LINCOLN, Neb. (AP) — Gov. Dave Heineman and state agricultural leaders are urging Nebraskans to buy E85 fuel the next time they pull up to a gas pump in a flex fuel vehicle.

Heineman touted the blended fuel on Friday during a conference call. E85 is a fuel mix that is 85 percent ethanol and 15 percent unleaded gasoline.

The governor’s office says there are about 180,000 flex fuel vehicles registered in Nebraska. Nebraska is the nation’s second-largest ethanol producer, and is home to 24 ethanol plants that produce nearly 2 billion gallons annually.

The Renewable Fuels Association has developed a “Flex-Fuel Station Locator” app to help drivers locate E85 pumps.
