What kind of oil does a 2015 Crosstrek take?
The 2015 Crosstrek takes SAE 0W-20 full synthetic motor oil.
For the 2015 model year, Subaru's 2.0-liter FB20 engine is designed to run on light-viscosity oil to balance performance and efficiency. Using the recommended oil helps maximize fuel economy, reduce wear, and maintain warranty compliance.
Official specifications for the 2015 Crosstrek
