Oregon Gov. Kate Brown has signed into law legislation enabling the sales of 15 percent ethanol blended fuel (E15) in Oregon.

Under current law, Oregon requires that gasoline sold for use in motor vehicles be blended with up to 10 percent ethanol (E10). The new legislation sets 10 percent as a minimum, allowing for sale of fuel with higher concentrations of ethanol. This makes Oregon the 48th state to approve E15.

“Now, we have only two more states that need to take the same action—California and Montana—as well as some key counties in Arizona,” said Renewable Fuels Association president and CEO Geoff Cooper “We will continue to provide technical, regulatory, and legislative assistance as needed so their drivers, too, can drive on E15. We also continue our work in more than a dozen other states to ensure their rules and regulations are clearer and more explicit regarding the approved use of E15.”

E15 is currently offered at over 2,440 retail sites in 30 states and 230 terminals.
