Bio G-3000™ Marine Testimonials

The First National Park on Biodiesel

Mammoth Cave National Park operates two ferries using biodiesel on the Green River."The air quality and environmental improvement benefits make this the fuel of choice."

- Ron Switzer, Superintendent, Mammoth Cave National Park, Bowling Green, KY

Still Satisfied After Four Years

Mammoth Cave National Park uses biodiesel in the ferries, graders, backhoes and lawn mower equipment. The park uses B20, and hopes to increase the percentage in the future."If we hadn't told anyone we're running it, no one would have known the difference."

- Steve Kovar, Facilities Manager, Mammoth Cave National Park, Bowling Green, KY
