According to the information I found, the fuel requirements for the Subaru Forester depend on whether the engine is turbocharged or not.
If your Subaru Forester has a non-turbocharged engine, it can run on regular unleaded gasoline with an octane rating of 87. Most Subaru Foresters with a non-turbocharged engine use regular unleaded gasoline with an octane rating of 87.
However, if your Subaru Forester has a turbocharged engine, it is recommended to use premium gasoline with an octane rating of 91 or 93, depending on the model year. Most Subaru Foresters with a turbocharged engine use premium gasoline with an octane rating of 91 or 93.
It’s important to follow the manufacturer’s recommendations for fuel type to ensure optimal performance and avoid potential engine damage.
I hope this information helps! Let me know if you have any other questions.

What kind of gas goes in a Subaru Forester?
The Subaru Forester runs on 95 RON unleaded petrol. Using a lower RON rating may cause engine knocking, while using a higher RON rating may not provide any additional benefits.
Can I use regular gas in Subaru Forester?
Higher octane doesn’t make your Subaru perform better unless it’s required. If you drive a Crosstrek, Forester, Outback, Legacy or Ascent, your vehicle is designed to run on 87 octane, or regular fuel.
Premium gasoline can withstand more excellent compression before combustion, making it essential for some Subaru models like the WRX and BRZ, which have higher compression ratios. Using regular unleaded gas in these cars could lead to premature combustion and potential engine damage.
Can I put unleaded fuel in a car that takes premium? According to Fuel Express, you can put regular gas in your car or truck even if the manufacturer recommends premium. But if they require premium, then pumping unleaded might cause issues.
In most cases, the difference in performance is small and something you may not notice during normal driving. If the car is designed for regular gas — or doesn’t specifically say that the car requires premium gas — go with regular. There are no benefits to putting premium gas in a car that doesn’t need it.
What kind of gas does a Subaru Forester take?
regular 87-octane fuel
For the majority of Subaru models, such as the Crosstrek, Forester, Outback, Legacy, and Ascent, regular 87-octane fuel is perfectly adequate. These vehicles are designed to run efficiently on regular fuel, providing a good balance of performance, fuel economy, and cost savings.
What happens if I put 87 instead of 91?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you’ll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
Can you put regular gas in Subaru XT?
Folks, the Ascent and 2020+ Outback XT (and Outback Wilderness) require 87 octane (or higher) in all climates, at any altitude.
Can you put regular gas in a Subaru?
If your Subaru has standard specifications and does not carry a warning to use only premium gas, regular gasoline should not affect performance. However, if your Subaru engine is turbocharged, follow manufacturer recommendations and use only premium gasoline.
However, the engines found in the Subaru BRZ, the Subaru WRX, and the Subaru WRX STI are built for higher compression with a powerful turbocharger — as a result, regular fuel can be problematic in these engines. Instead, premium gas is required.
