BP Turbo Oil 2389 is a 3 cSt syntheticlubricant.BP Turbo Oil 2389 is approved againstUS military specification MIL-PRF-7808 grade 3 and incorporates a level of technology from Type II (5 cSt)commercial turbine lubricants.This lubricant combines the thermal andoxidation stability of our commercial 5 cSt synthetic lubricant, BP Turbo Oil 2380, with the ability to flow atextremely low environmental temperature. In addition, it has gear-carryingability equal to or better than other approvedMILPRF-7808 Grade 3 oils. BP Turbo Oil 2389 thus affords themilitary operator the lower viscosity advantage of MIL-PRF-7808 Grade 3 oils while providing the higher qualityadvantages of the Type II commercial oils, especially with respect to better thermal and oxidation stability.BP Turbo Oil 2389 has a wide range ofAPU applications.BP Turbo Oil 2389 has been approved bya wide range of engine and accessory manufacturers for their applicable equipment, including:Rolls-Royce, GE, Pratt & Whitney,Pratt & Whitney Canada, Pratt & Whitney Aero Power APUs (formallyHamilton Sundstrand) United TechnologiesAerospace Systems (formally Hamilton), Honeywell, CFMI, MTU and Turbomeca.A major advantage of BP Turbo Oil 2389is its ability to limit the formation of vapor phase deposits. BP Turbo Oil 2389 provides loadcarrying ability well in excess of requirements established by the engine and accessory manufacturers.The superior low temperature viscosityof BP Turbo Oil 2389 makes it a better product for low temperature application. Many APU operators preferto use 3 cSt oil, such as BP Turbo Oil 2389 for lubrication in order to improve its cold start reliability.
