Standard Specification for
Mineral Lubricating Oil Used in Steam or Gas Turbines1

This standard is issued under the fixed designation D 4304; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This specification covers mineral oils used in steam and
gas turbine lubrication systems where the performance requirements demand a highly refined mineral base oil compounded
with rust and oxidation inhibitors plus selected additives as
needed to control foam, wear, demulsibility, and so forth.

1.2 This specification is intended to define the properties of
mineral oil-based turbine lubricating oils that are functionally
interchangeable with existing oils of this type, are compatible
with most existing machinery components, and with appropriate field maintenance, will maintain their functional characteristics.

1.3 This specification is intended to define only new lubricating oil before it is installed in the machinery.

1.4 This specification is intended to be used as a guide. It is
possible that oils that do not meet this specification may
perform satisfactorily in some turbines.
