- "Use No Oil" means that when you are dealing with hi pressure oxygen,
- any little thing like a tiny bit of oil seepage can cause an
- explosion. Oxygen is HIGHLY reactive and more so under pressure.
- Technically you might be able to use the gauge for diesel fuel, but I
- would mark the gauge clearly in case it happens to wander out of your
- hands back into use on an oxygen tank.
