The volatile corrosion inhibited lubricating oil covered by this specification is intended for use in the preservation of enclosed systems where the volatile components will provide protection above the oil level. It can also be effectively utilized as a contact preservative. This material is not to be used in the preservation of any engine fuel tank or fuel storage tank. A method of diesel engine preservation that has proved satisfactory is the alternate procedure as given in MIL-E-10062E, Engines: Preparation for Shipment and Storage of; 3.11.1.1, 4.3, 3.11.1.1.5, 3.11.1.1.6.1, 3.11.1.1.6.2, and 3.11.1.1.7.1. It is not intended for use as an operational preservative oil and should not be used in applications where elastomeric components are present. It is not effective unless an adequate reservoir of oil can be maintained. A minimum of 5 liters of grade 1 or 8.4 liters of grade 2 oil should be used for each cubic meter (1,000 liters) of volume to be protected (U.S. customary equivalents: 5 fluid ounces of grade 1 or 8 fluid ounces of grade 2 for each cubic foot of volume.)
