For the first time, soy-based biodiesel will be available at pumps in Michigan. Wacker Oil & Propane in Manchester, MI, is offering B20, a blend of 20% soy-based biodiesel and 80% petroleum diesel.

A Volkswagen club in the Detroit area has been lobbying the supplier for a B20 pump for quite some time, according to Kim Wacker, spokesperson for the supplier.

“We've had people calling on an almost daily basis,” she says. “Some drive out here from Detroit because they find out they can get about a 40% increase in mileage on their vehicles.”
