Abstract: Diesel engine oils have been refined to be DL-1 class oils or DH-2 class oils lower in sulfated ash, phosphorous and sulfur named as Low-SAPS oils to protect the diesel particulate filter and the deNOx catalyst. The effect of lowering oil viscosity from SAE10W30 to SAE5W30 on the reduction of frictional power loss in a fired and braked engine was examined by measuring the total friction torque directly by the simplified run-out method. The following study results were made obvious. (1) The total friction losses of the SAE5W-30 oils lowered in viscosity are smaller than those of the SAE10W-30 oils. (2) The effect of DH-2 class oil on reducing the friction loss is larger than that of DH-1 class oil.
