Fuel Blends

Blending amounts of alternative fuel with conventional fuel is one way to displace petroleum. Examples of low-level fuel blends include E10 (10% ethanol/90% gasoline), E15 (10.5% to 15% ethanol blended with gasoline), B5 (5% biodiesel/95% diesel), and B2 (2% biodiesel/98% diesel). Blends can also consist of two types of alternative fuels, such as hydrogen and compressed natural gas (HCNG), which can be a combination of 20% hydrogen/80% CNG. B20 (20% biodiesel/80% diesel) and E85 (51% to 83% ethanol blended with gasoline depending on geography and season) are not considered low level blends.
