Renewable Lubricants Bio-Pro Bar and Chain oil are readily biodegradable bar and chain oils for any chainsaw that requires a 15W50. This product works great in traditional 2 cycle chainsaws (stihl chainsaws, Oregon chainsaws, Husqvarna chainsaws) or in new electric/battery powered chainsaws (green works chainsaws). The use of petroleum lubricants poses environmental dangers to animals and humans. Leakages, emissions and spillages, when handling petroleum oil will lead to direct pollution of the surroundings and the environment. Bio-Pro oils were developed to ultimately biodegrade when lost into the environment. Bio-Pro oils are very tacky, tough, pitch dissolving lubricants that are recommended for chain saw bars and industrial chains and sprockets including those used in pulp and paper mills, saw mills, plywood mills, and general manufacturing. Other possible uses include chain drives on straddle lift lumber carriers, ATV and motorcycle chains, farm equipment, automatic and hand operated oilers. Meets VGP/EAL requirements.
