E85 gas is a high-level combination of ethanol and gasoline that consists of 51 percent to 83 percent ethanol blended with gasoline. It is a fuel that contains gasoline, but also consists of up to about 85% ethanol, a renewable resource which is made from plant materials such as corn, sugar cane, or grasses. E85 is suitable for use in any vehicle designated as a flex-fuel vehicle by the manufacturer. Flex-fuel vehicles (FFVs) are capable of running on any blend of ethanol and gasoline up to 85% ethanol. E85 should only be put in certain vehicles, called flex fuel vehicles (FFVs), which have a fuel delivery system and engine that are designed to use it. E85 is usually a lot cheaper than gasoline, and it can lower your vehicles MPG by up to 25%, but many vehicles only lose 15% to 20% in fuel mileage. E85 is not as widely available in some parts of the United States, and there are over 3,900 E85 stations throughout the country.
In summary, E85 gas is used as an alternative fuel for flex-fuel vehicles that are designed to run on any blend of ethanol and gasoline up to 85% ethanol. It is cheaper than gasoline, but it is not as widely available in some parts of the United States.
