Flex fuel vehicle.

A flexible-fuel vehiclecommonly called FFV’s or dual-fuel vehicle(colloquially called a flex-fuel vehicle),these automobiles are engineered to run on an ethanol and gasoline blend. Normally gasoline is mixed with either ethanol or methanol fuel, and both fuels are stored in the same common tank.

To know the type of your fuel, search for the gas yellow cap or have a label designating such, also your vehicle may have a flex fuel insignia on the rear (trunk) area. There is the yellow pump handles when refueling at your local retailer. We will discuss about the Ethanol and how its production positively impacts our environment.

1. What is Ethanol?

Ethanol is a clean-burning, high-octane fuel that increases our nation’s fuel supply and is made from a renewable resource we grow right here at home. Ethanol can dramatically help our nation’s use less imported oil through a crop commonly and easily grown in this country- corn.

Ethanol also provides consumers a real energy source. Their common blends are chosen by drivers are E20, E30, all the way up to E85. It included of 85% Ethanol and 15% unleaded gasoline.

The number explains the higher numbers mean increased horsepower and octane; it’s also lower price per gallon of fuel, reduces engine knocking and pinging; keeps engine clean by reducing buildup; prevents gas line from freezing in the winter, burns cleaner by reducing greenhouse gases by as much as 50%. In fact, automakers helps producing 50% of all new vehicles to be ethanol compatible.

2. Why use E85 at all?

There are many reasons, but the biggest draw for the loyalists we’ve met is price: The fuel often is at least 25 percent cheaper than regular gasoline, which is enough to offset the drop in mpg you might see when running on E85. So you’ll have to fill up once or twice more a month, big deal. It’s a wash.

The reasons why fans love it because it’s mostly not gasoline, which means supporting American companies and workers, instead of multinational oil companies and OPEC nations.

As a bonus, if one cares about such things, E85 is better for air quality and the environment— particularly cellulosic ethanol (often made from corn husks and other inedible plants), which carries less greenhouse-gas emissions than corn-based ethanol.


With over 16 million FFV’s currently on the road today, chances are many drivers may not even be aware they own one. Let alone the benefits of using an ethanol blend. With styles ranging from sports utility vehicles to sedans, there are many options available on the market.We can find them at more than 3200 retail locations offering ethanol blends across the US.
