Oil MS-8p (GOST 38 101163-78) — MS-8P oil was developed to replace MK-8 and MK-8P oils. it significantly exceeds them in a number of performance indicators, in particular, in terms of viscosity at low temperatures, thermal-oxidative stability, and service life.

the most widely used oil-based oil with a complex of highly effective additives. It is produced from West Siberian and a mixture of West Siberian and Priuralsk oils. Designed for gas turbine engines of subsonic and supersonic aircraft, which have an oil temperature at the engine outlet of no more than 150 °C. It is used as a part of MS-20 oil mixtures with aviation oil (in the ratio of 25:75, 50:50 and 75: 25) in turboprop engines, as well as for the preservation of aircraft engine oil systems. Used in shipboard gas turbine installations and gas pumping units.
