Had a tree service come on the property to remove some large danger tree's, anyway the tree service uses Wesson's Cooking oil for there bar oil. The owner said he found out that the oil provides the same protection at a quarter of the cost for regular bar oil. He said he has been using it in all his saws for a couple years now and never had a problem, the only issue is, sometimes when its really hot the saw starts smelling like popcorn. Just wondering if anyone has heard of this.
