Does the Subaru Ascent turbo need premium gas?
The Subaru Ascent, a popular midsize SUV, is known for its spacious interior, advanced safety features, and robust performance. One common question among potential buyers and current owners is whether the Ascent's turbocharged engine requires premium gasoline. In this article, we will explore the fuel requirements for the Subaru Ascent and the implications of using different fuel grades.
Understanding the Subaru Ascent's Engine
The Subaru Ascent is equipped with a 2.4-liter turbocharged four-cylinder engine that delivers a balance of power and efficiency. This engine is designed to provide a smooth driving experience while maintaining good fuel economy. However, the type of fuel you use can significantly impact the vehicle's performance and longevity.
Fuel Requirements for the Subaru Ascent
According to Subaru's official specifications, the Ascent is designed to run on regular unleaded gasoline with an octane rating of 87. This means that while premium gasoline (typically rated at 91 or higher) can be used, it is not necessary for the vehicle's operation. Here are some key points to consider:
- Regular Gasoline is Sufficient: The Ascent's engine is tuned to perform optimally on regular unleaded fuel, making it a cost-effective choice for daily driving.
- Premium Gasoline Benefits: While using premium fuel may provide slight improvements in performance and efficiency, these benefits are often marginal and may not justify the higher cost.
- Engine Knock Prevention: The turbocharged engine is designed to prevent knocking, which is a concern with lower octane fuels. Therefore, using regular gasoline should not lead to engine issues.
Conclusion
In summary, the Subaru Ascent does not require premium gasoline; it is designed to run efficiently on regular unleaded fuel. While premium gasoline can be used, it is generally not necessary and may not provide significant advantages for most drivers. Always refer to your owner's manual for specific recommendations and consult with a trusted mechanic if you have further questions about your vehicle's fuel needs.
Frequently Asked Questions
Are turbo cars better on gas?
Turbochargers are more effective at getting higher power out of smaller engines that, without a turbocharger, might not produce much horsepower. A turbocharger won't improve an engine's fuel economy, but it will get more horsepower out of a smaller, more fuel-efficient engine.
Does the Subaru Ascent need premium gas?
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 is the disadvantage of a turbo engine?
Cons of a turbocharged engine
Affordability: Cars with turbocharged engines are typically more expensive than vehicles with standard engines because may need to use premium gas in your car. Reliability: Turbocharged engines may not be as reliable as standard engines. Engines with more parts have more that can go wrong.
What happens if you put 87 in a turbo Subaru?
You may notice some slight degradation in performance using a lower octane fuel, but the vehicle will automatically adjust engine timing, avoiding a preignition condition. The WRX STI, on the other hand, requires 93 octane.
Do all Subarus require premium gas?
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.

Does turbo engine need premium gas?
By 2019, more than one-third of all cars, SUVs and pickups were equipped with a turbocharger, according to the U.S. Environmental Protection Agency (EPA). Those turbocharged engines are more likely to require high-octane gas than a non-turbo engine.
Does a Subaru turbo need premium gas?
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.
What happens if you put regular gas in a turbo car?
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.
Do all luxury SUVs require premium gas?
Not necessarily. While it's true that many high-end vehicles have high-performance engines, not all of them require or recommend premium fuel.
