I have used motor oil,auto trans oil in my stilh only when I was desperate for bar oil. I can buy a gallon of Stilh bar oil at local John Deere Dealer for $9.95. Really prefer official bar oil. Smokes less,keeps chain cooler, healthy for environment and healthy for me,cause I have to breath that smoke if the wind is coming from the wrong direction.
If your bar oil is creating smoke I wouldn't be worried about the health effects of breathig it, Rather I would be worried about the chain that is getting ready to fly off and take out my leg.
There is NO way that your bar/chain should ever get hot enough to "burn" the oil.
