Flatfour,
You are correct. In the USAF, we called it "pickleing oil", but it is officially called Mil-PRF-8188D Preservation Oil.
We don't need it in our model turbine engines as we don't have any carbon seals to protect with an oil film, no labyrinth seals to keep from drying out, no very small chambers and passages and spring loaded ball check valves in our fuel controls that should not get gummed up, etc. that most all the big engines have. Preservation oil also helps prevent bimetallic corrosion.
The vaporization/injector tubes in our engines are a very small bore diameter, and could become plugged if filled with oil. Uneven running and high startup temperatures can result if a tube(s) became plugged. That is why Rei told you not to fill them with oil.
In my humble opinion, if we can lube the bearings early in the start-up process, engine life will be extended. No other preservation is necessary, except to keep it clean, and in a temperature stable, moisture free area.
