What kind of oil does a Subaru Forester XT take?

The Subaru Forester XT, a turbocharged version of the popular Forester SUV, requires a specific type of engine oil to ensure optimal performance and longevity. According to Subaru's recommendations, the Forester XT should use a 5W-30 synthetic oil. This oil grade provides the necessary lubrication and protection for the turbocharged engine, which operates under higher temperatures and pressures compared to naturally aspirated engines.


Subaru Forester XT Engine Oil Specifications


The Subaru Forester XT is equipped with a 2.4-liter turbocharged Boxer engine, which has unique oil requirements compared to other Forester models. Subaru recommends the following engine oil specifications for the Forester XT:



  • Oil Grade: 5W-30 synthetic oil

  • Oil Capacity: 4.4 quarts (4.2 liters)

  • Oil Change Interval: 6 months or 6,000 miles, whichever comes first


It's important to use a high-quality 5W-30 synthetic oil that meets Subaru's specifications to ensure the engine's longevity and optimal performance. Using the wrong oil type or grade can lead to increased wear, reduced fuel efficiency, and even engine damage over time.


Why 5W-30 Synthetic Oil?


Subaru recommends a 5W-30 synthetic oil for the Forester XT for several reasons:



  • Viscosity: The 5W-30 viscosity provides the necessary lubrication and protection for the turbocharged engine, which operates at higher temperatures and under increased stress compared to naturally aspirated engines.

  • Synthetic Formulation: Synthetic oils are engineered to provide superior performance, better resistance to thermal breakdown, and improved fuel efficiency compared to conventional mineral-based oils.

  • Turbocharged Engine Compatibility: The Forester XT's turbocharged engine requires a more robust oil that can withstand the higher temperatures and pressures associated with forced induction. Synthetic 5W-30 oil is better suited for these demands.li>

By using the recommended 5W-30 synthetic oil, Forester XT owners can ensure their vehicle's engine receives the proper lubrication and protection, helping to extend its lifespan and maintain optimal performance.
