Iowa drivers raised more than $20,000 for breast cancer research and support services in October during the fourth annual Pink at the Pump campaign, co-sponsored by the Iowa Renewable Fuels Association and Iowa Corn Promotion Board. Seventy-four retail stations donated 3 cents of every gallon of Unleaded 88 sold from Oct. 1 through Oct. 31 to the National Breast Cancer Foundation and the Hormel Institute. Unleaded 88, also known as E15, is a fuel containing 15% ethanol and is approved for use in all 2001 and newer vehicles. “We are thrilled that this year’s Pink at the Pump campaign featured a record number of participating stations and raised a record-breaking amount of funds for such a worthwhile cause,” said IRFA Communications Director Cassidy Walter.
