Chainsaw Bar Oil Question

I used to sell a bit of it. It had "anti-sling" additive, whatever that was. Probably something similar to the stuff in that Lucas crap in the little crank sprocket gizmo on the counter at the parts store.

Ours was discontinued. I never had first hand knowledge why. But it was a low volume product and the pushback was already growing against the pollution factor. I wouldn't be surprised if before long all products sold as bar and chain oil will be required to be biodegradable.
