There are characteristics to consider when evaluating
the impact of an oil. " The amount of carbon
deposits formed from oil mist and vapor contact
with hot engine surfaces should be considered,
and so should be the load-carrying ability, which
provides for heavy loads on the bearing systems of
turbine engines, " he says. " Cleanliness with minimum
formation of sludge deposits during severe
operation is also important. In addition, an oil's
resistance to physical or chemical change resulting
from oxidation permits long periods of serve
operation without significant increase in viscosity
or total acidity, the main indicators of oxidation.
Finally, seal wear is essential for the life of engines
with carbon seals, so there should be the lubricant
properties preventing the wear of the carbon at the
carbon seal face. "
As to the current high thermal stability (HTS)
types of oils on the market, Horstink observes
that these are more aggressive to engine seals and
O-rings in the long run. " Therefore, the introduction
of HTS oil compatible O-rings (like Viton-GLT
O-rings) in the engine is highly preferable. This can
either be done via field modification or introduced
by the OEM in factory new engines. HPC oils have
the superior thermal stability and are less aggress
to O-rings and seals, " he concludes.
