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

That'd be in the ballpark, yes. Tricky bit is that here, we have two
"weights", winter and summer (the summer oil is heavier).

Thing is, I've known people that put vegetable or canola oil in their
saws, for cutting moose and such (and no, I'm not kidding).
