Aviation oil MS-8p
aviation oil
Description
Oil MS-8p OST 38.01163-78 for gas turbine engines subsonic and supersonic aircraft in which the oil outlet temperature from the engine is not more than 150 ° C.
Applications
Oil MS-8p most widely used oil-based oil with a highly complex additives. Produced from West-Siberian and mixtures West Siberian and the Ural crude oils. Oil MS-8p used in the composition maslosmesey with aviation oil MS-20 (in a ratio of 25:75, 50:50 and 75:25) in turboprop engines, as well as for preserving the oil systems of aircraft engines. Used in the ship’s gas turbines and gas compressor units.
Oil MS-8p designed to replace oils MK-8 and MK 8n, it greatly surpasses them on a number of operational parameters, in particular low temperature toughness, thermal oxidative stability, resource work.
