MS-8p
The oils has a petroleum base with a mixture of high-performance additives. It is produced from the West-Siberian and Ural petroleum. It has been developed to replace the oils: MK-8 and MK-8p, but it has significantly superior operating characteristics such as improved viscosity at low temperatures, improved thermal and oxidation stability and lifetime.
APPLICATION
The MS-8p is used in gas-turbine aircraft engines with outlet temperature of oil up to 150°C (civil aircraft II-62, Il-76, Il-86, Tu-134, Tu-154 and Yak-40, military aircraft MiG-21, Su-15 and Su-25, helicopters Mi-6 and Mi-7). It is used in oil compounds in turboprop engines (An-12, An-30, An-32 and Il-18), and for preserving aeroengine lubrication systems. Besides, MS-8p is used in marine (ship), gas-compressor plant and power plant gas-turbine engines.
