Fuel Regulations

Canada: Biodiesel Fuel

In Canada, CAN/CGSB-3.520 establishes specifications for blends of automotive diesel fuel containing low levels of Biodiesel Esters (blends from B1 to B5), Table 1. Most of the requirements mirror those of the automotive diesel fuel specification, CAN/CGSB-3.517. The B1-B5 standard requires that the biodiesel component blended into the fuel meets either ASTM D6751 or EN 14214. A specification for blends with B6 to B20 is being developed.
