D-A RREO 7™ SAE 20W-40 is designed to meet the stringent performance requirements of new / remanufactured Tier 4 locomotives utilizing ULSD (ultra-low sulfur diesel) and operating under more severe conditions with less oil consumption and lower emissions. It offers reduced SAPS (sulfated ash, phosphorous and sulfur), advanced detergency and dispersancy technology and increased yellow metal and anti-wear protection critical to satisfactory operation and long component life of exhaust after treatment devices (particulate filters and oxidation catalysts). In addition, it affords enhanced alkalinity (TBN) retention and oil consumption reduction characteristics.
