 . . . just use kerosene.  Piston valve oil is almost totally kerosene, with each company adding things to slow evaporation or whatever.
Those trumpet geeks had a really nice ITG Journal article back in 1997 (I think) that was a comparison between various oils, both petroleum distillates and polymers.  It was very interesting, in an oily, trumpet kind of way.  (Heh, heh, heh.)
I think that kerosene was used as a control.  But I am probably wrong about this.
