Hey guys! Changing your own oil can save you some serious cash and give you a great sense of accomplishment. If you're the proud owner of a 2017 Subaru Legacy 2.5i, you're in the right place! This guide will walk you through the entire oil change process, step-by-step, making it easy even if you've never done it before. We'll cover everything from gathering the right materials to properly disposing of the old oil. So, grab your tools, and let's get started!

Why Change Your Own Oil?

Before we dive in, let's talk about why you might want to tackle this yourself. First off, money savings! Dealerships and quick-lube places charge a premium for oil changes. Doing it yourself can cut those costs significantly. Second, you get to know your car better. Popping the hood and getting your hands dirty helps you understand how things work under there. Third, you have control over the quality of products used. You can choose the specific oil and filter that you trust and that are best suited for your Subaru. Finally, there's the satisfaction factor. It feels good to maintain your own vehicle and know you're keeping it running smoothly.

Changing your car's oil is crucial for its longevity and performance. Oil lubricates the engine's 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 effectively, leading to increased engine wear, reduced fuel efficiency, and potential engine damage. Regular oil changes ensure that your engine is always running with clean, fresh oil, keeping it in top condition.

Subaru recommends specific oil change intervals for the 2017 Legacy 2.5i. Typically, it's around 6,000 miles or 6 months, but always refer to your owner's manual for the exact recommendation. Following these intervals helps maintain your warranty and ensures optimal engine performance. Ignoring oil change intervals can lead to serious engine problems down the road, which can be far more expensive than regular maintenance. So, staying on top of your oil changes is a smart investment in the long-term health of your vehicle.

What You'll Need

Alright, let's gather the gear you'll need for this oil change adventure. Here's a handy checklist:

• New Oil: Check your owner's manual, but the 2017 Subaru Legacy 2.5i typically requires 0W-20 synthetic oil. The quantity is usually around 5.1 quarts (4.8 liters), but double-check to be sure.
• New Oil Filter: A Subaru OEM oil filter is always a good choice, or a reputable aftermarket brand like Purolator, Mobil 1, or K&N.
• Wrench for the Oil Filter: An oil filter wrench that fits your specific filter size. There are several types, including cap-type, strap-type, and claw-type.
• Socket Wrench and Socket for the Drain Plug: The size of the drain plug socket is typically 17mm or 14mm, but check your specific vehicle.
• Drain Pan: To catch the old oil. Make sure it's large enough to hold all the oil from your engine.
• Funnel: To pour the new oil into the engine without making a mess.
• Gloves: To keep your hands clean.
• Rags or Shop Towels: For wiping up spills.
• Jack and Jack Stands (or Ramps): To safely lift your car.
• Wheel Chocks: For added safety.

Make sure you have all of these items before you start. There's nothing worse than getting halfway through the job and realizing you're missing something!

When selecting your oil, it's crucial to choose the right type and viscosity. The 2017 Subaru Legacy 2.5i is designed to use 0W-20 synthetic oil. Using the correct oil ensures proper lubrication and optimal engine performance. Synthetic oil provides better protection against wear and tear, especially in extreme temperatures. It also lasts longer than conventional oil, which means you can extend your oil change intervals slightly. However, always follow the manufacturer's recommendations for oil change intervals.

Choosing the right oil filter is just as important as choosing the right oil. A high-quality oil filter will effectively remove contaminants from the oil, preventing them from circulating through the engine and causing damage. Subaru OEM oil filters are a reliable choice, as they are specifically designed for Subaru engines. Reputable aftermarket brands like Purolator, Mobil 1, and K&N also offer high-quality oil filters that provide excellent filtration and durability. Avoid using cheap, no-name oil filters, as they may not provide adequate filtration and could potentially damage your engine.

Step-by-Step Oil Change Guide

Okay, with all your supplies in hand, let's get down to business. Follow these steps carefully, and you'll have that oil changed in no time!

Step 1: Prepare Your Vehicle

1. Warm up the engine: Run the engine for a few minutes to warm the oil. This helps it flow more easily.
2. Park on a level surface: Make sure your car is parked on a flat, even surface.
3. Engage the parking brake: Set the parking brake firmly.
4. Chock the rear wheels: Place wheel chocks behind the rear wheels for added safety.
5. Lift the vehicle: Use a jack to lift the front of the car. Place jack stands securely under the frame rails. Never work under a car supported only by a jack! Alternatively, you can use ramps to drive the front of the car up.

Step 2: Drain the Old Oil

1. Locate the oil drain plug: It's usually on the bottom of the oil pan. Consult your owner's manual if you're not sure.
2. Position the drain pan: Place the drain pan under the drain plug.
3. Remove the drain plug: Use the correct size socket wrench to loosen and remove the drain plug. Be careful, as the oil may be hot. Let the oil drain completely.
4. Inspect the drain plug: Check the drain plug for any damage. Replace the crush washer if necessary. A new crush washer 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. Don't overtighten it, as this can damage the oil pan.

Step 3: Replace the Oil Filter

1. Locate the oil filter: It's usually near the front of the engine. Again, consult your owner's manual if needed.
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 old 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 prepared for some oil to spill out.
5. Lubricate the new oil filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. This helps create a good seal.
6. Install the new oil filter: Screw the new oil filter on by hand until the gasket makes contact with the engine. Then, tighten it another 3/4 to 1 full turn. Don't overtighten it.

Step 4: Add New Oil

1. Locate the oil fill cap: It's usually on the top of the engine and marked with an oil can symbol.
2. Remove the oil fill cap: Unscrew the oil fill cap.
3. Insert the funnel: Place the funnel into the oil fill opening.
4. Add the new oil: Pour in the specified amount of new oil. For the 2017 Subaru Legacy 2.5i, it's usually around 5.1 quarts (4.8 liters). Check your owner's manual for the exact amount.
5. Check the oil level: Use the dipstick to check the oil level. Add more oil if needed to reach the
