they might be a bit more expensive, the added benefits for your engine are often worth the investment. Now, let's talk brands. There are tons of oil brands out there, and it can be overwhelming to choose. Reputable brands like Mobil 1, Castrol, Pennzoil, and Valvoline are generally safe bets. Look for oils that meet or exceed the standards set by the American Petroleum Institute (API). As for the oil filter, again, your owner's manual or a quick search at your local auto parts store will help you identify the correct filter for your Altima SR. Brands like Bosch, Fram, K&N, and Mobil 1 all offer quality oil filters. Consider using a synthetic oil filter for extended performance, especially if you plan on extending your oil change intervals (though always stick to the manufacturer's recommendations). The key is to choose a filter that effectively removes contaminants and maintains good oil flow. Don't skimp on the filter; a high-quality filter can make a big difference in protecting your engine. Ultimately, the best oil and filter for your Altima SR are the ones that meet the manufacturer's specifications and provide the level of protection you're comfortable with. Reading reviews and doing a little research can help you make an informed decision. And remember, regular oil changes with the right oil and filter are crucial for keeping your engine running smoothly for years to come.

Safety First!

Before you even think about reaching for a wrench, let's talk safety. Changing your oil might seem like a simple task, but it's important to take precautions to protect yourself. First and foremost, always work in a well-ventilated area. Exhaust fumes can be harmful, so make sure you have plenty of fresh air circulating. Eye protection is non-negotiable. Safety glasses will shield your eyes from any splashes or debris. Trust me, you don't want to get used oil in your eyes! Gloves are also a must. They'll keep your hands clean and protect them from the chemicals in the oil. When lifting your car, always use jack stands. Never, ever work under a car supported only by a jack. Jacks can fail, and the consequences can be catastrophic. Make sure the jack stands are properly positioned and securely supporting the vehicle before you get underneath. Be careful when working with hot oil. It can cause serious burns. Let the engine cool down for a bit before you start draining the oil. And when you're handling the drain plug and oil filter, be mindful of the hot surfaces. When you're finished, dispose of the used oil and filter properly. Most auto parts stores will accept used oil for recycling. Never pour it down the drain or into the ground. It's harmful to the environment. And finally, take your time. Rushing through the job can lead to mistakes and injuries. Focus on what you're doing and be careful. A little patience and attention to detail will go a long way in ensuring a safe and successful oil change. Remember, your safety is the top priority. So, take the necessary precautions and you'll be able to change your oil with confidence.

Disposal of Used Oil

Okay, you've successfully changed your oil – awesome! But the job's not quite done yet. Properly disposing of your used oil is just as important as the oil change itself. Why? Because used oil is a hazardous waste that can contaminate the environment if not handled correctly. So, what's the right way to get rid of it? The easiest and most environmentally friendly option is to take it to a recycling center. Many auto parts stores, like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, will accept used oil for free. They have collection tanks specifically designed for this purpose. Just make sure to transport the oil in a sealed container to prevent any spills. Some local government agencies and waste management companies also offer oil recycling programs. Check with your city or county to see if there are any drop-off locations near you. When you take your used oil to a recycling center, they'll typically filter it, remove contaminants, and re-refine it into new oil. This process helps conserve resources and reduces pollution. Never, ever pour used oil down the drain, into the sewer, or onto the ground. This can contaminate waterways, harm wildlife, and pollute the soil. It's also illegal in many areas. Similarly, don't throw used oil in the trash. It can leach into landfills and cause environmental problems. The used oil filter also needs to be disposed of properly. Some recycling centers will accept used oil filters, while others may require you to drain the oil from the filter and dispose of it separately. Check with your local recycling center for their specific requirements. By taking the time to properly dispose of your used oil, you're doing your part to protect the environment and keep our planet healthy. It's a small effort that makes a big difference.

Conclusion

So there you have it! Changing the oil in your 2018 Nissan Altima SR is totally doable with a little preparation and the right guidance. Not only will you save some money, but you'll also gain a better understanding of your car's mechanics. Remember to always prioritize safety, use the correct oil and filter, and dispose of the used oil responsibly. Happy wrenching, and keep your Altima SR running smoothly for years to come!
