Finding ethanol-free gasoline is possible but in some areas might require some effort. Premium grades at certain stations, especially those with a 91 octane rating or higher, are more likely to be ethanol-free. Additionally, directories like Pure Gas can help locate stations offering ethanol-free fuel. Marinas often sell ethanol-free gasoline, as it’s preferred for boats, and small engine repair shops may also know where to find it in your area.
To ensure you’re getting ethanol-free gasoline, it’s important to check the labels on the pumps, ask station attendants, or contact fuel companies directly. Websites and apps that specialize in locating ethanol-free fuel can also be valuable resources.
