Hey guys! Changing the oil in your 2021 Subaru Crosstrek might seem daunting, but trust me, it's totally something you can handle yourself. Not only will you save some cash, but you'll also get to know your car a little better. This guide breaks down the process into easy-to-follow steps, so even if you're not a seasoned mechanic, you'll be able to get the job done right. Let's dive in!

Why Change Your Oil?

Before we jump into the how-to, let's quickly cover the why. Engine oil is the lifeblood of your Crosstrek's engine. Its primary job is to lubricate all those moving parts, preventing them from grinding against each other and causing serious damage. Think of it like this: without oil, your engine would be like a rusty, squeaky swing set – not good! Over time, oil breaks down, gets contaminated with dirt and debris, and loses its ability to protect your engine effectively. That's why regular oil changes are crucial for keeping your Crosstrek running smoothly for years to come.

Clean oil ensures optimal engine performance, improves fuel efficiency, and extends the life of your engine. Neglecting oil changes can lead to a buildup of sludge, which restricts oil flow and causes overheating. In severe cases, this can result in engine failure – a repair that will cost you way more than a few oil changes! So, taking the time to change your oil is an investment in the long-term health of your vehicle.

Regular oil changes also give you a chance to inspect other components of your car, such as the air filter, belts, and hoses. Catching potential problems early can prevent them from turning into major headaches down the road. Plus, it's just a good habit to get into as a responsible car owner. So, grab your tools, and let's get started!

What You'll Need

Alright, before you start wrenching, you'll need to gather a few essential supplies. Having everything on hand will make the process smoother and less stressful. Here's a list of what you'll need:

• New Oil: Check your owner's manual for the correct type and amount of oil for your 2021 Subaru Crosstrek. Typically, it's a synthetic 0W-20 oil, but always double-check! Knowing the capacity is important to avoid overfilling or underfilling. Your owner's manual is your friend here – don't skip this step!
• New Oil Filter: Again, refer to your owner's manual or a reliable auto parts store to find the correct oil filter for your vehicle. Using the wrong filter can cause problems, so make sure you get the right one. A quality filter will help keep your oil clean and your engine protected.
• Wrench: You'll need a wrench to remove the oil drain plug. Make sure you have the correct size for your Crosstrek. Using the wrong size can strip the plug, which is a major pain to fix. A good set of wrenches is a valuable addition to any DIYer's toolbox.
• Oil Filter Wrench: This tool will help you remove the old oil filter. There are different types of oil filter wrenches available, so choose one that fits your filter and is easy to use. Some people can remove the filter by hand, but an oil filter wrench makes the job much easier and prevents you from getting frustrated.
• Drain Pan: You'll need a pan to catch the old oil as it drains from the engine. Make sure it's large enough to hold all the oil (usually around 5 quarts) and that it's in good condition. A leaky drain pan will make a mess, so choose wisely.
• Funnel: A funnel will help you pour the new oil into the engine without spilling it. This is especially helpful if you're working in a tight space. A clean funnel will prevent contamination of the new oil.
• Gloves: Protect your hands from getting dirty and greasy by wearing gloves. Disposable gloves are a good option, or you can use reusable work gloves.
• Rags or Shop Towels: You'll need these to wipe up any spills or drips. Keep a stack of them handy.
• Jack and Jack Stands (Optional): If you need more clearance to reach the oil drain plug, you can use a jack and jack stands to lift the vehicle. Always use jack stands for safety – never work under a vehicle supported only by a jack!

Having all these supplies ready will make the oil change process much smoother and more efficient. Trust me, you don't want to be running to the store in the middle of the job!

Step-by-Step Guide

Okay, now for the main event! Follow these steps carefully, and you'll have your 2021 Subaru Crosstrek purring like a kitten in no time.

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. However, don't let it get too hot – you don't want to burn yourself.
2. Prepare the Vehicle: Park your Crosstrek on a level surface and engage the parking brake. If you need more clearance, use a jack and jack stands to lift the vehicle. Remember, safety first!
3. Locate the Oil Drain Plug: The oil drain plug is located on the bottom of the engine oil pan. Consult your owner's manual if you're not sure where it is. It's usually a large bolt.
4. Position the Drain Pan: Place the drain pan under the oil drain plug to catch the old oil. Make sure the pan is properly positioned to avoid any spills.
5. Remove the Oil Drain Plug: Using the correct size wrench, carefully loosen and remove the oil drain plug. Be prepared for the oil to start flowing out quickly. Let it drain completely.
6. Remove the Old Oil Filter: Locate the oil filter. It's usually near the engine block. Use the oil filter wrench to loosen and remove the old oil filter. Be careful, as there will be some oil inside the filter. Dispose of the old filter properly.
7. Prepare the New Oil Filter: Lightly lubricate the rubber gasket on the new oil filter with fresh oil. This will help create a good seal. Screw the new oil filter onto the engine by hand until it's snug. Do not overtighten it.
8. Reinstall the Oil Drain Plug: Once the oil has completely drained, clean the oil drain plug and install a new crush washer (if applicable). Tighten the drain plug to the manufacturer's specified torque. Overtightening can damage the oil pan.
9. Add New Oil: Remove the oil filler cap on top of the engine. Using a funnel, pour in the correct amount of new oil as specified in your owner's manual. Be careful not to overfill.
10. Check the Oil Level: After adding the oil, replace the oil filler cap and start the engine. Let it run for a few minutes, then turn it off and check the oil level using the dipstick. Add more oil if needed to reach the proper level.
11. Inspect for Leaks: Check around the oil drain plug and oil filter for any leaks. If you see any leaks, tighten the connections as needed.
12. Reset the Oil Life Monitor: Consult your owner's manual for instructions on how to reset the oil life monitor. This will remind you when it's time for your next oil change.

Pro Tips and Tricks

• Warm Oil is Your Friend: As mentioned earlier, warming up the engine slightly before draining the oil helps it flow more easily. Just be careful not to burn yourself on hot engine parts.
• Don't Overtighten: Overtightening the oil drain plug or oil filter can damage the threads or crush the filter. Use the correct torque specifications and avoid using excessive force.
• Use a New Crush Washer: If your oil drain plug uses a crush washer, always replace it with a new one. This will help ensure a good seal and prevent leaks.
• Proper Disposal: Dispose of the old oil and filter properly. Many auto parts stores will accept used oil for recycling. Do not pour it down the drain or into the environment.
• Keep a Record: Keep a record of your oil changes, including the date, mileage, and type of oil used. This will help you stay on top of your maintenance schedule.

When to Consult a Professional

While changing your own oil can save you money and give you a sense of accomplishment, there are times when it's best to consult a professional mechanic. If you're not comfortable working on your car, or if you encounter any problems during the oil change process, don't hesitate to seek professional help. It's better to be safe than sorry when it comes to your vehicle's engine.

Also, if you notice any unusual noises or warning lights after changing your oil, take your car to a mechanic right away. This could indicate a serious problem that needs to be addressed immediately.
