as for oil:
I know a guy who guesses 3 to 4 oz/gallon by the clear strip in the side of a quart bottle, and swears that's good enough.
Maybe it is: he seems to get by.
It is amazing what machines can handle. I have seen Amish guys just abuse the ever living crap out of Stihls and they just won't die no matter what horrible things were done or not done to them, yet .... The next guy is worrying about getting synthetic bar oil, soaking chains, cleaning chains and whether a saw will last better on 50:1 or 42:1 or 36:1.
To each his own,
Sam
