Can you put regular gas in a Subaru Crosstrek?


As a proud owner of a Subaru Crosstrek, you may find yourself wondering about the type of fuel that is best for your vehicle. With years of experience in car maintenance and repair, I’m here to clarify whether using regular gas is a viable option for your Crosstrek.


Understanding Fuel Requirements


The Subaru Crosstrek is designed to run on regular unleaded gasoline with an octane rating of 87. This means that, in most cases, you can safely use regular gas without any adverse effects on your vehicle's performance. However, there are a few important considerations to keep in mind.


Benefits of Using Regular Gas



  • Cost-Effective: Regular gas is typically less expensive than premium fuel, allowing you to save money at the pump.

  • Manufacturer Recommendations: Subaru specifically states that regular unleaded gasoline is acceptable for the Crosstrek, which means you won't void your warranty by using it.

  • Performance: For most driving conditions, regular gas will provide adequate performance and fuel efficiency for your Crosstrek.


When to Consider Premium Gas


While regular gas is suitable for the Crosstrek, there are situations where using premium fuel might be beneficial:



  • High-Performance Driving: If you frequently drive in mountainous areas or engage in high-performance driving, premium gas (with an octane rating of 91 or higher) may help prevent engine knocking.

  • Engine Maintenance: If your vehicle is older or has experienced engine issues, premium fuel can sometimes help improve performance and efficiency.


Conclusion


In summary, you can confidently use regular gas in your Subaru Crosstrek without worrying about damaging your vehicle. However, consider your driving habits and conditions when deciding whether to stick with regular or occasionally opt for premium fuel. Always refer to your owner’s manual for the most accurate information regarding fuel requirements.


Frequently Asked Questions

Can Subaru take regular gas?


If you drive a Crosstrek, Forester, Outback, Legacy or Ascent, your vehicle is designed to run on 87 octane, or regular fuel. Performance Subaru models – the WRX, WRX STI and BRZ – have a premium fuel requirement, but even with those vehicles, check your manual for information on which fuels are appropriate.



Is it okay to mix regular and premium gas?


There's nothing wrong with mixing premium and regular gas in the same tank. In fact, this is how midgrade gas is formulated at the station. Rather than drawing from a separate storage tank for each octane rating, gas pumps actively mix high-octane fuel with lower-octane fuel to create midgrade gas.



What to do if you accidentally put regular gas instead of premium car?


If you put lower octane gas in a car that requires premium, everything will still probably be fine, but you should be concerned about the “probably” part. In older cars, putting a lower octane gas in the tank might cause knocking and pinging and will result in reduced performance.



Can I use regular instead of premium gas?


Should I use regular or premium gas? You should use the type of fuel the vehicle's manufacturer recommends. A vehicle that runs on regular gas will not run any better on premium fuel. Using premium gas in a vehicle designed for premium gas will help the car perform better and avoid damaging the engine with regular gas.
