State Petroleum Fuel Specifications

AFPM supports the orderly evolution and use of cleaner-burning fuels to reflect public health and environmental concerns and to provide adequate transportation fuel supplies to the motoring public. This can only be achieved, however, if energy and environmental policymaking is integrated and if the costs and benefits of new regulatory requirements are carefully weighed in the context of their impacts on energy supplies.

The petroleum industry complies with a number of federal and state gasoline and diesel specifications, as well as a few state home heating oil sulfur standards.

The federal programs include year-round reformulated gasoline (RFG) and summer Phase II RVP (Reid vapor pressure).

The state programs include a number of seasonal state regulations, including summer RVP and winter oxygenated gasoline. In addition, several states have year-round statewide gasoline programs including California RFG and oxygenated gasoline in Hawaii, Minnesota, Missouri and Oregon. There are also some local requirements, such as year-round Arizona Cleaner-burning Gasoline in Phoenix.

A number of federal and state diesel fuel standards exist. Currently, there are state diesel fuel specifications applicable in California, Phoenix, and eastern and central Texas.

Minnesota, Oregon and Washington require both ethanol in gasoline and biodiesel in highway diesel fuel. Hawaii and Missouri currently require ethanol in gasoline. Pennsylvania requires biodiesel in highway diesel. States that require ethanol in gasoline and biodiesel in highway diesel fuel with future effective dates include Florida, Louisiana, Massachusetts, Montana and New Mexico.
