ExxonMobil Mobil Turbo 319A-2

Subcategory: Fluid; Lubricant

Material Notes:
Mobil Turbo 319A-2 is a fully synthetic lubricant developed to meet the performance requirements of Russian gas turbine aircraft engines which operate on mineral-oil-based lubricants. Formulated from a synthetic hydrocarbon combination of polyalphaolefin (PAO) and hindered ester based stock, Mobil Turbo 319A-2 is fortified with a unique chemical additive system. The resulting product has far superior thermal and oxidation stability than mineral-oil-based lubricants. The ability of Mobil Turbo 319A-2 to resist deterioration and deposit formation allows the potential for extended oil drain intervals and less frequent maintenance. The closely controlled viscosity of Mobil Turbo 319A-2 at -51º C, along with a -60ºC pour point, ensure good low-temperature fluidity, permitting engine starting and lubrication at low temperatures. Mobil Turbo 319A-2 exhibits excellent bulk oil stability at temperatures up to 200º C (392º F). The evaporation rate of Mobil Turbo 319A-2 at high temperatures is significantly lower than mineral-oil-based products, and helps minimize oil consumption. The lubricant has excellent resistance to foaming. Mobil Turbo 319A-2 is compatible with existing seal materials, including F Rubber (Viton A), H Rubber (Buna N), and silicone, as well as 11 metals used in gas turbine construction.

Mobil Turbo 319A-2 is recommended for aircraft gas turbine engines that normally operate on mineral-oil-based lubricants, as well as engines approved to operate on oils meeting the specifications listed below. Mobil Turbo 319A-2 is approved against the following specification of the Russian Central Institute of Aeronatutical Motors (CIAM): IMP-10; MS, 8P, MS-8RK; 36/1 Ku-A; VNII NP 50-1-4f and -4u; B3V and LZ-240; Mobil Turbo 319A-2 also meets U.S. Military Specification MIL-L-6081C, as well as the essential performance requirements of U.S. MIL-L-7808K, Grade 3.
