What kind of gas does a Forester take?
The Subaru Forester, a popular compact SUV, typically requires regular unleaded gasoline with an octane rating of 87. This is the recommended fuel type for the Forester's engine, as specified by the manufacturer.
Fuel Requirements for the Subaru Forester
The Subaru Forester is designed to run on regular unleaded gasoline with an octane rating of 87. This is the minimum octane rating recommended by Subaru for the Forester's engine. Using a higher octane fuel, such as premium (91 or 93 octane), is not necessary and will not provide any additional benefits in terms of performance or fuel efficiency.
It's important to follow the manufacturer's recommendations when it comes to fuel type, as using the wrong fuel can potentially cause damage to the engine over time. Using a lower octane fuel than recommended can lead to engine knocking or pinging, which can be harmful to the engine's components.
Reasons for the Forester's Fuel Recommendation
Subaru designs the Forester's engine to operate efficiently on regular unleaded gasoline. The engine's compression ratio and other factors are optimized for this fuel type, which is the most widely available and cost-effective option for most drivers.
- The Forester's engine is designed to run on regular unleaded gasoline with an octane rating of 87.
- Using a higher octane fuel, such as premium, will not provide any significant performance or fuel economy benefits.
- Using a lower octane fuel than recommended can potentially cause engine damage over time due to knocking or pinging.
In summary, the Subaru Forester is designed to run on regular unleaded gasoline with an octane rating of 87, as specified by the manufacturer. Following this fuel recommendation is important for the long-term health and performance of the Forester's engine.
What happens if you accidentally 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.
Should I use 87 or 91 gas?
The greater the octane number, the greater the fuel's ignition temperature. There is no benefit in using a higher octane fuel than your vehicle's engine needs, doing so is just wasting money. If your engine doesn't knock at regular octane (87), there is nothing to be gained from using a higher octane fuel.
Does my Subaru need premium gas?
On ordinary Subaru family vehicles like the Ascent and Forester, regular gas is all you'll need. 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.

Can you use 89 instead of 87?
If you opt for a higher octane than your manual recommends—say, 89 instead of 87—your car will be perfectly fine. It will not, however, improve your car's mileage or give it any sort of extra performance boost. The only thing it will do is cost you extra money, so don't do this.
What happens if I put 89 instead of 87 in my car?
Adding mid-grade gas to a car that uses 87-octane will waste the extra money put into the tank. 89 gas will not make your car go faster. If a manufacturer recommends premium gas, you can still use 87-octane, but it might cause problems to your car's engine.
What happens if you put the wrong gas in your car?
One of the most severe consequences of using the wrong fuel in your car is engine damage. If you mistakenly fill your diesel car with gasoline or vice versa, the fuel may not ignite correctly, causing engine performance problems.
Can I put 89 gas in my 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.
