When it comes to fueling your Subaru, understanding the differences between regular and premium gasoline is crucial for both performance and efficiency. Subaru has specific recommendations based on the engine type and model of your vehicle. This article will explore the fuel options available for Subaru vehicles and what the manufacturer advises for optimal performance.
Understanding Fuel Types
Gasoline comes in various grades, primarily categorized by their octane ratings. The two most common types are:
- Regular unleaded: Typically has an octane rating of 87.
