AEROSHELL TURBINE OIL 390
AeroShell Turbine Oil 390 is a 3 mm2/s synthetic diester oil incorporating a carefully
selected and balanced combination of additives to improve thermal and oxidation stability
and to increase the load carrying ability of the base oil.
Applications :
- AeroShell Turbine Oil 390 was developed primarily as an improved 3 mm2/s oil for British
turbo-jet engines. AeroShell Turbine Oil 390 is fully approved for a wide range of turbine
engines.
- More recently, because of the low temperature characteristics of AeroShell Turbine Oil
390, there is interest in using this oil in auxiliary power units (APU) in order to overcome the
effects of cold soak. Normal practice is to shut down the APU during cruise, the APU then
experiences cold soak, often prolonged, and when the unit is started there is considerable
difficulty resulting in the unit not coming up to speed in the given time, thus causing a hung
start.
Specifications :
- Approved DEF STAN 91-94
- Analogue to IPM-10, VNII NP 50-1 4f and 4u, and
36Ku-A
- OX-7
