Dow Corning ® M Gear Oil Additive saves company $56,700 per year A pulp and paper mill producing 600 tons of paper a day reported that by using Dow Corning ® M Gear Oil Additive in their paper machine gear reducers, they were able to reduce power consumption by about 15 percent, which translated to an annual cost savings of $56,700. When added to premium-grade mineral oil, M Gear Oil Additive reduces metal-to-metal friction, which not only reduces energy consumption, but also prolongs gear life.
