I've gummed my es bars a couple times in real stringy wood, but haven't lost a bearing yet. Many miles & very little paint on some of them. I peg my oilers, & run old skool saws too. I wanna see the oil fly off the tip. Friction makes heat, & kills moving parts, oil prevents friction, seemed simple enough till EPA got involved.Them old dogs you like Scotty pump some serious oil too. Newer saws are stingy by comparison.
