Miller Boat Line has begun using a 10-20 percent biofuel mix in one of its passenger vessels, the William Market, and has plans to eventually use it in all four of its vessels. The biofuel, G2 Diesel, provides 15 percent better fuel economy than traditional diesel and leaves a cleaner wake, protecting Lake Erie and generating fewer harmful emissions. Miller Boat Line has long been the most value-friendly way to travel to Put-in-Bay and the only way to bring vehicles to the island. G2 Diesel, is manufactured by a local company named 11 Good Energy, headquartered in Canton, Ohio. G2 Diesel is made primarily from soybean oil and ethanol and has a distinctly different aroma than traditional diesel when burned: some say it smells like French fries or butterscotch.
