LUBRICATING OIL, AIRCRAFT TURBINE ENGINE, SYNTHETIC BASE, NATO CODE NUMBER O-156

Organization:

Year: 1997

Abstract: This specification covers three classes of gas turbine engine lubricating oils, primarily used for aircraft engines, which have a nominal viscosity of 5 centistokes at 100°C and which are typically made with neopentyl polyol ester base stocks. This oil is identified by NATO Code Number O-156.
The lubricating oil classed as follows:

Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Air Warfare Center Aircraft Division Code 414100 B120-3, Highway 547, Lakehurst, NJ 08733-5100, by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter. Intended Use: These lubricating oils are intended for use in gas turbine engines and gear boxes for air, sea, and ground mobility equipment. These oils are designed for operation within the approximate bulk oil temperature range of −40 to 204°C (−40 to 400°F). The STD class oil is intended for use in normal performance turbo equipment where concerns about ferrous material (gears and bearings) corrosion induced from extended periods of inoperation in a moist environment is not a concern. The C/I class oil is intended for applications where corrosion inhibition is desired. The HTS class is for use in hot running engine designs where evidence of oil coking and/or oil degradation is noted. All the lubricant classifications are interchangeable and fully compatible with each other; however, mixing across classifications will diminish the added benefits provided by the C/I or HTS oils and the mixture will revert to the STD level of performance.
