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 -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.
