A study cited in Machinery Lubrication magazine1 implied synthetic lubricants make gears more efficient than mineral oils. A polyglycol showed the highest efficiency (18 percent more than the highperforming mineral oil). Synthetic hydrocarbon (SHC) gear oil also increased the efficiency of the best gears by eight to nine percent.
