Abstract
This disclosure relates to lubricants with certain amounts of calcium and zinc that tend to perform well in the low-speed FZG scuffing tests of CEC L-07 (FZG A/8.3/90) and further include certain amounts of low molecular weight diol and/or triol compounds to achieve good gear wear performance in FZG wear tests. The lubricants herein are suitable for use as industrial gear oils for transmission fluids (i.e., manual, automatic, or dual-clutch transmissions), gear fluids, axle fluids, differential fluids, and/or lubricating fluids for other gear-type applications configured for heavy-duty applications.
