Fuel Blends

Blending low levels of alternative fuel with conventional fuel is an important option for reducing petroleum consumption.

Examples of low-level fuel blends include E10 (10% ethanol/90% 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. Many fleets are starting to use alternative fuel blends such as these in their fleet vehicles.
