The national yearly average price of gasoline will rise from $2.13 (in 2016) to $2.49 (almost 17%) in 2017, according to GasBuddy Organization Inc. Americans are estimated to shell out $52 billion more to fill up this year due to an 18% jump in oil prices as a result of the Organization of Petroleum Exporting Countries (OPEC) and other nations reaching an agreement to reduce their output.

This implementation could leave numerous Americans wanting an alternative to the impending steep price tag of gasoline. “E15, which contains 15 percent ethanol, is an even better choice for their wallets, their engines, and the environment,” said Emily Skor, Growth Energy CEO. “That’s why more than 400 stations across 28 states are selling E15, and demand continues to grow.”

Growth Energy, leaders in the national effort to increase awareness of ethanol, has announced that drivers across the U.S. have more than 500 million miles driven on E15, making it the most tested fuel on the road. This number is based on sales and consumption data reported over the past 12 months by major gasoline retailers. E15’s fuel performance, safety, and value have been tested by the U.S. Department of Energy proving that vehicles can run without a problem for up to 120,000 miles. Automakers even approve of its use in nearly three-quarters of new cars.

According to Skor, “ethanol is already in 97% of the gasoline sold in the United States” and works for any vehicle manufactured since 2001. A complete list of flex fuel vehicles is available here.
