TURBO OIL 2380
TURBINE ENGINE & ACCESSORY

Introduction
While the changing of our label for turbo oil is relatively new, our experience in lubricating turbine engines is not. In 1949 the Research Division, which was initially responsible for the development of our turbo oils, helped turn the vision of gas turbine powered flight into the reality we accept for granted today. By developing the first synthetic oil that could be used successfully in gas turbine engines, much wider fields to the aircraft designer were opened. This position of leadership has never been relinquished and you can depend on us just as you did in 1949.

BPTO 2380
BP Turbo Oil (BPTO) 2380, available throughout the world, is now being used by over 350 airlines representing a majority of the free world’s commercial airline requirement for 5 cSt turbo oils. This fact attests to the outstanding performance of this product in the wide variety of engines and accessories now in service.

Product Description
BPTO 2380 is a synthetic oil having a viscosity of 5 centistokes at 210°F that is approved against US military specification MIL-PRF-23699F-STD, DEF STAN 91-101/2* (DERD 2499), and meets the requirements of most jet engines and associated accessories. It is a Type II oil which provides a more balanced combination of thermal and oxidation stability, load-carrying capacity, lower volatility and low temperature flow characteristics than other 5 cSt jet engine oils. These features provide long trouble-free performance under most conditions. Synthetic oils of this type are not all identical. The performance advantages of BPTO 2380 are achieved by careful selection and balance of basestocks and additives to provide the desired performance. Details of laboratory analyses of physical, chemical, and performance properties are provided in the Appendix. Significant performance properties are discussed below. Where detailed information on the laboratory test methods and the significance of results is desired, a member of our BP technical staff will be happy to provide them. VISCOSITY: While most Type II synthetic turbo oils have essentially the same viscosity at 99°C (between 5 and 5.5 centistokes), BPTO 2380 is less viscous at very cold temperatures than other Type II oils. This offers a distinct advantage, which permits BPTO 2380 to be used in some critical applications where other Type II oils are excessively viscous. For example, at -40°C the viscosity of BPTO 2380 is well below that of competitive products. BPTO 2380

LOAD CARRYING: BPTO 2380 provides load carrying ability, as measured in the Ryder Gear Test well in excess of requirements established by the engine and equipment manufacturers. Long life of bearings, gears, and other highly loaded lubricated surfaces is thus assured under normal operating conditions. CLEANLINESS: Minimum formation of varnish or sludge deposits is one of the characteristic advantages of BPTO 2380. Long periods of operation are possible without the danger of scavenge pump screen plugging or the corrosion that often accompanies excessive deposits. BULK STABILITY (resistance to physical or chemical change resulting from oxidation): The high degree of oxidation resistance of BPTO 2380 permits long periods of operation without significant increase in viscosity or total acidity, the two principal indicators of product oxidation. The need to change oil because of oxidation effects is rare when using BPTO 2380. Most users find it unnecessary to make oil changes in spite of occasional mechanical abnormalities that create unusually severe oxidizing conditions. COMPATIBILITY: While considerable laboratory data is available to demonstrate the compatability of BPTO 2380 with metals, elastomers and other lubricants, the extensive airline experience most adequately demonstrates this property. Details are given in the section on “Product Performance.” SEAL WEAR: Proper functioning of carbon seals is essential for the life of the engines that use this type of bearing compartment sealing arrangement. Poor seal performance may be caused by lubricant properties that promote (or fail to prevent) wear of the carbon at the carbon-to-steel face. BPTO 2380 has provided the dependable performance in numerous airlines that was predicted by extensive laboratory tests.

VAPOR PHASE DEPOSITS: A major advantage of BPTO 2380 is its ability to limit vapor-phase deposits. With some competitive oils, heavy deposits have formed where the oil mist and vapors come in contact with hot engine surfaces resulting in migrating deposits.

* BPTO 2380 is approved against DEF STAN 91-101/2 (DERD 2499) for both OX-27 and OX-28 requirements. OX-27 is for use in military gas turbines and accessories. OX-28 is for use in marine gas turbines.

Product Performance
AIRLINE SERVICE: The fact that BPTO 2380 represents the majority of the free world requirement for 5 cSt turbo oils speaks highly of its performance. Over 350 airlines are now accumulating approximately 50 million engine hours a year on this lubricant. Outstanding bulk stability, excellent cleanliness, as evidenced by low deposit levels in vapor phase areas, and very good anti-corrosion qualities have made BPTO 2380 the leader in gas turbine lubrication. OIL CONSUMPTION: Typical consumption with BPTO 2380 ranges from a low of 0.07 litres (0.06 quarts) per engine hour to a high of 0.59 (0.62). Evaporation loss—though a factor—is a minor one. Based upon laboratory tests, BPTO 2380 has a directional advantage in this respect.
Evaporation Loss, % at 61⁄2 hours at 400°F, Sea Level at 400°F, 40,000 ft. at 450°F, Sea Level at 450°F, 40,000 ft.

COMPATIBILITY BPTO 2380 is compatible with other turbo oils meeting the same specifications to the extent that an inadvertent mixing or emergency top-off with another approved brand will not cause additive separation to occur. However, most engine builders do not recommend indiscriminate mixing of approved oils and we agree with this principle. BPTO 2380 performance is outstanding in the critical area of compatibility with elastomers such as those used in O-ring seals. Excessive swelling or shrinking of seals can cause severe oil leakage. In new engines or in high-time engines where BPTO 2380 has replaced another lubricant, there has been no known incident of oil leakage due to oil-elastomer incompatibility. Deposit washing is a problem with some turbo oils. This is the situation where engine deposits, laid down by a previous oil, can sometimes be loosened or washed off by changing to a different oil. The loosened deposits can plug filter screens, which seriously reduces oil flow. This is more apt to occur when changing over high-time engines where deposits have had a chance to dry out during short-term storage or deactivation for service or repair. Laboratory tests and many years of service have shown that changing engines to BPTO 2380 should cause no concern about deposit loosening and migration, under normal circumstances. SHELF LIFE The shelf life of BPTO 2380 can extend beyond four years when stored in original, unopened quart cans under acceptable conditions, such as away from extreme heat and moisture. Likewise, drummed product (includes 55 gallon drum and 5 gallon pails) has an expected shelf life of three years minimum. For all package styles, shelf life can be increased significantly beyond those stated above, depending upon storage conditions. Please contact your bp representative if you have any questions about product usability.

In actual practice, the data suggest that engines cannot distinguish differences in consumption among various Type II oils. Experience in monitoring oil consumption over long periods indicates that: a. Oil consumption is governed more by mechanical factors than by differences between oils of similar type. b. The principal factor related to lubricant chemistry that affects oil consumption is volatility or loss by evaporation and this effect is minor. c. Large differences in consumption among airlines operating identical equipment in similar route structures with the same oil are generally attributed to differences in methods of data collection and record keeping.

Technical Service
BP provides technical service in support of our products and their performance. The two vital elements of this service consist of a highly qualified Technical Staff and a complex of Sales Service Laboratories. As the name implies, the Technical Staff maintains contact with customers, engine and airframe manufacturers, and accessory equipment manufacturers. The Sales Service Laboratories provide laboratory services to assist in used oil analyses. TECHNICAL STAFF The Technical Staff consists of aviation career specialists to provide service to customers and to work with major airframe and engine builders. These specialists have at their disposal the full facilities of Sales Service Laboratories and BP product research facilities. This system ensures that each individual is well informed on equipment developments, industry problems and product performance. Thus, while only one member of the Technical Staff will be the principal contact with a customer, that member will reflect the experience and knowledge of the entire organization and will have ready access to all facilities of the corporation for assistance as required on behalf of his assigned accounts. The fact that the Technical Staff is part of the headquarters of their respective organizations assures that the staff members have headquarters’ authority to assist in effective handling of their assignments . BP provides worldwide technical service in support of turbo oil customers. Service is coordinated by Air BP Lubricants from its office in Parsippany, New Jersey. SALES SERVICE LABORATORIES The Sales Service Laboratories are located throughout the world at BP’s major refineries and blending plants. These laboratories in turn are backed up by the full facilities of BP research facilities in Naperville, Illinois. PRODUCT SAMPLE PROCEDURES AND HANDLING The base purpose of analyzing product samples is to assist in solving or defining a problem that may be related to the performance of the lubricant. Thus, the sample size and handling procedures may vary with the nature of the suspected problem and with the analytical techniques required for definition and solution. Experience has provided standardized procedures applicable in many instances. Details are available from a member of the Technical Staff.

Quality Control
BPTO 2380 is blended in batches with each batch composed of the identical chemicals, in the same proportions, used in all previous batches. Approximately 25 tests are performed on each batch to evaluate the physical, chemical and performance characteristics of the product. Historically, the batch-to-batch variations are within the limits of test repeatability. As each batch is prepared, a quantity of product is set aside in sealed containers. Periodically, a container is opened and tested to ensure that no change has occurred in the physical or chemical properties as a result of time. Customers can enhance the product storage stability life by using first-in, first-out inventory procedures and maintaining the oil under normal storage conditions (indoors protected from excessive heat). Within these parameters, experience has shown BPTO 2380 shelf life has no effect on its performance. It is suggested that oil that has been exposed to extremes of high temperature and humidity in storage be retested. Most important in monitoring product quality is the frequent observation of airline engines and accessories. A specialized rating system has been developed by the Technical Staff in cooperation with the product research facilities. This system provides for numerical descriptions of engine mechanical condition and lubricant performance for all critical lubricated components. By this means, the conditions of two or more engines can be compared even though they may be inspected at different times. The system thus provides a yardstick for measuring the uniformity of performance in operating engines. This method of documentation also permits an appraisal of engine mechanical condition, an evaluation of the effectiveness of mechanical modifications and a comparison of the performance of different lubricants.

Future Outlook
As documented in previous sections, BPTO 2380 is providing outstanding performance in current equipment including the Boeing 707, 717, 727, 737, 747, 757, 767, 777; McDonnell Douglas DC8, DC9, DC10, MD11, MD90; Lockheed L-1011 and the Airbus A300, A310, A320, A330, A340. Based on this background there is good evidence that BPTO 2380 will continue to satisfy the requirements of airline equipment for many more years despite increasing TBO’s and HSI intervals.

While the outlook for continuing excellent performance from BPTO 2380 is bright, our research continues to develop and evaluate new oils aimed at providing even greater value to the world’s airlines. Through continuing monitoring of product performance and technological developments, our affiliates anticipate being able to provide synthetic turbo oils that will satisfy the most critical needs of the aviation industry.

You can protect yourself from routine turbo oil-related hazards by using appropriate engineering controls and work practices, and by wearing proper eye protection, gloves and clothing. Additional important health and safety information for this product is provided on the MSDS, which is available from your BP representative. The exposure guidelines found on the MSDS should always be followed. Turbo oil should never be siphoned by mouth. However, if the oil is swallowed, DO NOT induce vomiting, but seek medical advice immediately to guard against the hazard of aspirating oil into the lungs. While the oil is not highly toxic when swallowed, lung aspiration can result in chemical pneumonia that may not occur for some time. In the event of fire or leakage of product onto an extremely hot surface which causes turbo oil to burn, emission of fumes and combustion products that are potentially irritating, noxious, and toxic may occur, such as aldehydes and carbon monoxide. Take precautions to avoid and/or minimize exposure under these conditions. Use supplied oxygen if necessary. Additional health and safety information may be obtained by writing to: Air BP Lubricants, Air BP, Maple Plaza II-1N, Six Campus Drive, Parsippany, NJ 07054.

Health and Safety Precautions
Health studies have shown that under normal conditions of use, turbo oil presents a low risk to human health. The major health risk from exposure to turbo oil is temporary irritation of the eyes, skin, and respiratory tract. Temporary irritation is a common hazard of most petroleum hydrocarbons and synthetic lubricants, like turbo oil. Irritation occurs when product is applied directly to the eyes, repeatedly to the skin, or when high levels of vapors or mist are inhaled. Because sensitivity to irritation can vary from person to person, direct contact with the eyes and skin, and inhalation of vapors or mist should be minimized. Prolonged and repeated skin contact with turbo oil can also cause temporary dermatitis. Because the vapor pressure of turbo oil is very low, generation of vapor under ambient temperature conditions is unlikely. At elevated temperatures, however, product vapor may be generated at concentration levels sufficient to cause irritation, particularly in poorly ventilated areas or in confined spaces. If this occurs, or if a mist of turbo oil is generated, precautions should be taken to avoid inhaling vapor or mist at concentrations above the exposure guidelines specified on the product Material Safety Data Sheet (MSDS). Prolonged over-exposure to vapors or mist could cause headache, light-headedness, dizziness, and potentially unconsciousness, but normal conditions of use will not produce these effects.
