1.1 This specification covers four grades of fuel oil made of at least 25 % used lubricating oils. The four grades of fuel are intended for use in various types of fuel-oil-burning industrial equipment and commercial boilers under various climatic and operating conditions. These fuels are not intended for use in residential heaters.

1.1.1 Grades RFC4, RFC5L, RFC5H and RFC6 are used lubricating oil blends of increasing viscosity, with or without middle distillate or residual fuel oil, or both, that are intended for use in industrial burners and commercial boilers equipped to handle these types of fuels. This specification is for applications where Specification D 6448 would not meet the performance or other requirements of the burner or boiler in question.

Note 1—For information on the significance of the terminology and test methods used in this specification, see .

1.2 This specification is for use in contracts for the purchase of fuel oils derived from used lubricating oil and for the guidance of consumers of such fuels. This specification does not address the frequency with which any particular test must be run.

1.3 Nothing in this specification shall preclude observance of national or local regulations which can be more restrictive. In some jurisdictions, used oil is considered a hazardous waste and fuels derived from used oil are required to meet certain criteria before use as a fuel.

Note 2—For U.S. federal requirements imposed on used oil generators, transporters and transfer facilities, reprocessors, marketers, and burners, see U.S. Federal Code 40 CFR 279.

Note 3—The generation and dissipation of static electricity can create problems in the handling of distillate burner fuel oils. For more information on the subject, see Guide D 4865.

1.4 The value stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.


This specification covers four grades of fuel oil made of used lubricating oils. These four grades of fuel are proposed for use in various types of fuel-oil-burning industrial equipment and commercial boilers under various climatic and operating conditions. The four grades of fuel oil covered in this specification are RFC4, RFC5L, RFC5H, and RFC6. The fuel oils shall contain a minimum volume of used lubricating oil-derived products as prescribed herein. The oils shall also be homogeneous consisting primarily of hydrocarbons. The fuel oil shall not contain excessive amounts of organic or inorganic acids, or both, and shall be free of solid or fibrous matter.
