Stihl Wrenching
Where I currently work, they used to run drain oil through a coffee filter and then use it as bar oil. One of the oldtimers swore that they never had any problems doing that. That same oldtimer has a "knot" on his laynard that is held together by wire that looks to be a straighten out paper clip.
I find old-timers swear a lot, but...
Pity it's toxic waste... and disgusting to work on saw that have used it.
