Background on E15 fuel
E15 fuel is a gasoline-ethanol blend containing 15% ethanol and 85% gasoline. It is currently available in certain parts of the United States and is becoming more widely available. As a car dealer in New York for 20 years, I have seen a lot of changes in the automotive industry, and the rise of ethanol-blended fuels is one of them.
What is E15 fuel?
E15 is a fuel that is made by blending 15% ethanol with 85% gasoline. Ethanol is a biofuel that is typically made from corn, although it can also be made from other sources such as sugarcane. Ethanol has been used as a fuel additive for many years, but E15 is a newer fuel that has only recently become available.
How is E15 different from other types of fuel?
E15 is different from other types of fuel in several ways. First, it contains a higher percentage of ethanol than most other gasoline-ethanol blends, which typically contain only 10% ethanol. Second, it is not approved for use in all vehicles. Only vehicles that are model year 2001 and newer can use E15. Finally, because ethanol is a biofuel, it has different properties than gasoline. For example, ethanol has a lower energy density than gasoline, which means that vehicles may get lower gas mileage when using E15 compared to regular gasoline.
| Property | E15 Fuel | Regular Gasoline |
|---|---|---|
| Ethanol Content | 15% | 0% |
| Approved for Use in: | Model year 2001 and newer light-duty vehicles | All gasoline-powered vehicles |
| Energy Density | Lower than gasoline | Higher than ethanol |
| Price | Can be lower due to government subsidies for ethanol production | Varies depending on location and market conditions |
Subaru Fuel Recommendations
What Types of Fuel Does Subaru Recommend for Their Vehicles?
Subaru recommends that their vehicles use gasoline with an octane rating of 87 or higher. This is because Subaru engines have high compression ratios, which means they require higher octane fuel to prevent engine knocking and other performance issues. It’s important to note that the recommended octane rating may vary depending on the model and year of your Subaru vehicle. You can find the specific fuel recommendations for your vehicle in the owner’s manual or by contacting a Subaru dealer.
In addition to using the correct octane rating, it’s also important to use gasoline that meets certain specifications. Subaru recommends using gasoline that meets the Top Tier Detergent Gasoline standards, which help keep your engine clean and running smoothly. You can find a list of gasoline brands that meet these standards on the Top Tier website.
What are the Consequences of Using the Wrong Type of Fuel in a Subaru?
Using the wrong type of fuel in your Subaru can lead to a variety of problems, including reduced performance, decreased fuel efficiency, and engine damage. If you use gasoline with an octane rating that is too low, you may experience engine knocking or pinging, which can cause damage to your engine over time. On the other hand, if you use gasoline with an octane rating that is too high, you may not see any immediate negative effects, but you will be paying more for gasoline than necessary.
It’s also important to avoid using gasoline that does not meet the Top Tier standards recommended by Subaru. Gasoline that does not contain enough detergents can cause deposits to form in your engine, leading to decreased performance and fuel efficiency over time.
In summary, it’s important to follow Subaru’s fuel recommendations to keep your vehicle running smoothly and avoid any potential engine problems. Use gasoline with the recommended octane rating and make sure it meets the Top Tier Detergent Gasoline standards.
