What kind of oil does a 2010 Subaru Legacy take?

The 2010 Subaru Legacy takes 5W-30 motor oil. This is the recommended oil type and viscosity for this vehicle according to the manufacturer's specifications.


Detailed Answer


The 2010 Subaru Legacy is a midsize sedan that was part of the fourth generation of the Legacy model line. When it comes to the recommended motor oil, Subaru specifies that the Legacy should use 5W-30 oil. This is a common oil weight for many modern vehicles, as it provides good cold-weather performance while also maintaining proper lubrication at higher operating temperatures.


The "5W-30" designation refers to the oil's viscosity, or thickness. The "5W" part indicates the oil's cold-weather performance, while the "30" denotes the oil's viscosity at normal engine operating temperatures. Using the recommended 5W-30 oil helps ensure the engine receives proper lubrication and protection under a variety of driving conditions.


Oil Change Interval


Subaru recommends changing the oil and filter in a 2010 Legacy every 7,500 miles or 6 months, whichever comes first. This maintenance interval is typical for many modern vehicles and helps keep the engine running smoothly and efficiently.


Oil Capacity



  • The 2010 Subaru Legacy has an oil capacity of 4.4 quarts (4.2 liters).

  • When changing the oil, be sure to use the full 4.4 quarts to refill the system.

  • Using the correct oil type and amount is important for the health and longevity of the engine.


Following Subaru's recommended oil type and maintenance schedule will help ensure your 2010 Legacy runs at its best for many miles to come.
