Turbonycoil 321 is based on a petroleum base stock and contains additives to improve the high temperature oxidation stability and prevent wear of gas turbine engines. It has a viscosity of 8 cSt at 50°C.
Turbonycoil 321 has been designed for the lubrication of the majority of gas turbines of Russian design. It can also be used as an anti-corrosion oil in closed circuit (MS-8RK). TURBONUCOIL 321 has been used since the early 1990’s on civil airliners such as Tu-134, Tu-154 and Il-76 with hundreds of thousand flying hours accumulated.
It has been approved by CIAM (Central Institute of Aircraft engines) as an analog to the Russian type MS-8P. It is also approved by OEM Mashproekt for use on industrial & marine gas turbines.
