Subaru Forester Gas Types: Should You Use Regular or Premium Fuel?

If you own a Subaru Forester or are planning to buy one, one essential aspect you must consider is the type of gas that you use to fuel it. As with most vehicles, using the right type of fuel for your Subaru Forester is crucial for its longevity and performance. In this article, we will guide you through all you need to know about the gas types that are best suited for your Subaru Forester, regular and premium, and their benefits and drawbacks.

Types of Gas Recommended for Subaru Forester

Subaru Foresters are specifically designed to use fuel with an 87 octane rating or higher. Therefore, both regular and premium gas types meet the standards set for the car’s engine. However, while both types of gasoline are appropriate, there are differences between them that are worth noting.

Regular Gas vs. Premium Gas: What’s the Difference?

An essential factor to consider when choosing the right type of fuel for your vehicle is the octane rating. This rating indicates the gasoline’s ability to resist engine knocking or pinging during combustion. Regular gasoline typically has an octane rating of 87, while premium gasoline has an octane rating of 91 or above.

While both regular and premium gas can power your Subaru Forester, premium gas will undoubtedly give you better performance. As premium gas has a higher octane rating, it provides a cleaner burn, reducing the possibility of engine knocking or pinging. On the other hand, while regular gas may still power your car, the likelihood of pinging or engine knocking is higher, which can be harmful to your engine over time.

Benefits of Using Premium Gas in Subaru Forester

Subaru Forester owners should consider using premium gas due to its advantages. These benefits are as follows:

Better Fuel Efficiency

Premium gas can provide better fuel efficiency and translate to better gas mileage for your Subaru Forester. While it may be a bit more expensive than regular gas, the increased fuel efficiency offered by premium gasoline typically offsets the cost.

Improved Engine Performance

Premium gasoline can improve engine performance as it increases horsepower and engine responsiveness. Furthermore, it prolongs the life of the engine through cleaner combustion.

Prevents Engine Build-Up

Premium gas contains additional detergents that help to keep your engine clean from build-up over time. With regular gas, dirt and debris could clog your engine, leading to engine damage over time.

Drawbacks of Using Regular Gas in Subaru Forester

One significant drawback of using regular gas in your Subaru Forester is that it can lead to engine wear and tear over time. This wear and tear are caused by engine knocking or pinging, which happens because regular gas is less efficient. A chemical reaction will occur within the engine, which eventually harms the engine’s internal components.
