• BP Turbo Oil 2389 is a 3 cSt synthetic lubricant.
• BP Turbo Oil 2389 is approved against US military specification MIL-PRF-7808L grade 3 and
incorporates a level of technology from Type II (5 cSt) commercial turbine lubricants.
Applications & Approvals
• This lubricant combines the thermal and oxidation stability of our commercial 5 cSt synthetic
lubricant, BP Turbo Oil 2380, with the ability to flow at extremely low environmental
temperature. In addition, it has gear-carrying ability equal to or better than other approved MILPRF-7808L Grade 3 oils.
• BP Turbo Oil 2389 thus affords the military operator the lower viscosity advantage of MIL-PRF-
7808L Grade 3 oils while providing the higher quality advantages of the Type II commercial oils,
especially with respect to better thermal and oxidation stability.
• BP Turbo Oil 2389 has been approved by a wide range of engine and accessory manufacturers
for their applicable equipment, including:
Rolls-Royce Ltd, Rolls-Royce Allison, GE, Pratt & Whitney, Pratt & Whitney Canada, Honeywell,
Hamilton Sundstrand, CFMI, MTU, Solar and Turbomeca.
Please contact our local representatives shown in the Air BP website for approval details.
Features & Benefits
• A major advantage of BP Turbo Oil 2389 is its ability to limit the formation of vapor phase
• BP Turbo Oil 2389 provides load carrying ability well in excess of requirements established by
the engine and accessory manufacturers.
• The superior low temperature viscosity of BP Turbo Oil 2389 makes it a better product for low
temperature application. Many APU operators prefer to use 3 cSt oil, such as BP Turbo Oil 2389
for lubrication in order to improve its cold start reliability
