Labor Day marked the unofficial end of summer and the official end of the Renewable Fuels Association (RFA) Ethanol Days of Summer Contest.

According to RFA, more than 4,000 new users of E85prices.com registered and helped report prices for higher ethanol blends and conventional fuels during the three-month contest, which offered the chance to win $50 in free fuel per day. In total, there were 98 winners who collectively received $5,000 in free fuel.

“This contest not only helped consumers find higher ethanol blends, but it also highlighted the price discount between ethanol blends and regular unleaded fuel,” said RFA Vice President of Industry Relations Robert White. “For example, users recently reported that nationally on average, E15 had been at a 2.3% discount to unleaded and E85 had been at a 22.1% discount. Through E85prices.com, consumers can also immediately see what stations are their best option by location and historical prices.”

The RFA purchased the crowdsourced E85prices.com in 2014 as a way to bolster consumer engagement in higher blends and enhance data collection capabilities. RFA immediately invested in the website and its mobile app to make the website more user-friendly, but also to include E15. In the future, RFA plans similar efforts to boost the number of users and number of pricing experiences collected.
