According to the Renewable Fuels Association, 70 percent of all gasoline is blended with ethanol.
The low-level blend E-10 is approved for use under the warranty of every make and model of vehicle sold in the U.S. E-15 is approved for all light duty vehicles model year 2001 or newer.
E-85, a blend of 85 percent ethanol and 15 percent gasoline, can be used only in flex fuel vehicles.
The market potential for mid-level blends is growing. These blends have an ethanol content greater than 10 percent and less than 85 percent. The most common is E20. For now, this mid-range ethanol blend can be used only in flexible fuel vehicles. However, research has shown that higher blends are safe and practical in today’s vehicle fleet.
What are Blender Pumps?
Blender pumps typically utilize two underground tanks, one containing unleaded gasoline and the other containing E85.
In addition to offering more traditional fuels such as unleaded, E10, E15 and E85, the fuel pump can also dispense a variety of mid-level ethanol blends – often E20, E30 and E40 – which are created by mixing the appropriate percentages of fuel from each underground tank.
