Many car enthusiasts and everyday drivers are curious about using E85 fuel, a blend of up to 85% ethanol and 15% gasoline. There’s a common misconception that long-term E85 use can harm your vehicle. However, modern vehicles are generally well-equipped to handle ethanol fuels, and E85 can be a beneficial fuel option when used correctly.
Modern fuel systems are designed to withstand ethanol. Even standard gasoline sold at pumps today contains up to 10% ethanol (E10). In fact, there’s a movement towards increasing this percentage to E30 in regular pump gas in some regions. Therefore, the materials used in your car’s fuel lines and other components are typically compatible with ethanol.
However, there are a few key considerations for long-term E85 usage. One important practice is to run a tank of regular pump gas through your system every 3,000 miles or every three months, whichever comes first. This helps to keep the fuel system clean and ensures optimal performance.
Ethanol is hygroscopic, meaning it absorbs moisture from the air. This is why it’s crucial to avoid letting E85 sit in your fuel tank for extended periods, especially in vehicles that are stored or not driven frequently. If you are storing a car with E85, it’s best to keep the tank full to minimize air space and reduce moisture absorption.
Regularly testing your E85 fuel is also a good practice. You can use a simple and affordable ethanol tester, readily available online, to spot-check the ethanol content. Finding a reliable gas station with consistent E85 quality is beneficial; once you find one, try to use the same pump for your E85 fill-ups and continue to spot-check periodically.
In conclusion, E85 is a high-performance fuel that can be safely used in modern vehicles long-term, provided you take a few precautions. By understanding the properties of ethanol and following these simple maintenance steps, you can enjoy the benefits of E85 without worry.
