Hello-
I agree that oils should be avoided in lubricating
the 'tron. But, penetrating oils (like WD-40 or
3-In-1) and silicone based oils, should be avoided
completely. Even though they can evaporate, the
solvents in them tend to make things dissolve
unexpectedly, or soften. If the oil gets into a pinch
roller, god knows what could happen to the tape.
Silicones tend to bond to metal and electronics,
changing their characteristics. It is very hard to
completely clean off. Get silicone oil on a circuit
board, and solder repair can be damn near impossible.
If you feel oiling needs to be done, use a pure fine
machine oil, with NO additives.
