Nope, not going to ask who makes it. But if you use oil from a jug, and the jug is marked as "Bar And Chain Oil", is there any difference? All I want is some sticky oil that stays on the bar when the saw is revved up. And cleans the guides. I know you can spend $20 or so for a name-brand like Stihl or Husky, or buy a bottle of private label jazz that will do the job and save the money for a 6-pack of good beer. Thank you.
