Greener Living #45 Biofuels 101, Part 2

Bioethanol is an alcohol-based fuel. A 5% blend of bioethanol can be included in ordinary gas and used by any car in the US that runs on unleaded gas. You may be already using bioethanol-blended gas, as the 5% version is now being sold in the US through unmarked unleaded-gas pumps. Saab and Ford both have a flex-fuel model available, which can run on bioethanol-based fuel or on straight gasoline. If you drive an older model, you can still use biofuel if you are willing to have your car converted to flex-fuel.
