Hey guys! Changing your own oil can save you some serious cash and keep your 2018 Nissan Altima SR running smoothly. This guide will walk you through each step, making it a breeze even if you're not a seasoned mechanic. Let's get started!

Why Change Your Oil?

Before we dive in, let's talk about why regular oil changes are so important. Your engine oil is the lifeblood of your car. It lubricates all the moving parts, reducing friction and preventing wear and tear. Over time, oil breaks down and becomes contaminated with dirt, debris, and combustion byproducts. This dirty oil can't do its job properly, leading to:

• Increased engine wear: Dirty oil can't protect your engine parts as well, leading to premature wear and tear.
• Reduced fuel efficiency: Sludgy oil makes your engine work harder, reducing your gas mileage.
• Overheating: Oil helps to dissipate heat. Old, dirty oil can't cool your engine effectively, potentially leading to overheating.
• Engine damage: In severe cases, neglecting oil changes can lead to serious engine damage and costly repairs.

So, changing your oil regularly is an investment in the long-term health and performance of your 2018 Nissan Altima SR. Think of it as a simple way to keep your ride happy and healthy!

What You'll Need

Alright, let's gather our supplies. You'll need:

• New Oil: Check your owner's manual for the correct type and amount of oil for your 2018 Nissan Altima SR. Generally, the 2.5L engine uses 5 quarts of 0W-20 synthetic oil. Using the correct type of oil is crucial for optimal engine performance and longevity.
• New Oil Filter: Again, consult your owner's manual or a parts store to find the correct oil filter for your car. A high-quality oil filter will help to remove contaminants from your oil, keeping your engine clean.
• Wrench: You'll need a wrench to remove the oil drain plug and the oil filter. Make sure you have the correct size for both.
• Oil Filter Wrench: An oil filter wrench makes removing the old filter much easier, especially if it's on tight.
• Drain Pan: A drain pan to catch the old oil. Make sure it's large enough to hold all the oil from your engine.
• Funnel: A funnel to pour the new oil into the engine without spilling.
• Rags or Shop Towels: For cleaning up any spills.
• Gloves: To protect your hands from the dirty oil.
• Jack and Jack Stands (Optional): If you need more clearance to access the drain plug and oil filter, you can use a jack and jack stands to lift the car. Safety first! Always use jack stands when working under a vehicle.
• Wheel chocks (Optional): For increased safety.

Step-by-Step Guide

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

Step 1: Prepare the Car

1. Warm up the engine: Run the engine for a few minutes to warm up the oil. Warm oil flows more easily, making it easier to drain. Don't let it get too hot, though, or you could burn yourself.
2. Park on a level surface: Park your car on a level surface and engage the parking brake.
3. Secure the wheels: Use wheel chocks behind the rear wheels for added safety.
4. Lift the car (Optional): If needed, use a jack to lift the front of the car and secure it with jack stands. Never work under a car supported only by a jack.

Step 2: Drain the Old Oil

1. Locate the oil drain plug: The oil drain plug is located on the bottom of the oil pan. Consult your owner's manual if you're not sure where it is.
2. Position the drain pan: Place the drain pan under the oil drain plug.
3. Remove the drain plug: Use the wrench to loosen and remove the drain plug. Be careful, as the oil may be hot. Let the oil drain completely. This may take 15-20 minutes.
4. Inspect the drain plug: Check the drain plug and its washer for any damage. Replace the washer if necessary.
5. Reinstall the drain plug: Once the oil has drained completely, reinstall the drain plug and tighten it to the manufacturer's specified torque. Don't overtighten it, or you could damage the oil pan.

Step 3: Replace the Oil Filter

1. Locate the oil filter: The oil filter is usually located near the engine block. Consult your owner's manual if you're not sure where it is.
2. Position the drain pan: Place the drain pan under the oil filter to catch any spills.
3. Loosen the oil filter: Use the oil filter wrench to loosen the oil filter. You may need to use some force to break it free.
4. Remove the oil filter: Unscrew the oil filter by hand. Be careful, as it will be full of oil.
5. Lubricate the new oil filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. This will help to create a good seal.
6. 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 of a turn. Don't overtighten it.

Step 4: Add New Oil

1. Locate the oil filler cap: The oil filler cap is usually located on the top of the engine. Consult your owner's manual if you're not sure where it is.
2. Remove the oil filler cap: Unscrew and remove the oil filler cap.
3. Insert the funnel: Insert the funnel into the oil filler neck.
4. Add the new oil: Pour the correct amount of new oil into the engine using the funnel. Check your owner's manual for the correct amount. For the 2018 Nissan Altima SR with the 2.5L engine, it's usually around 5 quarts.
5. Check the oil level: Use the dipstick to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick.
6. Replace the oil filler cap: Screw the oil filler cap back on.

Step 5: Final Steps

1. Start the engine: Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
2. Check the oil level again: After running the engine, check the oil level again and add more oil if necessary.
3. Reset the oil life monitoring system: Reset the oil life monitoring system according to the instructions in your owner's manual. This will remind you when it's time for your next oil change.
4. Dispose of the old oil properly: Take the old oil and oil filter to a recycling center or auto parts store for proper disposal. Don't pour it down the drain or into the ground.

Tips and Tricks

• Use the right tools: Using the correct tools will make the job easier and prevent damage to your car.
• Don't overtighten: Overtightening the drain plug or oil filter can damage the oil pan or engine block.
• Be patient: Take your time and don't rush. Changing your oil is a simple task, but it's important to do it right.
• Keep a record: Keep a record of your oil changes, including the date, mileage, and type of oil used. This will help you to keep track of your car's maintenance schedule.
• Double-check everything: Before you drive your car, double-check that the drain plug and oil filter are tight, the oil level is correct, and the oil filler cap is securely in place.
