How Does Ethanol Work?

The amount of ethanol contained in a fuel is usually indicated by the letter E, combined with a number, which signifies its concentration. E10 for instance, is 10 percent alcohol and 90 percent standard gasoline. E85, another common fuel, is 85 percent ethanol.

Octane Power

Octane is the most important fuel property because higher octane levels mean more power and efficiency. Ethanol has a naturally high octane rating of 114, while pure gasoline only has an octane rating of 87. 

As societal standards continue to demand more efficient cars with less greenhouse gas emissions, octane from corn ethanol is an environmentally-friendly and cost-saving source of power. 
 

Saving You Money

Fuel prices are controlled by supply and demand, resulting in unfavorable price spikes. American-made ethanol keeps money in your pocket. 

E15 typically costs 3 to 5 percent less than standard E10 blends. E85 creates even larger saving opportunities.  In today's world of lower gas prices, the savings aren't as obvious but they're still happening!
