MS-8rk aviation oil
MS-8rk is produces from Russian components in accordance with the TU 38.1011181-88 standard. The MS-8rk oil is made from a special deep-refined base with antioxidant, antiwear and anticorrosive additives.
The MS-8rk oil is intended for aircraft engines lubricating and conservation. Equal to the MS-8p oil with regard to the performance criteria, MS-8rk by far exceeds it in point of conservation properties. The aircraft engine oiling systems conservation period is equal to 3 months when using the MK-8 oil, to 1 year in the case of the MS-8p oil, and increases to 4-8 years with the MS-8rk oil.
Packaging of MS-8rk
MP-8rk oil is supplied to consumers in cans with a capacity of 18 liters, 15.0 kg net each. By agreement with the consumer, it is possible to use other containers of different capacities, including steel drums.
The guaranteed shelf life of MS-8rk oil is 5 years from the date of manufacture.
