Hey guys...I know there are some who fear this stuff will ruin their saws, and maybe they have a right to be worried. As for myself I've head mixed experiences. I cannot say for sure if the veggie bar oil contributed to my lubrication problems with my MS390 or not, but in my MS192T and 025 I have had zero problems with canola. Corn oil is a different story. As long as you use the saw every day and/or purge the tank with clean mineral based oil before you store it more than a week or so you'll be fine. Otherwise the stuff will set up and gum your sprocket so it won't turn and the chain will become stiff. The canola has shown no such tendencies. Now to my problem with the 390. It had a few different issues. First, the oil gallery plug popped out of the casing. I replaced it with a set screw that didn't completely fit and obstructed the oil gallery, so that reduced the oil flow. Also the bar groove had a lot of sawdust in it also obstructing flow. I had used corn oil in there before I knew better. As of now I am still using canola in my 192T and 025, and for the time being running petrleum based stuff in my 390. The 390 seen=ms to be very lean with the oil even in the best of c=situations and I am using either a 24" bar or a 16" bow on it which is at the edge of its capabilities and some may say beyond. As for a cheap source of veggie oil cheap is a relative term, I bet you can find canola at a place like Sysco or Florida Food Service or whoever has a similar outfit in your area, restaurant supply shops for abou $20-25 for a 35lb jug, somewhere between $3.75-$5.50 per gallon. You could also probably use soy or peanut oil. I would not suggest WVO since that has a lot of acid and food particles in it. Make biodiesel or burn that staright!
