Hey guys! Changing your own oil might seem intimidating, but trust me, it's totally doable, even on your 2018 Subaru Impreza. Not only will you save some cash, but you'll also get to know your car a little better. This guide will walk you through each step, making the process smooth and straightforward. Let's dive in!

Why Change Your Oil?

Before we get our hands dirty, let's talk about why regular oil changes are so crucial. Your engine oil is like the lifeblood of your car's engine. Its main job is to lubricate all those moving parts, preventing them from grinding against each other and causing serious wear and tear. Think of it as the ultimate friction fighter! Over time, however, the oil breaks down, gets contaminated with dirt and debris, and loses its ability to do its job effectively. This is where regular oil changes come in. Fresh, clean oil ensures your engine stays properly lubricated, runs smoothly, and lasts longer. Skipping oil changes can lead to some pretty nasty consequences, including decreased fuel efficiency, engine overheating, and even catastrophic engine failure. Trust me, you don't want that! So, making oil changes a regular part of your maintenance routine is one of the best things you can do to keep your 2018 Subaru Impreza running like a champ. It's a small investment that pays off big time in the long run by preventing costly repairs and extending the life of your engine. Plus, knowing you're taking good care of your car gives you peace of mind every time you hit the road. So, let's get to it and keep that Impreza purring!

What You'll Need

Okay, so you're ready to tackle that oil change? Awesome! First, let's gather all the necessary tools and supplies. Having everything on hand before you start will make the whole process much smoother and less frustrating. Here's a list of what you'll need:

• New Oil: Check your 2018 Subaru Impreza's owner's manual to find out the correct type and amount of oil you need. Typically, you'll need synthetic oil, likely 0W-20, but double-check to be sure. The quantity is usually around 5 quarts, but again, refer to your manual.
• New Oil Filter: Don't skimp on this! A new oil filter is essential for keeping your oil clean and your engine happy. Make sure you get the right filter for your specific model year Impreza. A reliable brand is always a good bet.
• Wrench: You'll need a wrench to remove the oil drain plug. The size can vary, so check your manual or use an adjustable wrench. Make sure it fits snugly to avoid stripping the plug.
• Oil Filter Wrench: This specialized wrench will help you remove the old oil filter. There are different types available, so choose one that works best for you.
• Drain Pan: You'll need a pan to catch the old oil as it drains. Make sure it's large enough to hold all the oil, and that it's easy to pour from when you're ready to dispose of the old oil.
• Funnel: A funnel will help you pour the new oil into the engine without making a mess. Trust me, you'll want this!
• Gloves: Protect your hands from getting covered in oil. Disposable gloves are a good option.
• Rags or Shop Towels: You'll need these to wipe up any spills or drips. Plenty of rags are always a good idea.
• Jack and Jack Stands (Optional): If you need more clearance to reach the drain plug and oil filter, you'll need a jack and jack stands to safely lift your car. Never work under a car supported only by a jack! Jack stands are crucial for safety.
• Wheel chocks (Optional): Use these if using a jack for added safety.

Having all these items ready will make your oil change a breeze. Now that you're all set, let's move on to the next step!

Step-by-Step Guide

Alright, let's get down to business! Follow these steps carefully, and you'll have that oil changed in no time. Safety first, though! Make sure your car is parked on a level surface and the parking brake is engaged.

1. Warm Up the Engine: Start your engine and let it run for a few minutes. This will warm up the oil, making it flow more easily. Don't let it run too long, though – you don't want the oil to be too hot.
2. Prepare the Car: If you need more clearance, use the jack to lift the front of your car. Place jack stands securely under the frame rails. Again, never work under a car supported only by a jack. Use wheel chocks behind the rear wheels.
3. Locate the Oil Drain Plug: Crawl under your car and find the oil drain plug on the bottom of the oil pan. It's usually a large bolt.
4. Position the Drain Pan: Place the drain pan directly under the oil drain plug.
5. Remove the Drain Plug: Using the correct wrench, carefully loosen the drain plug. Once it's loose, finish removing it by hand, being careful as the oil will start flowing out. Let the oil drain completely. This may take 10-15 minutes.
6. Remove the Old Oil Filter: While the oil is draining, locate the oil filter. It's usually near the front of the engine. Use the oil filter wrench to loosen the old filter. Once it's loose, unscrew it by hand. Be prepared for some oil to spill, so have a rag handy. Pro-tip: Put a plastic bag around the oil filter when removing to avoid spills.
7. Prepare 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, tighten it another half to three-quarters of a turn, according to the filter's instructions. Do not overtighten!
8. Reinstall the Drain Plug: Once the oil has completely drained, clean the drain plug and install a new crush washer (if applicable). 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.
9. Lower the Car: If you lifted your car, carefully lower it back down.
10. 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. It's usually around 5 quarts, but double-check.
11. Check the Oil Level: Replace the oil fill cap. Start the engine and let it run for a minute or two. Then, turn off the engine and wait a few minutes for the oil to settle. Check the oil level using the dipstick. Add more oil if needed to reach the
