This guide will walk you through everything you need to know to get the job done right. We'll cover the tools you'll need, the steps involved, and even some helpful tips to make the process smooth and easy. Let's dive in!

What You'll Need

Before we get started, let's make sure you have all the necessary supplies. Nothing's worse than getting halfway through and realizing you're missing something! Here’s your checklist:

• New Oil: The 2018 Nissan Altima SR typically takes around 4.8 quarts of 0W-20 synthetic oil. Always double-check your owner's manual to confirm the exact amount and type recommended for your specific engine. Using the correct oil is crucial for engine performance and longevity.
• New Oil Filter: A new oil filter is a must every time you change your oil. Again, refer to your owner's manual or a parts store to find the correct filter for your 2018 Altima SR. Brands like Bosch, Mobil 1, and K&N are popular choices, but any filter that meets the manufacturer's specifications will work.
• Wrench for the Oil Filter: You'll need a special wrench to remove the old oil filter. These come in various styles, such as cap-type or strap-type. Make sure you get one that fits your specific oil filter size. Trust me, trying to remove an oil filter without the right tool is a recipe for frustration.
• Wrench for the Drain Plug: The oil drain plug on your Altima SR will require a specific size wrench, usually a 14mm or 17mm socket. Have both sizes on hand just in case.
• Oil Drain Pan: This is essential for catching the old oil as it drains. Choose a pan with a decent capacity to avoid any spills.
• Funnel: A funnel will help you pour the new oil into the engine without making a mess. A clean funnel is a happy funnel!
• Gloves: Protect your hands from getting dirty with a pair of disposable gloves. Nitrile gloves are a good option.
• Rags or Shop Towels: You'll need these to wipe up any spills or drips.
• Jack and Jack Stands (or Ramps): You'll need to safely lift your car to access the oil drain plug and oil filter. Jack stands are essential for safety. Never work under a car supported only by a jack. Ramps are a convenient alternative if you have them.
• Wheel chocks: For safety, you need to secure the wheels that will remain on the ground.

Having all these items ready before you start will make the oil change process much smoother and more efficient. Preparation is key!

Step-by-Step Oil Change Guide

Alright, with all your tools and supplies gathered, let's get down to business. Here's a detailed step-by-step guide to changing the oil in your 2018 Nissan Altima SR:

1. Prepare Your Car:
   • Warm-Up the Engine: Start your car and let it run for a few minutes. This will warm the oil, making it flow more easily. However, don't let it get too hot, or you risk burning yourself.
   • Secure the Vehicle: Park your car on a level surface. Engage the parking brake and place wheel chocks behind the rear wheels. This prevents the car from accidentally rolling.
   • Lift the Car: Using a jack, lift the front of your car and securely place jack stands under the frame rails. Never work under a car supported only by a jack! If you're using ramps, drive the car onto the ramps carefully.
2. Locate the Oil Drain Plug:
   • Crawl under the car and locate the oil pan. It's usually a large metal pan at the bottom of the engine. The oil drain plug is a bolt located on the bottom or side of the oil pan.
3. Drain the Old Oil:
   • Position the oil drain pan under the drain plug.
   • Using the correct size wrench, carefully loosen the drain plug. Be prepared for the oil to start flowing as soon as you break the seal.
   • Completely remove the drain plug, allowing the old oil to drain fully into the pan. This may take 10-15 minutes.
   • Inspect the drain plug and replace the crush washer if it looks worn or damaged. A new crush washer ensures a tight seal and prevents leaks.
4. Remove the Old Oil Filter:
   • Locate the oil filter. It's usually near the engine block and may be accessible from under the car or from the engine compartment.
   • Position the oil drain pan under the oil filter to catch any spills.
   • Use your oil filter wrench to loosen the old oil filter. Once it's loose, you should be able to unscrew it by hand.
   • Before installing the new oil filter, lightly lubricate the rubber gasket with fresh oil. This helps create a good seal.
5. Install the New Oil Filter:
   • Screw the new oil filter onto the engine by hand until the gasket makes contact with the engine block. Then, tighten it another ¾ to 1 full turn, as specified on the filter. Avoid overtightening, as this can damage the filter or the engine.
6. Reinstall the Drain Plug:
   • Once the oil has completely drained, clean the drain plug and install a new crush washer if necessary.
   • Tighten the drain plug to the manufacturer's specified torque. If you don't have a torque wrench, tighten it snugly but don't overtighten it. Overtightening can damage the oil pan.
7. Add New Oil:
   • Locate the oil fill cap on top of the engine. Remove the cap.
   • Insert a funnel into the oil fill opening.
   • Pour in the correct amount of new oil, as specified in your owner's manual (usually around 4.8 quarts for the 2018 Altima SR).
8. Check the Oil Level:
   • Remove the dipstick, wipe it clean, and reinsert it fully.
   • Remove the dipstick again and check the oil level. It should be between the minimum and maximum marks on the dipstick. Add more oil if necessary.
9. Start the Engine:
   • Start the engine and let it run for a few minutes. Check for any leaks around the oil drain plug and oil filter.
   • Turn off the engine and recheck the oil level. Add more oil if needed.
10. Reset the Oil Life Monitor:
    • Follow the instructions in your owner's manual to reset the oil life monitor. This will remind you when it's time for your next oil change.
11. Dispose of the Old Oil Properly:
    • Take the used oil and oil filter to a local recycling center or auto parts store for proper disposal. Do not pour used oil down the drain or into the environment.

Congratulations! You've successfully changed the oil in your 2018 Nissan Altima SR. Give yourself a pat on the back!

Pro Tips for a Smooth Oil Change

• Read the Owner's Manual: Always refer to your owner's manual for specific instructions and recommendations for your vehicle.
• Use the Right Oil: Using the correct type and weight of oil is crucial for engine performance and longevity. Don't skimp on quality here.
• Don't Overtighten: Overtightening the drain plug or oil filter can damage the components. Use a torque wrench if possible, and always err on the side of caution.
• Be Patient: Allow the old oil to drain completely before reinstalling the drain plug. This will help remove more contaminants from the engine.
• Clean Up Any Spills: Clean up any spills immediately to prevent them from staining your driveway or garage floor.
• Keep Records: Keep a record of your oil changes, including the date, mileage, and type of oil used. This will help you track your maintenance schedule.

Troubleshooting Common Issues

Even with careful planning, you might encounter a few snags. Here's how to handle some common problems:

• Drain Plug Stripped: If the drain plug is stripped, you may need to use a larger size drain plug or have the oil pan repaired.
• Oil Filter Stuck: If the oil filter is stuck, try using a different type of oil filter wrench or tapping it gently with a hammer to loosen it.
• Oil Leak: If you notice an oil leak after the oil change, check the drain plug and oil filter to make sure they are properly tightened. Also, inspect the crush washer on the drain plug.
• Difficulty Removing the Old Filter: Make sure you have the correct oil filter wrench. Sometimes, gently tapping the filter with a screwdriver (carefully!) can help break it loose. As a last resort, you can puncture the filter and use a screwdriver for leverage, but be extremely careful not to damage the engine.

Why Change Your Own Oil?

Changing your own oil might seem intimidating at first, but it offers several benefits:

• Cost Savings: You'll save money on labor costs compared to taking your car to a mechanic.
• Quality Control: You can ensure that the job is done correctly and that high-quality oil and filters are used.
• Vehicle Knowledge: You'll gain a better understanding of your car's mechanics and maintenance needs.
• Sense of Accomplishment: There's a certain satisfaction that comes from performing your own car maintenance.

So, there you have it! Changing the oil in your 2018 Nissan Altima SR is a straightforward process that anyone can do with the right tools and a little bit of know-how. Just remember to take your time, follow the steps carefully, and always prioritize safety. Happy wrenching!
