Today, we're diving into how to perform an oil change on your 2018 Subaru Forester. Doing it yourself saves money and gives you a great sense of accomplishment. Let's get started!

    Why Change Your Own Oil?

    Changing your own oil isn't just about saving a few bucks, although that's a definite perk! It's about understanding your car better and ensuring it gets the best possible care. When you take your car to a shop, you're trusting someone else to do the job right. But when you do it yourself, you have complete control over the process. You get to choose the quality of oil and filter, ensuring they meet or exceed Subaru's specifications. Plus, it gives you a chance to inspect other components under the car, like the brakes, tires, and suspension, catching potential issues early on before they turn into costly repairs. Regular oil changes are the lifeblood of your engine, keeping it running smoothly and efficiently for years to come.

    DIY oil changes also provide a deeper connection with your vehicle. You learn about its inner workings and develop a better understanding of its needs. This knowledge empowers you to make informed decisions about its maintenance and care, leading to a longer lifespan and improved performance. Plus, there's a certain satisfaction that comes from knowing you're taking proactive steps to protect your investment and keep your Subaru Forester in top condition. So, while it might seem like a small task, changing your own oil is a significant way to show your car some love and keep it running like a champ. By understanding the importance and benefits of DIY oil changes, you're not just saving money; you're investing in the long-term health and performance of your 2018 Subaru Forester.

    Step-by-Step Guide

    Okay, with our tools and supplies ready, let’s dive into the step-by-step process of changing the oil on your 2018 Subaru Forester. Safety is paramount, so make sure you're working in a well-ventilated area and take your time.

    1. Prepare the Car:

      • Warm up the engine slightly by letting it run for a few minutes. This helps the oil flow more easily.
      • Park your Forester on a level surface. Engage the parking brake.
      • Use a jack and jack stands (or ramps) to safely lift the front of the car. Never work under a car supported only by a jack. Place the jack stands securely under the vehicle's frame.

    2. Locate and Remove the Drain Plug:

      • Position the drain pan under the oil drain plug. It's usually located on the bottom of the oil pan.
      • Use the correct size wrench to loosen and remove the drain plug. Be careful, as the oil may be hot. Let the oil drain completely into the pan.
      • Once the oil has finished draining, inspect the drain plug and replace the crush washer if necessary. This helps ensure a tight seal.
      • Reinstall the drain plug and tighten it to the manufacturer's specified torque (usually around 30 ft-lbs). Don't overtighten!

    3. Remove the Old Oil Filter:

      • Locate the oil filter. On the 2018 Forester, it's typically on the top of the engine.
      • Use the oil filter wrench to loosen and remove the old oil filter. Have a rag ready to catch any spills.
      • Before installing the new filter, lightly lubricate the rubber gasket with fresh oil. This helps create a good seal.

    4. Install the New Oil Filter:

      • Screw the new oil filter into place by hand until the gasket makes contact with the engine. Then, tighten it another ¾ of a turn. Don't overtighten!

    5. Add New Oil:

      • Locate the oil fill cap on the engine. Remove the cap.
      • Place the funnel into the oil fill opening.
      • Pour in the correct amount of new oil, as specified in your owner's manual (usually around 5.1 quarts).
      • Replace the oil fill cap.

    6. Check the Oil Level:

      • Remove the dipstick, wipe it clean, and reinsert it fully.
      • Pull the dipstick out again and check the oil level. It should be between the minimum and maximum marks. Add more oil if needed.

    7. Start the Engine and Check for Leaks:

      • Start the engine and let it run for a few minutes.
      • Check around the drain plug and oil filter for any leaks. If you see any leaks, tighten the connections as needed.
      • Turn off the engine.

    8. Lower the Car:

      • Carefully lower the car using the jack. Remove the jack stands or ramps.

    9. Dispose of the Old Oil Properly:

      • Take the used oil to a local recycling center or auto parts store for proper disposal. Never pour used oil down the drain or onto the ground.

    Tips and Tricks for a Smooth Oil Change

    Changing your oil can be straightforward, but a few tips and tricks can make the process even smoother. First off, always double-check that you have the right type of oil and filter for your specific 2018 Subaru Forester. Using the wrong oil can negatively impact your engine's performance and longevity. Refer to your owner's manual for the manufacturer's recommendations. Another helpful tip is to warm up your engine slightly before draining the old oil. This allows the oil to flow more freely, ensuring that you remove as much of the old, dirty oil as possible. However, be cautious, as the oil can be hot, so wear gloves and take necessary precautions.

    Also, when removing the old oil filter, be prepared for some spillage. Placing a rag or shop towel underneath the filter can help catch any drips and prevent a mess. Lightly lubricating the rubber gasket on the new oil filter with fresh oil before installation ensures a proper seal and prevents leaks. Tighten the filter by hand until the gasket makes contact with the engine, then tighten it another ¾ of a turn. Avoid overtightening, as this can damage the filter or the engine. Remember to replace the crush washer on the drain plug each time you change your oil. This small, inexpensive part helps create a tight seal and prevents leaks. When reinstalling the drain plug, tighten it to the manufacturer's specified torque to avoid damaging the oil pan. Finally, after completing the oil change, double-check the oil level using the dipstick and add more oil if needed to reach the proper level. These tips will not only streamline the oil change process but also help ensure that you're doing it correctly, protecting your engine and saving you money in the long run.

    Choosing the Right Oil and Filter

    Choosing the right oil and filter for your 2018 Subaru Forester is crucial for maintaining its performance and longevity. Subaru typically recommends using a 0W-20 full synthetic oil for the 2018 Forester. Synthetic oils provide better protection against wear and tear, especially in extreme temperatures, compared to conventional oils. They also tend to last longer, which can extend the intervals between oil changes. However, always refer to your owner's manual for the specific oil type and viscosity recommended for your vehicle, as it may vary depending on your driving conditions and climate.

    As for the oil filter, it's generally a good idea to use a high-quality filter that meets or exceeds Subaru's specifications. A genuine Subaru oil filter is often a safe bet, as it's designed specifically for your engine and ensures optimal filtration. However, there are also many reputable aftermarket brands that offer excellent oil filters for the Forester. When choosing a filter, look for one with a good filtration efficiency rating and a durable construction. A well-designed filter will effectively remove contaminants from the oil, preventing them from circulating through the engine and causing damage. Regularly changing both the oil and filter at the recommended intervals is essential for keeping your engine clean and running smoothly. By investing in quality oil and filters, you're not just maintaining your vehicle; you're protecting your investment and ensuring that your 2018 Subaru Forester continues to perform at its best for years to come. Ultimately, the right combination of oil and filter will help to maximize your engine's lifespan and efficiency.

    Disposal of Used Oil

    Proper disposal of used oil is not only environmentally responsible, but it's also often required by law. Never pour used oil down the drain, onto the ground, or into a storm sewer, as it can contaminate soil and water sources. Instead, collect the used oil in a sealed container and take it to a designated collection center for recycling. Many auto parts stores, service stations, and local recycling centers accept used oil for free. These facilities have the equipment and processes in place to safely recycle the oil, preventing it from harming the environment.

    Recycling used oil not only conserves resources but also reduces the demand for new oil production. When oil is recycled, it can be re-refined and used again as a lubricant or fuel. This helps to reduce our dependence on fossil fuels and minimize the environmental impact of oil extraction and refining. In addition to recycling the oil itself, you should also properly dispose of the used oil filter. Some recycling centers will accept oil filters, while others may require you to drain the filter and dispose of it separately. Check with your local recycling center for specific instructions on how to dispose of used oil filters in your area. By taking the time to properly dispose of used oil and filters, you're doing your part to protect the environment and ensure a sustainable future. So, make sure to plan ahead and locate a nearby collection center before you begin your oil change, and always follow the local regulations for used oil disposal.

    Conclusion

    So, there you have it! You've successfully changed the oil in your 2018 Subaru Forester. Regular oil changes are crucial for keeping your engine running smoothly and efficiently. Doing it yourself not only saves you money but also gives you a better understanding of your car. Keep up with the maintenance, and your Forester will thank you with years of reliable service. Happy driving!
