Choosing the right oil for your 2017 Subaru Outback is crucial for maintaining engine health and longevity. This guide will delve into the specifics of the recommended oil type, explaining the importance of using the correct viscosity and type to ensure optimal performance. We'll also address some frequently asked questions to clear up any confusion.
What type of oil does a 2017 Subaru Outback need?
The 2017 Subaru Outback requires 5W-30 oil. Subaru specifically recommends using their Subaru Genuine Oil or an equivalent oil meeting the SAE 5W-30 viscosity grade and API SN or SN Plus certification (or ILSAC GF-5). Using the correct viscosity is critical for proper lubrication across a range of temperatures. The 5W part indicates the oil's performance in cold weather, while the 30 signifies its thickness at operating temperature.
Why is the correct oil viscosity important?
Using the incorrect oil viscosity can lead to several issues:
- Reduced fuel economy: Too thick an oil increases engine friction, leading to higher fuel consumption.
- Increased wear and tear: Too thin an oil provides insufficient lubrication, resulting in increased engine wear.
- Engine damage: In extreme cases, improper oil viscosity can cause significant engine damage.
It's essential to stick to the manufacturer's recommendations to avoid these problems.
What is the difference between API SN and SN Plus?
API (American Petroleum Institute) certifications indicate the oil's quality and performance standards. SN Plus is a newer certification that provides enhanced protection against low-speed pre-ignition (LSPI), a problem that can occur in some engines, especially those with turbochargers or direct injection. While not explicitly stated as a requirement for all 2017 Outback models, using an SN Plus certified oil offers added protection and is generally a safe choice.
Can I use synthetic oil in my 2017 Subaru Outback?
Yes, synthetic oil is perfectly acceptable and even preferred by many for its superior performance characteristics. Synthetic oil offers better protection at both high and low temperatures, leading to improved engine longevity and fuel efficiency. However, ensure it still meets the specified 5W-30 viscosity and API certifications.
How much oil does a 2017 Subaru Outback take?
The exact oil capacity will vary slightly depending on the engine and whether you are doing a simple oil change or a complete engine flush. It's best to consult your owner's manual for the precise amount. Generally, the capacity is around 4.8 to 5.3 quarts. Always double-check your owner's manual.
What are the consequences of using the wrong oil?
Using the wrong oil can have several detrimental consequences, including:
- Reduced engine performance: The engine may run rough or lack power.
- Increased engine wear: This can lead to premature engine failure and costly repairs.
- Voiding your warranty: Using oil that doesn't meet the manufacturer's specifications might void your warranty.
It's always best to err on the side of caution and use the oil specifically recommended by Subaru for your 2017 Outback.
Where can I find the correct oil for my 2017 Subaru Outback?
Subaru dealerships are a reliable source, but you can also find suitable oils at most auto parts stores. When purchasing, be sure to carefully check the labels to ensure the oil meets the required specifications (5W-30, API SN or SN Plus).
This comprehensive guide should help you choose the right oil for your 2017 Subaru Outback. Remember to always consult your owner's manual for the most accurate and up-to-date information. Proper oil maintenance is a key component in keeping your vehicle running smoothly and reliably for years to come.
