Filling up with 85 percent ethanol paid off in a big way for an Indiana couple who hit the Hoosier Lotto jackpot this month.

According to Hoosier Lottery officials, Pamela Smith of Summitville won a $2.5 million jackpot in the May 9 Hoosier Lotto drawing after stopping at a Muncie gas station specifically to buy E85.

“I was looking for Ethanol gas,” said Smith. “I actually went inside the gas station to thank the manager for carrying Ethanol because it’s so hard to find. It was an impulse buy for me to purchase one dollar of Lotto and one dollar of Powerball.”

She and her husband Jay opted for a lump sum payment of nearly $1 million dollars and the retailer received a $25,000 bonus for selling the winning ticket.
