Mobil Turbo 319A-2

Synthetic Aircraft-Type Gas Turbine Lubricant

Description

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 -51? C, along with a -60?C 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 200? C (392? 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.

Features and Benefits

Mobil Turbo 319A-2 offers the following advantages and benefits:

  • Low evaporation loss and oil consumption
  • Reduced sludge and carbon deposits
  • Improved bulk oil oxidation stability and extended oil drain intervals
  • Compatible with existing seal materials
  • Reduced engine maintenance, including potential for extended drain intervals

Applications

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
