What kind of oil does the 2015 Subaru Outback use?

The Subaru Outback, which houses a 3.6L engine, uses fully synthetic motor oil for optimal performance. That being said, semi-synthetic motor oil is also a viable option. For best results, Subaru recommends using the SAE 5w-30 viscosity oil. Subaru also recommends changing oils once every 7,000 to 10,000 miles. When changing oils, make sure to consistently stick with the same oil, or at the very least, a similar one. Fully synthetic oils provide a greater degree of protection, efficiency and performance. A motor oil change can be done at home, as these oils can easily be purchased at Walmart or Auto-zone. That being said, it can also be done at an auto-shop or mechanic for a higher price.
