||A unit of volume equal to 42 U.S. gallons.
||Finished motor gasoline not included in the oxygenated or reformulated gasoline categories.
Excludes reformulated gasoline blendstock for oxygenate blending (RBOB)
as well as other blendstock.
|Conventional Gasoline, Ed55 and Lower
||Finished conventional motor gasoline blended with a maximum of 55 volume percent denatured fuel ethanol.
|Conventional Gasoline, Greater than Ed55
||Finished conventional motor gasoline blended with denatured fuel ethanol where the volume percent of denatured fuel ethanol exceeds 55%.
|Distillate Fuel Oil
||A general classification for one of the petroleum fractions produced in conventional
distillation operations. It includes diesel fuels and fuel oils. Products known as No. 1,
No. 2, and No. 4 diesel fuel are used in on-highway diesel engines, such as those in trucks
and automobiles, as well as off-highway engines, such as those in railroad locomotives and
agricultural machinery. Products known as No. 1, No. 2, and No. 4 fuel oils are used primarily
for space heating and electric power generation.
|Finished Motor Gasoline
||A complex mixture of relatively volatile hydrocarbons with or without small quantities of
additives, blended to form a fuel suitable for use in spark-ignition engines. Motor gasoline,
as defined in ASTM Specification D 4814 or Federal Specification VV-G-1690C, is characterized
as having a boiling range of 122 to 158 degrees Fahrenheit at the 10 percent recovery point to
365 to 374 degrees Fahrenheit at the 90 percent recovery point. Motor Gasoline includes
conventional gasoline; all types of oxygenated gasoline, including gasohol; and
reformulated gasoline, but excludes aviation gasoline. Note: Volumetric data on blending
components, such as oxygenates, are not counted in data on finished motor gasoline until
the blending components are blended into the gasoline.
||A light petroleum distillate that is used in space heaters, cook stoves, and water heaters
and is suitable for use as a light source when burned in wick-fed lamps. Kerosene has a
maximum distillation temperature of 400 degrees Fahrenheit at the 10-percent recovery point,
a final boiling point of 572 degrees Fahrenheit, and a minimum flash point of 100 degrees
Fahrenheit. Included are No. 1-K and No. 2-K, the two grades recognized by ASTM Specification
D 3699 as well as all other grades of kerosene called range or stove oil, which have properties
similar to those of No. 1 fuel oil. See Kerosene-Type Jet Fuel.
|Kerosene-Type Jet Fuel
||A kerosene-based product having a maximum distillation temperature of 400 degrees Fahrenheit
at the 10-percent recovery point and a final maximum boiling point of 572 degrees Fahrenheit
and meeting ASTM Specification D 1655 and Military Specifications MIL-T-5624P and MIL-T-83133D
(Grades JP-5 and JP-8). It is used for commercial and military turbojet and turboprop aircraft
Commercial - Kerosene-type jet fuel intended for use in commercial aircraft.
Military - Kerosene-type jet fuel intended for use in military aircraft.
|Petroleum Administration for Defense (PAD) Districts
||Geographic aggregations of the 50 States and the District of Columbia into five districts
by the Petroleum Administration for Defense in 1950. These districts were originally defined
during World War II for purposes of administering oil allocation.
Description and maps of PAD Districts and Refining Districts.
||Parts per million.
||Petroleum products produced at a refinery, natural gas processing plant, or blending plant.
Published production equals production minus input. Negative production will occur when the
amount of a product produced during the reporting period is less than the amount of that same
product that is reprocessed (input) or reclassified to become another product during the same
||An installation that manufactures finished petroleum products from crude oil, unfinished oils,
natural gas liquids, other hydrocarbons, and oxygenates.
|Reformulated (Blended with Alcohol)
||Reformulated gasoline blended with an alcohol component (e.g. fuel ethanol) at a
terminal or refinery to raise the oxygen content.
|Reformulated Gasoline (RFG)
||Finished gasoline formulated for use in motor vehicles, the
composition and properties of which meet the requirements of the reformulated gasoline
regulations promulgated by the U.S. Environmental Protection Agency under Section 211(k)
of the Clean Air Act. It includes gasoline produced to meet or exceed emissions performance
and benzene content standards of federal-program reformulated gasoline even though the gasoline
may not meet all of the composition requirements (e.g. oxygen content) of federal-program
reformulated gasoline. Reformulated gasoline excludes Reformulated Blendstock for Oxygenate
Blending (RBOB) and Gasoline Treated as Blendstock (GTAB). Historical reformulated gasoline
statistics included Oxygenated Fuels Program Reformulated Gasoline (OPRG).
|Residual Fuel Oil
||A general classification for the heavier oils, known as No. 5 and No. 6 fuel oils, that remain
after the distillate fuel oils and lighter hydrocarbons are distilled away in refinery operations.
It conforms to ASTM Specifications D396 and D975 and Federal Specification VV-F-815C.
No. 5, a residual fuel oil of medium viscosity, is also known as Navy Special and is defined in
Military Specification MIL-F-859E, including Amendment 2 (NATO Symbol F-770). It is used in
steam-powered vessels in government service and inshore powerplants. No. 6 fuel oil includes
Bunker C fuel oil and is used for the production of electric power, space heating, vessel
bunkering, and various industrial purposes.
||A yellowish nonmetallic element, sometimes known as "brimstone." It is present at various
levels of concentration in many fossil fuels.
