WASHINGTON — Reporting prices for higher ethanol blends this summer could again win you $50 in free fuel per day. Beginning Memorial Day, the Renewable Fuels Association is re-launching the "Ethanol Days of Summer" contest, allowing both fuel retailers and consumers to report prices posted for E85 and other higher ethanol blends. To enter, consumers must have a registered account onÂ www.E85prices.com, where they can submit pricing for a chance to win, or post on the mobile app. The RFA website is crowdsourced and offers updated prices for E85, E15, and other ethanol blends from thousands of stations across the country. There are more than 4,200 stations selling E85 across 2,412 cities in the country, and 1,300 stations in 29 states that offer E15. Among other information, E85prices.com contains a nationwide map of all E85 and E15 stations, historical pricing, a public forum to allow consumers to pose questions and discuss various issues, and an ethanol savings calculator, allowing users to see how much money they can save by using various ethanol blends. "This contest was a huge success last year and we expect this year to be even bigger with hundreds of new stations offering higher ethanol blends. E85prices.com is the one-stop online resource to find out where fuel retailers are offering these fuels and what prices have been reported at each particular station," said RFA Vice President of Industry Relations Robert White. "This contest will not only drive traffic to these stations, but it will help RFA maintain the best ethanol station locator website, along with pricing information for those stations. Those that participate may even win some free fuel in the process." This is the second year for the contest. In 2017, more than 4,000 new users registered at E85prices.com, with 97 different contest winners. To participate, no purchase is necessary, and users can submit prices for multiple stations each day. Daily winners will be drawn through Labor Day, and winners will be announced every two weeks.
