Choosing the right oil for your 2017 Subaru Legacy is super important. Using the correct oil ensures your engine runs smoothly and lasts longer. So, let's dive into everything you need to know about the best oil for your ride!

Understanding the Basics of Engine Oil

Okay, guys, let's start with the basics. Engine oil is like the lifeblood of your car. It lubricates all the moving parts in your engine, reducing friction and wear. Without it, your engine would overheat and eventually seize up – not a fun situation! Oil also helps to clean your engine by carrying away dirt, debris, and combustion byproducts. Over time, oil breaks down and becomes less effective, which is why regular oil changes are crucial.

There are a few main types of engine oil: conventional, synthetic blend, and full synthetic. Conventional oil is the most basic and generally the least expensive. Synthetic blend oil is a mix of conventional and synthetic oils, offering better performance than conventional alone. Full synthetic oil is the highest quality, providing superior lubrication, better high-temperature performance, and improved engine protection. For a sophisticated engine like the one in your 2017 Subaru Legacy, using the right type of oil can make a big difference.

Viscosity is another critical factor. It refers to the oil's thickness and how it flows at different temperatures. You'll often see oil viscosity ratings like 5W-30 or 0W-20. The first number (with the "W" for winter) indicates how the oil flows in cold temperatures, while the second number indicates how it flows at operating temperatures. Using the correct viscosity ensures that the oil can properly lubricate your engine in all conditions. Always refer to your car's manual to find the manufacturer's recommended oil type and viscosity.

Additives are also a key component of engine oil. These additives enhance the oil's performance by providing benefits such as detergents to clean the engine, corrosion inhibitors to prevent rust, and friction modifiers to reduce wear. High-quality oils often contain a better blend of additives, which can further improve your engine's performance and longevity. When choosing an oil, consider those that advertise specific additives designed to protect your engine.

Finally, remember that oil change intervals are important. Most manufacturers recommend changing your oil every 3,000 to 5,000 miles for conventional oil, and every 7,500 to 10,000 miles for synthetic oil. However, it's always best to check your car's manual for the specific recommendations. Regular oil changes keep your engine clean and well-lubricated, preventing costly repairs down the road.

Recommended Oil Type for the 2017 Subaru Legacy

For the 2017 Subaru Legacy, the manufacturer typically recommends using 0W-20 full synthetic oil. This type of oil is designed to provide excellent protection and performance for your engine. Full synthetic oil offers superior lubrication, better resistance to high temperatures, and enhanced engine cleaning capabilities compared to conventional or synthetic blend oils. Using the recommended oil ensures that your Subaru Legacy's engine operates efficiently and reliably.

The 0W-20 viscosity rating indicates that the oil flows well in both cold and hot temperatures. The "0W" part means it has excellent cold-weather flow, which is crucial for starting your engine in cold conditions. The "20" part means it maintains adequate thickness at high operating temperatures, ensuring proper lubrication and protection when the engine is hot. This viscosity is specifically chosen to meet the demands of the Subaru Legacy's engine, providing optimal performance and fuel efficiency.

Subaru engines, including the one in the 2017 Legacy, are known for their boxer design, which places unique demands on the engine oil. The horizontally opposed cylinders require oil that can handle specific lubrication needs and temperature variations. Full synthetic 0W-20 oil is formulated to meet these demands, ensuring that all engine components receive adequate lubrication and protection. Using the recommended oil helps prevent premature wear and tear, extending the life of your engine.

It's also important to consider the driving conditions when choosing an oil. If you frequently drive in extreme conditions, such as very hot or cold weather, or if you often tow heavy loads, you may want to consider more frequent oil changes or even a higher-performance synthetic oil. Consult with a trusted mechanic or refer to your car's manual for specific recommendations based on your driving habits.

When selecting a brand of oil, look for reputable brands that meet or exceed the industry standards set by organizations like the American Petroleum Institute (API). These standards ensure that the oil has been tested and certified to meet certain performance requirements. Choosing a certified oil gives you confidence that you are using a high-quality product that will protect your engine.

Lastly, remember that using the correct oil type and viscosity is not just about performance; it also affects your car's warranty. Using an oil that does not meet the manufacturer's specifications can potentially void your warranty in case of engine damage. Always follow the recommendations in your car's manual to ensure that you are using the correct oil and maintaining your warranty coverage.

Why Full Synthetic Oil is Best for Your Subaru Legacy

So, why is full synthetic oil the best choice for your 2017 Subaru Legacy? Let's break it down, guys.
