1.1 This specification covers the establishment of requirements of automotive fuels for ground vehicles equipped with spark-ignition engines. 1.2 This specification describes various characteristics of automotive fuels for use over a wide range of operating conditions. It provides for a variation of the volatility and water tolerance of automotive fuel in accordance with seasonal climatic changes at the locality where the fuel is used. For the period May 1 through Sept. 15, the maximum vapor pressure limits issued by the United States (U.S.) Environmental Protection Agency (EPA) are specified for each geographical area except Alaska and Hawaii. Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1. This specification neither necessarily includes all types of fuels that are satisfactory for automotive vehicles, nor necessarily excludes fuels that can perform unsatisfactorily under certain operating conditions or in certain equipment. The significance of each of the properties of this specification is shown in Appendix X1. 1.3 The spark-ignition engine fuels covered in this specification are gasoline and its blends with oxygenates, such as alcohols and ethers. This specification does not apply to fuels that contain an oxygenate as the primary component, such as Fuel Methanol (M85). The concentrations and types of oxygenates are not specifically limited in this specification. However, depending on oxygenate type, as oxygenate content increases above some threshold level, the likelihood for vehicle problems also increases. The composition of both unleaded and leaded fuel is limited by economic, legal, and technical consideration, but their properties, including volatility, are defined by this specification. In addition, the composition of unleaded fuel is subject to the rules, regulations, and Clean Air Act waivers of the U.S. Environmental Protection Agency (EPA). With regard to fuel properties, including volatility, this specification can be more or less restrictive than the EPA rules, regulations, and waivers. Refer to 1.4 This specification does not address the emission characteristics of reformulated spark-ignition engine fuel. Reformulated spark-ignition engine fuel is required in some areas to lower emissions from automotive vehicles, and its characteristics are described in the research report on reformulated spark-ignition engine fuel.2 However, in addition to the legal requirements found in this research report, reformulated spark-ignition engine fuel should meet the performance requirements found in this specification. 1.5 This specification represents a description of automotive fuel as of the date of publication. The specification is under continuous review, which can result in revisions based on changes in fuel, automotive requirements, or test methods, or a combination thereof. All users of this specification, therefore, should refer to the latest edition. 1.6 Tests applicable to gasoline are
not necessarily applicable to its blends with oxygenates.
Consequently, the type of fuel under consideration must first be
identified in order to select applicable tests. Test Method D4815
provides a procedure for determining oxygenate concentration in
mass percent. Test Method D4815 also includes procedures for
calculating mass oxygen content and oxygenate concentration in
volume percent. 1.7 The following applies to all
specified limits in this standard: For purposes of determining
conformance with these specifications, an observed value or a
calculated value shall be rounded “to the nearest unit” in the
right-most significant digit used in expressing the specification
limit, in accordance with the rounding method of Practice E29. For
a specification limit expressed as an integer, a trailing zero is
significant only if the decimal point is specified. For a specified
limit expressed as an integer, and the right-most digit is
non-zero, the right-most digit is significant without a decimal
point being specified. This convention applies to specified limits
in Tables 1, 3, and 1.8 The values stated in SI units
are the standard, except when other units are specified by U.S.
federal regulation. Values given in parentheses are provided for
information only.
1.9 This standard does not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
