Add me to that camp, the stuff is pure misery to get rid of once you spill some. It's like never-seize, spill a drop on your foot and before you know it your hair is sticky..
I use whatever bar and chain oil I can lay hands on, whether I'm at the Stihl dealer when I remember I need some, or at the hardware store. Both are reasonably priced for what they do.
I'm likely one of the most miserly people you'd come across, not to be confused with cheap. I should qualify that comment, because the difference isn't always apparent..
Definition of miserly: Willing to lie in wait for days, weeks, or months to get the best deal on something that entirely suits my purpose and gives me no trouble. Not to be interfered with whilst on the quest for "the deal of the century" at risk of getting bitten, flailed at, or stepped on.
Definition of cheap: Barely willing to spend very little money on something that might work, needs extensive repair, or is quite likely to make my life living hel*, just because I got a "good deal" on it.
I normally use my saws on weekends, mostly for firewood or clearing wind falls.
Until further notice, each weekend only includes two days, which shall be referred to as "first" and "last". If it's raining on one day, "first" and "last" merge into one day the length of which is measured in "degrees of frenzy".
Did I mention a wife, three cats, two horses, and a hungry wood stove?
I get pretty cranky when either (or God forbid both) of those two days is spent doing repairs that I could have avoided by either getting the right stuff to begin with, or by not straying from "miserly" to "cheap".
Every time I get the urge to be cheap, I ask myself, "Ok self, what is that going to mean on day "xx" late in the afternoon after the stores have closed, and/or you have to drive 50 miles to get parts, which may be on back order until the turn of the century?"
I usually see the light.
Sorry for the ramble, some days I just can't help myself.
