Key Terms |
Definition |
Aviation Gasoline (Finished) |
A complex mixture of relatively volatile hydrocarbons with or without small quantities of
additives, blended to form a fuel suitable for use in aviation reciprocating engines. Fuel
specifications are provided in ASTM Specification D 910 and Military Specification MIL-G-5572.
Note: Data on blending components are not counted in data on finished aviation gasoline.
|
Gas Plant Operator |
Any firm, including a gas plant owner, which operates a gas plant and keeps the gas plant records.
A gas plant is a facility in which natural gas liquids are separated from natural gas or in which
natural gas liquids are fractionated or otherwise separated into natural gas liquid products or both.
For the purposes of this survey, gas plant operator data are contained in the refiner categories.
|
Gasoline Grades |
The classification of gasoline by octane ratings. Each type of gasoline (conventional
and reformulated) is classified by three grades - regular, midgrade, and
premium. Note: gasoline sales are reported by grade in accordance with their classification
at the time of sale. In general, automotive octane requirements are lower at high altitudes.
Therefore, in some areas of the United States, such as the Rocky Mountain States, the
octane ratings for the gasoline grades may be 2 or more octane points lower.
|
Kerosene |
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 engines.

and less than or equal to 90. Note: Octane requirements may vary by altitude.
|
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. |

for portable outdoor stoves and portable outdoor heaters.
|
No. 2 Distillate |

(see No. 2 Fuel Oil).
|
No. 2 Diesel Fuel |
A fuel that has distillation temperatures of 500 degrees Fahrenheit at the 10-percent
recovery point and 640 degrees Fahrenheit at the 90-percent recovery point and meets the
specifications defined in ASTM Specification D 975. It is used in high-speed diesel engines
that are generally operated under uniform speed and load conditions,
such as those in railroad locomotives, trucks, and automobiles.
|
No. 2 Fuel Oil (Heating Oil) |
A distillate fuel oil that has a distillation temperature of 640 degrees Fahrenheit
at the 90-percent recovery point and meets the specifications defined in ASTM
Specification D 396. It is used in atomizing type burners for domestic heating
or for moderate capacity commercial/industrial burner units.
|
No. 4 Fuel Oil |
A distillate fuel oil made by blending distillate fuel oil and residual fuel oil stocks.
It conforms with ASTM Specification D 396 or Federal Specification VV-F-815C and is used
extensively in industrial plants and in commercial burner installations that are not
equipped with preheating facilities. It also includes No. 4 diesel fuel used for low-
and medium-speed diesel engines and conforms to ASTM Specification D 975.
|
Other (Conventional) |
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.
|
Oxygenated |
Finished motor gasoline, other than reformulated gasoline, having an oxygen content of
2.7 percent or higher by weight. Includes gasohol. Note: Oxygenated gasoline excludes
oxygenated fuels program reformulated gasoline (OPRG) and reformulated gasoline blendstock
