Schaeffer’s Bar and Chain Lube is a para-synthetic, tacky, heavy-duty oil designed to lubricate chain saw bar and chains, slides and saw guides. Schaeffer’s Bar and Chain Lube rapidly penetrates into the pins and bushings of the chain, offering a strong defense against metal-to-metal contact and chain stretch. Blended with a propriety additive package, Bar and Chain Lube has the detergency needed to minimize and prevent the buildup of pitch, wood resin, sawdust and other deposits on the chain drive sprockets and the blade. Schaeffer’s Bar and Chain Lube is one grade lube for year-round use, eliminating the need to change viscosity grade with temperature change.
