There are enough critters, insects, etc. around here to eat the stuff, but, I hardly ever see motor oil streaks when cutting . Besides, It will be used in various locations. I use about 1 quart of motor oil to 4 tanks of gasoline.
New project is, ELECTRIC chainsaw conversion. Got an old 041 sitting is son's garage and, I'm headed that way on the 10th.
Gotta go get and tear down another Chevy Volt battery or 2 and get the modules sold and shipped.
