MS-8rk
APPLICATION
The MS-8rk is working preservation oil on the basis of MS-8p with corrosion inhibitor. It is intended for lubrication and preservation of aircraft engines. In comparison with MS-8p, it has the same operation characteristics but its preservation characteristics are much higher. When preserving aeroengine lubrication systems, the protection period is 3 months for MK-8, 1 year for MS-8p and 4-8 years for MS-8rk.
