If the valves are stuck, you should probably bring the instrument in
to a pro for service. If you want to try loosening them yourself,
maybe WD40 will work, but it might take a long time to penetrate, or
might not work at all, or might affect the finish.
But maybe by "stuck" you don't mean stuck, but slow. Then a low
viscosity oil might work as a temporary substitute for valve oil.
Severely hydrotreated sounds horrible? LOL. What about dihydrogen
oxide, would you drink it?
Your gasoline is also severely hydrotreated. This treatment removes
unsaturated compounds, smelly stuff and other pollutants.
Naphtha, not naptha.

It's not a life-or-death 'emergency' - but it got me thinking (not being a >> > musician) what I could use that I had around the house to lubricate the

Unfortunately, I don't have 'sewing machine oil' at home (which googling >> > says works ok). But I do have '3-in-1 household oil'.
The MSDS says 3-in-1 is "Severely Hydrotreated Heavy Naphthenic Oil" (> 97%

Googling some more, I see some people say that 'mineral oil' works (which I
can probably get at a drug store, right?) but before I go farther, I wonder
if anyone here has advice for an easily found substitute for trumpet oil on
a Sunday (i.e., hardware or drug store chemical)?
BTW, this ehow article says to use "lamp oil" and "essential oil" in
addition to "scent oil" and "sewing machine oil". Is it just me or are most
of these oils (with the exception of sewing machine oil) exotic or what? >> > http://www.ehow.com/how_6201749_homemade-trumpet-valve-oil.html
I would stick to the mineral oil. Kerosene based products smell and I doubt >> they are harmless. WD40 is good for cleaning things up, but dries out
quickly. Sewing machine oil would also be a good substitute.
mineral oil is too viscous and makes the valves move slowly
