So, you're looking to change the oil in your 2018 Nissan Altima SR, huh? Awesome! Doing your own oil changes is a great way to save some cash and get to know your car a little better. Don't worry, it's not as intimidating as it might seem. This guide will walk you through each step, making the process smooth and straightforward. We'll cover everything from gathering your supplies to properly disposing of the old oil. So, let's dive in and get your Altima running smoothly!

What You'll Need

Before you get started, gather all the necessary tools and supplies. This will make the entire process much smoother and prevent you from having to run to the store mid-oil change. Here's a comprehensive list to ensure you're well-prepared:

  • New Oil: The most crucial supply! For a 2018 Nissan Altima SR, you'll typically need about 4.8 quarts of 0W-20 synthetic oil. However, always double-check your owner's manual to confirm the exact specification and quantity. Using the correct type of oil is vital for your engine's performance and longevity. Using the wrong type or amount of oil can seriously damage your engine, leading to costly repairs down the line. Always consult your owner's manual or a trusted mechanic if you're unsure about the correct oil type.
  • New Oil Filter: An oil change isn't complete without replacing the oil filter. A dirty oil filter can restrict oil flow and reduce its effectiveness. Make sure you get the correct oil filter for your 2018 Altima SR. You can usually find this information in your owner's manual or at your local auto parts store. They'll likely ask for your car's year, make, and model to ensure you get the right one. The oil filter is responsible for trapping contaminants and debris, preventing them from circulating through your engine. Over time, the filter becomes clogged, reducing its ability to do its job effectively. Replacing it ensures that your engine is receiving clean, filtered oil, which is essential for optimal performance and preventing wear and tear.
  • Wrench: You'll need a wrench to remove the oil drain plug. The size will vary, so check your owner's manual or use a socket set to find the right fit. Make sure the wrench fits snugly to avoid stripping the drain plug. Stripping the drain plug can create a huge headache and potentially require professional repair. A good quality wrench will provide the necessary leverage and grip to loosen the plug without damaging it.
  • Oil Filter Wrench: This specialized wrench is designed to grip and remove the oil filter. There are different types available, so choose one that fits your oil filter size. Some common types include cap-type wrenches and band-type wrenches. The oil filter wrench provides the necessary grip to loosen the filter, which can often be on very tight. Trying to remove it by hand can be difficult, if not impossible. Using the correct wrench will save you time and frustration.
  • Drain Pan: A container to catch the old oil. Make sure it's large enough to hold all the oil from your engine (around 5 quarts). An adequately sized drain pan prevents spills and makes the disposal process much cleaner and easier. Choose a drain pan with a wide opening to minimize the risk of splashing. Some drain pans also come with convenient pouring spouts to facilitate the transfer of the used oil into a container for recycling.
  • Funnel: To pour the new oil into the engine without spilling. A funnel is a simple but essential tool that prevents messy spills and ensures that all the oil goes where it's supposed to go. Using a funnel will save you time and cleanup. Look for a funnel with a flexible spout for easier access to the oil fill port.
  • Gloves: To keep your hands clean. Nitrile gloves are a good option as they are resistant to oil and chemicals. Wearing gloves protects your skin from irritation and exposure to potentially harmful substances. Choose gloves that fit well and provide a good grip. Disposable gloves are convenient for easy cleanup.
  • Rags or Shop Towels: For cleaning up any spills. Having plenty of rags or shop towels on hand is essential for wiping up drips, spills, and messes. They'll keep your workspace clean and prevent oil from spreading. Shop towels are more durable and absorbent than regular paper towels.
  • Jack and Jack Stands: To safely lift the car and provide access to the oil drain plug and filter. Never work under a car supported only by a jack. Jack stands are crucial for safety. Place them securely under the vehicle's frame before proceeding. Ensure the jack stands are rated to support the weight of your vehicle. Using jack stands is non-negotiable when working under a car. Your safety is paramount.
  • Wheel Chocks: To prevent the car from rolling. Place them behind the rear wheels for added safety. Wheel chocks provide an extra layer of security and prevent the car from accidentally rolling while you're working on it. They're especially important if you're working on a sloped surface.

Step-by-Step Guide

Okay, now that you've got everything you need, let's get down to business! Follow these steps carefully to ensure a successful oil change:

  1. Prepare the Car: Start by warming up the engine. Let it run for a few minutes. Warm oil flows more easily, making the draining process more efficient. However, be careful not to let the engine get too hot, as you could burn yourself. After warming it up, turn off the engine and engage the parking brake. This is a crucial safety step.
  2. Secure the Vehicle: Place wheel chocks behind the rear wheels. Then, use the jack to lift the front of the car. Consult your owner's manual for the correct jacking points. Once the car is lifted, place jack stands securely under the frame. Never work under a car supported only by a jack! This is extremely dangerous and could result in serious injury or death. Double-check that the jack stands are properly positioned and supporting the vehicle's weight before proceeding.
  3. Locate the Oil Drain Plug: Crawl under the car and locate the oil drain plug. It's usually on the bottom of the oil pan. Place the drain pan directly underneath the plug. Ensure that the drain pan is positioned correctly to catch all the oil. You don't want to make a mess!
  4. Remove the Drain Plug: Using the correct wrench, carefully loosen the drain plug. Once it's loose, unscrew it by hand, being careful as the oil will be hot. Let the old oil drain completely into the pan. This may take several minutes. Be patient and allow all the oil to drain out for a more thorough oil change. While the oil is draining, you can move on to the next step.
  5. Remove the Old Oil Filter: Locate the oil filter. It's usually near the engine block. Use the oil filter wrench to loosen and remove the old oil filter. Be prepared for some oil to spill when you remove the filter, so keep a rag handy. Dispose of the old filter properly. Some auto parts stores will recycle them for you.
  6. Install the New Oil Filter: Before installing the new oil filter, lightly lubricate the rubber gasket with fresh oil. This will help create a good seal. Screw the new filter on by hand until it's snug. Then, use the oil filter wrench to tighten it about another half to three-quarters of a turn. Don't overtighten it, as this could damage the filter or the engine block.
  7. Reinstall the Drain Plug: Once all the old oil has drained, clean the drain plug and install a new crush washer (if applicable). This will ensure a tight seal and prevent leaks. Screw the drain plug back in by hand until it's snug. Then, use the wrench to tighten it to the manufacturer's specified torque. Consult your owner's manual or a repair manual for the correct torque specification. Overtightening the drain plug can damage the oil pan. Not tightening it enough can cause leaks. Getting it just right is important.
  8. Lower the Car: Carefully remove the jack stands and lower the car back to the ground. Make sure the area is clear before lowering the car. Lowering the car slowly and smoothly will prevent any damage.
  9. Add New Oil: Open the hood and locate the oil fill cap. Remove the cap and insert the funnel. Pour in the correct amount of new oil, as specified in your owner's manual. Remember, for a 2018 Nissan Altima SR, it's usually around 4.8 quarts of 0W-20 synthetic oil. Be careful not to overfill. It's always better to add a little less and then check the level.
  10. 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, and then check the oil level using the dipstick. Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the level. The oil level should be between the minimum and maximum marks on the dipstick. Add more oil if needed to reach the correct level.
  11. Check for Leaks: After starting the engine, check for any leaks around the oil drain plug and the oil filter. If you see any leaks, tighten the connections slightly. If the leaks persist, consult a mechanic.
  12. Reset the Maintenance Light: Refer to your owner's manual for instructions on how to reset the oil maintenance light. This will vary depending on the model.

Proper Disposal of Used Oil

Okay, you've successfully changed your oil! But we're not quite done yet. It's super important to dispose of the used oil and filter properly. Here's how:

  • Do NOT pour it down the drain or into the ground. This is incredibly harmful to the environment and illegal in most places.
  • Take the used oil to a local auto parts store or recycling center. Most auto parts stores will accept used oil for free. They have the proper equipment to recycle it safely.
  • Place the used oil filter in a sealed plastic bag to prevent any leaks and take it to the same place where you're disposing of the oil.
