I'm interested as well, but from a 10w40 perspective leftover from a 
previous car.

>From https://www.oildepot.ca/what-is-the-viscosity-of-bar-and-chain-oil/ 
and https://www.remodelormove.com/what-viscosity-is-bar-and-chain-oil/ 
it appears bar oil is about 30W, so my first though was gear oil might 
be too thick.

One quote from the first link:

Can Motor Oil Be Used As Bar And Chain Oil?

"Can you take a 30-weight motor oil and use it as a bar and chain oil? 
This is not a good idea. Bar and chain oils have additives called 
“tackifiers”. These additives prevent chainsaw oil from flinging off 
during high-speed operation. The tacky oil clings to the bar and chain 
links to prevent dry operation."

I kept looking and found 
https://toolspulse.com/what-can-i-use-for-chainsaw-bar-oil/ which 
equates ISO weights with SAE weights:

"SAE 30 oil is equivalent to ISO 100 grade bar oils, SAE 40 is identical 
to ISO 150 bar oils..."

The above link also contains a viscosity chart that included SAE gear 
oil, which also appears to be yet another scale, adding to the confusion.

Not an effective response to your question, but perhaps helpful, I have
been using used vegetable cooking oil for my bar lube for quite a few years
and it has worked well. It seems "stickier" than motor oil and does not
tend to fly off as easily.

I read a link on it many years ago and started using it after I started
deep frying turkeys for Thanksgiving and had gallos of the stuff around.
Here are a couple different links about why using vegetable oil:
