Two questions:

1) Treadmill oil seems somewhat more expensive than d-i-y type
Silicone Oil. Are there differences, eg alcohol content? or is it
just a way to make more money?

2) My spray can of Baufix Silicone oil says it's ok to 12/2018. What
harm may be done in using it now?

obviously the latter

none. If oil went off in short order in the can it wouldn't be much use. People have been using 1950s (petroleum derived) engine oil & finding it still as good as it was, though the modern stuff performs a bit better. 1930s engine oil was castor, and is unlikely to be in a good state today, plus it performs badly by modern standards.

I think castor oil - apart from racing - had disappeared in the 1930s.
Mineral oil was first produced in the 1860s, and just kept getting better.

WW1 pilots used have the shits, not because of fear but from the amount
of castor oil they swallowed whilst flying.

Yup. The Rotary engines were 'total loss' . They filled em up every
flight and most got thrown out...

I don't know how true it is, but I heard that whisky helped counteract
the effects and they often flew somewhat merry.
