What kind of oil does a Subaru Legacy need?

The Subaru Legacy, a popular midsize sedan, requires a specific type of engine oil to maintain optimal performance and longevity. According to the manufacturer's recommendations, the Subaru Legacy should use 0W-20 synthetic oil.


Subaru Legacy Oil Specifications


Subaru recommends using a 0W-20 synthetic oil in the Subaru Legacy. This oil specification is designed to provide excellent cold-weather performance, improved fuel efficiency, and enhanced engine protection. The 0W-20 viscosity rating ensures the oil flows easily at low temperatures, allowing for quick lubrication of critical engine components during startup.


In addition to the viscosity rating, Subaru also specifies that the oil used in the Legacy should meet the following requirements:



  • API (American Petroleum Institute) certification: The oil should be certified as meeting the latest API Service Category, which is currently SN or SN PLUS.

  • ILSAC (International Lubricant Standardization and Approval Committee) GF-6 or later specification.


Using the recommended 0W-20 synthetic oil helps ensure the Subaru Legacy's engine operates at peak efficiency, reduces wear and tear, and maintains optimal fuel economy.


Oil Change Intervals for the Subaru Legacy


Subaru recommends changing the engine oil and filter in the Legacy every 6 months or 6,000 miles, whichever comes first. However, it's important to consult the owner's manual for the most up-to-date maintenance schedule, as intervals may vary depending on driving conditions and the age of the vehicle.


Regularly changing the engine oil in the Subaru Legacy is crucial for maintaining the vehicle's performance, reliability, and longevity. Using the recommended 0W-20 synthetic oil and following the manufacturer's maintenance schedule will help ensure your Subaru Legacy runs smoothly for years to come.
