What is it? Is there a commonly used equivalent, such as
30 weight non-detergent?

Apparently, it's different up here in northern NH. Bar and chain oil
has something mixed in with it which makes it a bit more sticky. The
problem to be solved is this: oil is pumped onto the chain as the
chain leaves the top of the bar in the housing. It has to "stick" to
the chain or else it will get flung off at the tip and won't make it
to the bottom of the bar where the work gets done. Bear in mind that
cutting normally takes place on the bottom of the bar before the chain
re-enters the housing and then goes around the sprocket which also
requires oil.

The logging stores up here sell a different mix for winter and summer.
It is a bit lighter in winter and heavier in summer.
