MS-8p
OST 38.101163-78
Petroleum-based oil with a package of high-performance additives. It is produced from West-Siberia and Ural petroleum. It has been developed to substitute oils MK-8 and MK-8p, it has superior operating characteristics such as improved viscosity at low temperatures, improved thermal-oxidative stability and life time.
Application field:
It is applicable in gas turbine engines of subsonic and supersonic airplanes (civil aviation airplanes Il-62, Il-76, Tu-134, Tu-154, Yak – 40, military aviation airplanes MiG-21, Su-15, Su-25, helicopters Mi-6, Mi-10) which have oil temperature (at the outcome) up to +150oC.
It is applied as a part of oil mixtures in turboprop engines (airplanes An-12, An-22, An-24, An-30, Il-18) and also for preservation of oil systems of aeroengines. It is also used in ship gas turbine plants and gas pumping aggregations.
