Hey guys! Changing your oil is one of the most important things you can do to keep your 2021 Subaru Crosstrek running smoothly. It's like giving your car a regular health checkup! This guide will walk you through each step, making it super easy, even if you've never done it before. We'll cover everything from gathering your supplies to disposing of the old oil properly. So, grab your tools, and let's get started!

Why Change Your Own Oil?

Changing your own oil might seem intimidating, but it's actually pretty straightforward, and there are tons of benefits. First off, you'll save a bunch of money compared to taking it to a shop. Oil changes at dealerships or quick lube places can be surprisingly expensive, and those savings add up over time. Plus, doing it yourself means you know exactly what kind of oil and filter are going into your engine. You can choose high-quality products that will help your Crosstrek last longer. Also, there's a certain satisfaction in knowing you're taking good care of your car. It's a great way to get to know your vehicle better and feel more connected to it. Beyond the financial and personal perks, regular oil changes are crucial for your engine's health. Clean oil lubricates all the moving parts, reduces friction, and helps keep everything cool. Over time, oil breaks down and gets contaminated with dirt and debris, which can lead to increased wear and tear, reduced performance, and even engine damage. By changing your oil regularly, you're ensuring that your engine stays in top condition, which can prevent costly repairs down the road. So, whether you're a seasoned DIYer or a complete beginner, changing your own oil is a worthwhile skill to learn.

Gathering Your Supplies

Before you get started, it's crucial to gather all the necessary supplies. Trust me, you don't want to be halfway through the job and realize you're missing something! Here’s a comprehensive list to make sure you’re fully prepared. First, you’ll need the right type of oil. For the 2021 Subaru Crosstrek, check your owner's manual for the recommended oil type and viscosity. Typically, it’s a synthetic blend or full synthetic 0W-20 oil, but always double-check to be sure. You'll also need an oil filter specifically designed for your Crosstrek. Again, your owner's manual or a quick search online will help you find the correct part number. Next, grab an oil filter wrench to easily remove the old filter. These wrenches come in various sizes and styles, so make sure you get one that fits your filter properly. You'll also need a wrench to remove the oil drain plug. The size will vary, so consult your manual or use a socket set to find the right fit. An oil drain pan is essential to catch the old oil as it drains from the engine. Choose one that’s large enough to hold all the oil, usually around 5-6 quarts. A funnel will help you pour the new oil into the engine without making a mess. Get one with a long spout to easily reach the oil filler opening. You’ll also need some basic tools like a jack and jack stands to safely lift your Crosstrek. Never work under a car supported only by a jack! Safety is paramount. Don't forget gloves to keep your hands clean and protected from the oil. Also, have some rags or paper towels on hand to wipe up any spills. Lastly, you’ll need a torque wrench to tighten the drain plug and oil filter to the correct specifications. This prevents leaks and ensures everything is properly secured. Once you have all these supplies ready, you’re all set to begin the oil change process. Having everything within reach will make the job go smoothly and efficiently.

Step-by-Step Guide to Changing Your Oil

Alright, let's dive into the actual oil change process for your 2021 Subaru Crosstrek. Follow these steps carefully, and you'll be a pro in no time! First, you need to prepare your Crosstrek. Start by warming up the engine for a few minutes. This helps the oil flow more easily. Then, park your car on a level surface and engage the parking brake. Safety first! Next, use your jack and jack stands to safely lift the front of your Crosstrek. Make sure the jack stands are securely positioned under the vehicle's frame. Now, locate the oil drain plug underneath the engine. Place your oil drain pan directly beneath the plug to catch the old oil. Use your wrench to carefully loosen the drain plug. Once it's loose, unscrew it by hand, being careful as the oil will start flowing out. Let the oil drain completely, which usually takes about 15-20 minutes. While the oil is draining, you can remove the old oil filter. Use your oil filter wrench to loosen the filter. Once it's loose, unscrew it by hand, being careful as some oil will spill. Lightly lubricate the rubber gasket on the new oil filter with fresh oil. This helps create a good seal. Screw the new oil filter onto the engine by hand until the gasket makes contact, then tighten it an additional ¾ turn. Refer to the filter's instructions for specific tightening guidelines. Once the oil has completely drained, clean the drain plug and install a new crush washer if necessary. Then, screw the drain plug back into the oil pan by hand, and use your torque wrench to tighten it to the manufacturer's specifications. This prevents leaks and ensures it's properly secured. Now, lower your Crosstrek back to the ground by carefully removing the jack stands and lowering the vehicle with the jack. Open the hood and locate the oil filler cap. Remove the cap and insert your funnel. Pour in the correct amount of new oil as specified in your owner's manual. For the 2021 Crosstrek, it's usually around 5 quarts, but always double-check. Replace the oil filler cap and start the engine. Let it run for a few minutes, then check the oil level using the dipstick. Add more oil if needed to reach the proper level. Finally, check for any leaks around the drain plug and oil filter. If you see any leaks, tighten them slightly. And that’s it! You’ve successfully changed the oil in your 2021 Subaru Crosstrek.

Choosing the Right Oil and Filter

Choosing the right oil and filter is super important for keeping your 2021 Subaru Crosstrek running its best. Not all oils are created equal, and using the wrong type can actually harm your engine. So, let's break down what you need to know to make the best choices. First, let's talk about oil types. For the 2021 Crosstrek, Subaru typically recommends a synthetic blend or full synthetic 0W-20 oil. Synthetic oils are designed to provide better protection and performance than conventional oils, especially in extreme temperatures. They also tend to last longer, which means you can go longer between oil changes. Always check your owner's manual to confirm the exact recommendation for your vehicle. Using the correct viscosity, in this case 0W-20, is also crucial. Viscosity refers to the oil's thickness, and using the wrong viscosity can affect how well the oil lubricates your engine. Now, let's move on to oil filters. A good oil filter is essential for removing contaminants from the oil and keeping your engine clean. There are many different brands and types of oil filters available, so how do you choose the right one? Look for a filter that's specifically designed for your Subaru Crosstrek. You can find this information in your owner's manual or by searching online. Consider using a high-quality filter from a reputable brand. These filters often have better construction and filtration capabilities. Some popular brands include Subaru, Mobil 1, and K&N. When in doubt, it's always a good idea to consult with a mechanic or auto parts store employee. They can help you choose the right oil and filter for your specific vehicle and driving conditions. Remember, investing in high-quality oil and filters is an investment in the long-term health and performance of your Crosstrek. It can help prevent costly repairs down the road and keep your engine running smoothly for years to come.

Proper Disposal of Used Oil

Okay, so you've successfully changed your oil – awesome! But proper disposal of used oil is just as important as the oil change itself. You can't just dump it down the drain or toss it in the trash! Used oil is a hazardous waste and can contaminate the environment if not handled correctly. So, let's go over the right way to dispose of it. The first step is to find a designated collection center. Many auto parts stores, like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, will accept used oil for free. You can also check with your local recycling center or waste management facility to see if they have a collection program. Before you head to the collection center, make sure your used oil is properly contained. Pour the oil into a leak-proof container with a secure lid. The original oil bottles are often a good option, or you can purchase a专门designed oil collection container. Be careful not to spill any oil during the transfer. Once your oil is safely contained, transport it to the collection center. When you arrive, they'll usually have a designated area for you to drop off the oil. Follow their instructions and make sure to dispose of the container properly as well. In addition to used oil, you should also properly dispose of your used oil filter. Many collection centers will also accept used oil filters. To prepare the filter for disposal, drain as much of the remaining oil as possible. You can do this by puncturing the filter and letting it drain into your oil drain pan. Then, place the filter in a sealed plastic bag before taking it to the collection center. Recycling used oil is a great way to protect the environment. Used oil can be re-refined and used again, reducing the need for new oil production. By properly disposing of your used oil, you're doing your part to keep our planet clean and healthy. So, don't skip this important step! It's a small effort that makes a big difference.
