National Non-Ethanol Gas Directory

Ethanol attracts water and corrodes older fuel systems. Select your state below to find verified ethanol-free (pure gas) stations for your boat, classic car, or power equipment.

Why Avoid Ethanol?

Most pump gas contains up to 10% ethanol (E10). While fine for modern daily drivers, ethanol is hygroscopic—it absorbs moisture from the air.

In boats, classic cars, and small engines that sit for long periods, this moisture causes "phase separation," leaving a layer of corrosive water/ethanol sludge at the bottom of your tank.

Can't Find Pure Gas?

If you're stuck with E10, you need a stabilizer that actually prevents phase separation.
