What type of fuel should I use in my Subaru?

Subaru vehicles are designed to run on regular unleaded gasoline with an octane rating of 87 or higher. While premium fuel is not required, it may enhance performance for certain Subaru models. However, using a higher octane fuel does not necessarily translate into improved fuel efficiency. It is recommended to refer to the owner's manual or fuel filler door for specific fuel requirements of your Subaru model. Additionally, using non-approved fuels like E85 or diesel is strongly discouraged, as it may cause significant damage to the engine and void warranty coverage. To maintain optimal performance and longevity, it is essential to stick to the appropriate fuel type and follow the manufacturer's guidelines.
