I have not heard one word about the importance of viscosity.
Why not? You all are more or less professionals. Did this not occur to you?
I switched to Canola Oil for some time but after talking to different engineers from Husky and Stihl I learned that the oil needs to stay on the chain and bar interface in order to be effective as a lubricant. The whole point is to make the chain slide smoothly over the bar groove and to do the same thing with the links on the chain. Yes Canola oil will work but you may see excessive wear on the bar and chain, as well as increased binding in the chain itself, as well as increased use because it (canola oil) has a lighter viscosity.
I agree with Tom's observation about preserving the environment but strongly disagree with his main point of saving a few pennies as the reason to switch. "Stepping over dollars to pick up pennies" is not a part of my philosophy.
Motor oil has greater amounts of sulphur which I have been told will wear out the seals on the saw faster than bar oil. When I was starting out the only thing we used was cases and cases of Pennzoil 20/50.
In spite of all this I still do use Canola oil when working near fish ponds or sensitive areas.
I also believe it is hard to get good info. when talking to factory reps because, after all, they are on the payroll right?

Snarf How do you know that motor oil contains more sulfur than bar oil? Sulfur content is not listed on the msds.
