Maybe....
I mentioned to a friend, an outdoors type naturalist, that I needed to fell a tree behind my workshop. Said I needed to get some bar/chain oil first, or maybe just use some SAE 30wt, as I've heard that works in a pinch.
He glared at me as if I had killed his first born. Told me not to use anything but off the shelf vegetable cooking oil from my local grocery store for my bar, specifically canola oil (I assume it has more of the good cholesterol). He said it's cheaper and biodegradeable. Said no oil is going to break down in the short time before it is flung off the chain and at summer temps it won't gel, so no problems.
Got on the internet and found several references to canola based oils for chainsaws, though not current references.
Found some canola based bar oils made by Stihl and others. Nothing I found references grocery store canola oils.
So my question, has anyone used grocery store grade canola oil as a lubricant for their bar and chain?
