Understanding the Recommended Oil Type

Okay, so you want to know the recommended oil type for your 2017 Subaru Legacy? The manufacturer typically suggests using SAE 0W-20 full synthetic oil. This recommendation isn't just a random pick; it's based on extensive testing and engineering to ensure the engine operates at its peak performance and efficiency. Using the recommended oil type ensures that your engine is properly lubricated in various operating conditions, from cold starts to high-temperature drives. The 0W-20 viscosity rating indicates the oil's thickness and flow characteristics at different temperatures. The '0W' part means it has excellent flow even in cold weather, which is crucial for those frosty mornings when you need your engine to start up without a hitch. The '20' part indicates the oil's viscosity at higher temperatures, ensuring it remains thick enough to protect the engine components when things get hot under the hood. Always refer to your owner's manual for the most accurate and up-to-date information. Your owner's manual is like the bible for your car, containing all the specific details and recommendations from the manufacturer. Sticking to the recommended oil type not only optimizes performance but also helps maintain your vehicle's warranty. Using a different oil type could potentially void certain warranty claims, so it's best to play it safe and follow the guidelines provided by Subaru. In addition to the viscosity, make sure the oil meets the API (American Petroleum Institute) standards. Look for the API certification symbol on the oil bottle, which indicates that the oil has been tested and meets the required performance standards for your engine. Regular checks and adherence to these guidelines will ensure your Subaru Legacy continues to deliver reliable performance for years to come.

Synthetic vs. Conventional Oil

Now, let's talk about the age-old debate: synthetic versus conventional oil. For your 2017 Subaru Legacy, synthetic oil is generally the way to go. Why, you ask? Synthetic oils are engineered to provide superior performance and protection compared to conventional oils. They are formulated with highly refined base oils and advanced additives, resulting in better resistance to breakdown, improved high and low-temperature performance, and enhanced engine cleanliness. Conventional oils, on the other hand, are derived directly from crude oil and lack the advanced properties of synthetic oils. While they are cheaper, they don't offer the same level of protection or longevity. Synthetic oils are designed to withstand higher temperatures without breaking down, which is especially important for modern engines that run hotter. They also flow better in cold temperatures, ensuring that your engine is properly lubricated from the moment you start it up. This can significantly reduce wear and tear, especially during cold starts. Another benefit of synthetic oil is its superior resistance to oxidation and sludge formation. Conventional oils tend to break down more quickly, leading to the formation of sludge and deposits that can clog engine components and reduce performance. Synthetic oils maintain their viscosity and cleanliness for longer periods, helping to keep your engine running smoothly and efficiently. While synthetic oil may have a higher upfront cost, its benefits often outweigh the expense in the long run. With synthetic oil, you can typically extend your oil change intervals, meaning you won't have to change your oil as frequently as with conventional oil. This can save you time and money in the long run. Plus, the added protection and performance benefits can help prolong the life of your engine, reducing the risk of costly repairs down the road. For your 2017 Subaru Legacy, investing in synthetic oil is a smart choice that will keep your engine running strong for years to come.

Oil Change Frequency

So, how often should you change the oil in your 2017 Subaru Legacy? A good rule of thumb is to follow the manufacturer's recommendation, which is typically around 6,000 miles or 6 months, whichever comes first, when using synthetic oil. However, this interval can vary depending on your driving habits and conditions. If you frequently drive in severe conditions, such as stop-and-go traffic, extreme temperatures, or dusty environments, you may need to change your oil more frequently. Severe driving conditions can put extra stress on your engine and cause the oil to break down more quickly. In these cases, it's best to err on the side of caution and shorten your oil change interval to around 3,000 to 5,000 miles. Regularly checking your oil level and condition is also essential. Low oil levels can lead to engine damage, while dirty or sludgy oil can reduce performance and increase wear. To check your oil, park your car on a level surface, wait for the engine to cool down, and then remove the dipstick. Wipe it clean, reinsert it, and then remove it again to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick. If the oil level is low, add more oil of the recommended type until it reaches the proper level. Also, take a look at the color and consistency of the oil. Clean oil should be light brown or amber in color. If the oil is dark, sludgy, or contains contaminants, it's time for an oil change. Keeping track of your oil change intervals and regularly monitoring your oil level and condition are crucial for maintaining the health and performance of your engine. Don't neglect this essential maintenance task, and your Subaru Legacy will thank you with years of reliable service.

Choosing the Right Oil Filter

Don't forget about the oil filter! When you're changing your oil, it's just as important to choose the right oil filter for your 2017 Subaru Legacy. The oil filter's job is to remove contaminants and debris from the oil, preventing them from circulating through your engine and causing damage. A high-quality oil filter will effectively trap these particles, keeping your oil clean and your engine running smoothly. There are many different types of oil filters available, ranging from basic, low-cost options to premium, high-performance filters. While it may be tempting to save a few bucks by opting for the cheapest filter, it's generally worth investing in a quality filter that will provide better protection for your engine. Look for oil filters that meet or exceed the original equipment manufacturer (OEM) specifications. OEM filters are designed specifically for your vehicle and are tested to ensure they meet the required performance standards. They typically offer better filtration and durability compared to aftermarket filters. When choosing an oil filter, consider factors such as filtration efficiency, capacity, and durability. A filter with high filtration efficiency will remove more contaminants from the oil, while a filter with high capacity will be able to hold more debris before becoming clogged. A durable filter will withstand the pressure and temperature extremes of your engine without failing. Some oil filters also come with special features, such as anti-drain back valves, which prevent oil from draining back into the engine when it's turned off. This helps to ensure that the engine is properly lubricated upon startup, reducing wear and tear. When in doubt, consult your owner's manual or ask a trusted mechanic for recommendations on the best oil filter for your 2017 Subaru Legacy. Using the right oil filter in combination with the recommended oil type will help keep your engine clean, protected, and running at its best.

Additional Tips for Oil Maintenance

Alright, let's wrap things up with some additional tips to make sure you're on top of your oil maintenance game for your 2017 Subaru Legacy. First off, always use a new drain plug gasket whenever you change your oil. This little gasket helps create a tight seal between the drain plug and the oil pan, preventing leaks. Reusing an old gasket can lead to leaks, which can cause your oil level to drop and potentially damage your engine. Before installing the new oil filter, lightly lubricate the rubber gasket with fresh oil. This will help ensure a good seal and prevent the filter from sticking to the engine. When tightening the oil filter and drain plug, don't overtighten them. Overtightening can damage the threads or crush the gasket, leading to leaks. Use a torque wrench to tighten them to the manufacturer's specified torque. Keep a record of your oil changes, including the date, mileage, and the type of oil and filter used.
