Eco Machine oils?

I need to get oil for my chainsaws, and I'd like to use the most eco-friendly one possible. We also have other equipment that needs oil. Unfortunately, the owners manuals all are either unavailable or recommend oils I'm not so sure I want on my trees (in the case of the pruning saw), on the ground, or in our pond - which it seems everything runs down into. We do have Ballistol (non-toxic, eco-friendly gun oil), mineral oil, boiled linseed oil, and quote a selection of kitchen oils - I just don't know what kind of viscosity I'm looking for, in this application, and which oils would stand up to the rigors of homestead machinery. I'm not only talking chainsaws, though. I'm talking about shop tools, as well, and for oiling blades and other metals. Maybe even the tractor(though obviously not inside the engine).

I also make my own saddle soap for leathers, and my own wood/ leather conditioning butters - but, I'm not sure these could be used effectively, for anything beyond blades/ bare metal, on my tools.

Which friendly oils are you using, for this? Are you happy with them? Pros & cons?

Hi Carla;
Check this out for your chainsaws.

Hi, Thomas! Thank you! I actually did read that one, but if felt like it only sort of answered part of my questions...?

How about this:

One potential alternative is the use of environmentally compatible or enviro-friendly oils that are produced from vegetables. To achieve this classification, an oil must be nontoxic and must biodegrade rapidly if spilled. Rapeseed-based (usually called canola) oil is currently the most common environmentally compatible chain-and-bar lubricant.

I use rapeseed oil but I am not a commercial forester and avoid using my chainsaw as much as possible but do use one occasionally. I must have got the idea from somewhere (and despite knowing it has a high smoke point from cooking) I think Paul Stamets might use have mentioned it when he chainsaws trees with oil laced with mushroom spores....could well be wrong though and cant check it now as I lent the book to someone. Regardless it seems to work well.
