Hey guys! Let's dive into the crucial topic of selecting the right oil type for your 2017 Subaru Legacy. Getting this right is super important for keeping your engine running smoothly and extending its life. We'll cover everything you need to know, from understanding the manufacturer's recommendations to exploring different oil types and brands. So, buckle up and let's get started!

Understanding the Manufacturer's Recommendations

When it comes to your 2017 Subaru Legacy, the manufacturer's recommendations are your holy grail. These guidelines, typically found in your owner's manual, are based on extensive testing and engineering to ensure optimal engine performance and longevity. Ignoring these recommendations can lead to serious engine problems down the road, and nobody wants that, right?

First off, let's talk about viscosity. The owner's manual will specify the recommended oil viscosity grade, such as 0W-20 or 5W-30. This number indicates the oil's thickness and how it flows at different temperatures. Using the wrong viscosity can affect how well the oil lubricates the engine's components, potentially causing increased wear and tear. For example, if the manual recommends 0W-20, using a thicker oil like 10W-40 might not properly lubricate the engine during cold starts, especially in colder climates. This can lead to increased friction and premature engine wear.

Beyond viscosity, the manufacturer also specifies the oil quality standards. Look for designations like API (American Petroleum Institute) and ILSAC (International Lubricant Standardization and Approval Committee). These certifications ensure that the oil meets certain performance standards and provides adequate protection for your engine. Using oils that meet these standards guarantees that the oil contains the necessary additives to prevent corrosion, reduce sludge buildup, and protect against wear. Always check the oil bottle for the API starburst symbol and the ILSAC GF-5 or GF-6 designation to confirm that it meets the required quality standards.

Subaru might also recommend synthetic oil or a synthetic blend for your 2017 Legacy. Synthetic oils generally offer better protection against extreme temperatures, resist breakdown better than conventional oils, and can improve fuel economy. While synthetic oils tend to be more expensive, the added benefits can outweigh the cost in the long run, especially if you plan to keep your car for many years. Moreover, synthetic oils often allow for longer oil change intervals, potentially saving you time and money on maintenance.

Finally, always consult your owner's manual for any specific Subaru requirements. Some manufacturers have unique specifications for their engines, and using an oil that meets these requirements is crucial. Ignoring these specific recommendations could void your warranty or lead to engine damage. For instance, some Subaru engines are particularly sensitive to certain additives, and using a specifically formulated oil can help prevent issues like oil consumption or engine knocking.

Exploring Different Oil Types

Now that we know the importance of following the manufacturer's recommendations, let's explore the different types of oil available for your 2017 Subaru Legacy. Understanding the characteristics of each type will help you make an informed decision based on your driving habits and budget.

Conventional Oil

Conventional oil, also known as mineral oil, is the most basic type of engine oil. It is refined directly from crude oil and offers adequate lubrication for most engines. However, it doesn't perform as well as synthetic oils in extreme temperatures and tends to break down more quickly. This means you'll need to change it more frequently, typically every 3,000 to 5,000 miles. Conventional oil is the most affordable option, making it a popular choice for older vehicles or those with less demanding driving conditions. If you primarily drive short distances in moderate temperatures, conventional oil might be sufficient for your needs. However, keep in mind that it might not provide the best protection for your engine in the long run, especially if you frequently engage in stop-and-go driving or tow heavy loads.

Synthetic Blend Oil

Synthetic blend oil is a mixture of conventional and synthetic oils, offering a compromise between cost and performance. It provides better protection than conventional oil, especially in colder temperatures, and lasts longer between oil changes, typically every 5,000 to 7,000 miles. Synthetic blend oils are a good option for drivers who want improved protection without the higher cost of full synthetic oil. They are particularly well-suited for vehicles that experience moderate temperature variations and occasional heavy-duty use. For example, if you live in an area with mild winters and occasionally tow a small trailer, a synthetic blend oil could be a cost-effective choice.

Full Synthetic Oil

Full synthetic oil is the highest quality engine oil available. It is chemically engineered to provide superior lubrication, better protection against extreme temperatures, and longer oil change intervals, often up to 7,500 to 10,000 miles or more. Full synthetic oils also resist breakdown better than conventional and synthetic blend oils, maintaining their viscosity and protective properties for a longer period. While it's the most expensive option, full synthetic oil can extend the life of your engine and improve fuel economy. It's highly recommended for vehicles that experience harsh driving conditions, such as frequent stop-and-go traffic, towing, or extreme temperatures. If you want the best possible protection for your 2017 Subaru Legacy, especially if you plan to keep it for many years, full synthetic oil is the way to go.

High-Mileage Oil

High-mileage oil is specifically formulated for vehicles with over 75,000 miles. It contains additives that help to condition seals, reduce leaks, and clean sludge buildup. High-mileage oils can also improve oil pressure and reduce oil consumption in older engines. If your 2017 Subaru Legacy has accumulated a significant number of miles, switching to high-mileage oil can help to maintain its performance and extend its life. These oils often contain seal conditioners that help to rejuvenate worn seals and prevent leaks, as well as detergents that help to remove deposits and keep the engine clean. While high-mileage oil is not a substitute for mechanical repairs, it can help to address some of the common issues associated with older engines.
