Hey there, Subaru enthusiasts! Changing your oil is one of the most important things you can do to keep your 2018 Subaru Impreza running smoothly for years to come. It might seem intimidating at first, but trust me, it's totally doable with the right guidance. In this article, we'll walk you through each step, providing you with all the tips and tricks you need to confidently perform an oil change on your Impreza. Let's get started and keep that engine purring like a kitten!

Why is Oil Change Important for Your 2018 Subaru Impreza?

Oil changes are the lifeblood of your engine, guys! Without regular oil changes, your engine is basically running a marathon without water. The engine oil’s main job is to lubricate all the moving parts within your engine. Over time, this oil breaks down, gets contaminated with dirt and debris, and loses its ability to protect your engine effectively. Dirty oil can lead to increased friction, overheating, and ultimately, engine damage. Think of it like this: fresh, clean oil keeps everything gliding smoothly, while old, sludgy oil is like trying to run through mud. Not fun, right? Regularly changing your oil ensures that your engine stays properly lubricated, cool, and clean, preventing premature wear and tear. This simple maintenance task can save you from costly repairs down the road and keep your Impreza running like a champ. Moreover, adhering to the recommended oil change intervals can also improve your car's fuel efficiency. A well-lubricated engine doesn't have to work as hard, which translates to better gas mileage. So, by keeping up with your oil changes, you're not just protecting your engine; you're also saving money at the pump. It’s a win-win situation, really! Ignoring oil changes can lead to a buildup of sludge and deposits in your engine. This buildup restricts oil flow, causing critical engine components to starve for lubrication. The result? Increased wear on bearings, pistons, and other vital parts, potentially leading to catastrophic engine failure. Trust me, replacing an engine is a far more expensive endeavor than a simple oil change. So, take the time to change your oil regularly, and your Impreza will thank you for it with years of reliable performance. It's a small investment that pays off big time in the long run.

Gathering Your Supplies

Alright, before we dive into the nitty-gritty, let's make sure you have everything you need. Here’s a checklist of essential supplies for your 2018 Subaru Impreza oil change:

• New Oil Filter: Make sure you get the correct one for your 2018 Impreza. Using the wrong filter can cause problems, so double-check the part number.
• The Right Type and Amount of Oil: Check your owner's manual for the recommended oil type and quantity. Typically, the 2018 Impreza uses synthetic oil, and you'll likely need around 5 quarts.
• Wrench: You'll need this to remove the oil filter and the drain plug. Make sure it fits properly to avoid stripping the bolts.
• Oil Filter Wrench: This special wrench helps you grip and remove the old oil filter.
• Drain Pan: To catch the old oil. Don't pour it down the drain, guys! We'll talk about proper disposal later.
• 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 and keeping things tidy.
• Jack and Jack Stands (Optional): If you need more clearance to reach the drain plug, use a jack and jack stands to safely lift the car.
• Wheel Chocks (Optional): For added safety, place wheel chocks behind the rear wheels.

Having all these supplies on hand before you start will make the process much smoother and less stressful. There's nothing worse than getting halfway through an oil change and realizing you're missing a crucial tool or supply. So, take a few minutes to gather everything together, and you'll be well-prepared to tackle the job. Remember, safety first! If you're using a jack and jack stands, make sure the car is securely supported before you start working underneath it. And always wear gloves to protect your hands from the oil and grime. With a little preparation, you can make your oil change experience a breeze. Don't be afraid to ask for help at your local auto parts store if you're unsure about which oil filter or oil type to use. They can help you find the correct parts for your 2018 Subaru Impreza, ensuring that you're using the right products for your vehicle. Also, consider investing in a good quality oil filter wrench. A cheap, flimsy wrench can slip and make it difficult to remove the old oil filter. A sturdy, well-designed wrench will make the job much easier and prevent any unnecessary frustration.

Okay, with all your supplies gathered, let’s get down to business! Follow these steps carefully to change the oil in your 2018 Subaru Impreza:

1. Warm Up the Engine: Run the engine for a few minutes to warm up the oil. This helps it flow more easily.
2. Secure the Vehicle: If you need more room, use a jack and jack stands to lift the front of the car. Make sure it's stable and secure before you start working underneath. Use wheel chocks for extra safety.

8. Install the New Oil Filter: Screw the new oil filter into place by hand until it's snug. Then, tighten it another ¾ turn with the oil filter wrench.
9. Reinstall the Drain Plug: Once the oil has completely drained, clean the drain plug and reinstall it. Tighten it securely with the wrench, but don't overtighten.
10. Lower the Vehicle: If you used a jack and jack stands, carefully lower the car back to the ground.
11. Add New Oil: Open the oil fill cap on top of the engine and use the funnel to pour in the correct amount of new oil. Check your owner's manual for the exact quantity.
