You can put E15 (Unleaded 88) in most cars manufactured after 2000, including flexible-fuel vehicles (FFVs).

However, it is not safe for motorcycles, boats, lawnmowers, or passenger vehicles older than 2001.

Before you pull up to the pump, follow these steps:

• Check Your Owner’s Manual: The U.S. Department of Energy Alternative Fuels Data Center notes that while it is generally EPA-approved for 2001 and newer cars, some manufacturers explicitly forbid it. Always check your manual or driver's side door jamb to ensure the automaker supports it.
• Understand the Fuel: E15 contains 10.5% to 15% ethanol. Because ethanol has a lower energy density than pure gasoline, you may see a slight drop in your miles per gallon (MPG).
• Avoid Small Engines: Never use E15 in off-road equipment, motorcycles, or boats, as the higher ethanol content can severely damage their fuel systems and void warranties.
