If you want a clean cheap petroleum oil, chainsaw bar oil will work. Generally I prefer the generic Tractor Supply bar oil because it seems a lot stickier than walmart's version which seems more like hydraulic fluid to me. But either way it is cheap because in a chainsaw 95% of it is just sprayed all over the place anyways.
The last time I bought chainsaw bar oil I think it has added sulfur or something like that. I'm not really sure. It's actually worse to work with than used motor oil. Used motor oil starts out clean & is constantly being filtered in a normal motor.
