No, certainly not.

Visciosity matters, because otherwise it leaks out of most cheap saws
when stored.

Stickiness is useful, to avoid flinging - the oily chain has to go
round a whole bar length and nose pulley before getting anywhere
useful. Flinging thin oil around (why diesel and especially ATF are a
bad idea) also tends to dump it into your face.

I buy the good stuff. It's cheap enough - certainly compared to petrol
and time! If you're really stuck, or you run out, cooking oil is
probably one of the better substitutes. Most oil lubricates, but posh
modern oils continue to lubricate after 100k miles in a hot engine.
Chainsaws are single use total loss, so you just don't have this as an
issue,
