Anyone use used engine oil in place of bar/chain oil? Even in a pinch?
I usually use fresh 30wt or 40wt motor oil. You have to fill the oiler more often, but I've never had the oil holes clog up on the bar that way either. And I've never had a bar or chain overheat or wear out due to friction from using fresh motor oil. Best way to check to see if you're getting oil is just run it up to speed and oint the blade at a flat surface and see if you're flinging oil at it. If so, you're good to go.
I can see where using used motor oil might screw up the bar & chain or clog the holes if it has a lot of metal particles in it; but filtration should clear those out. What WILL kill your bar or chain is dirt, sand and other kinds of grit, or God help you, hitting nails/spikes in the tree, or contacting a stone under a dropped log.
my saw cost too much to save a few cents on real bar oil....
