  • Reported savings of up to 5% better fuel economy improvement compared to SAE 15W-40
  • Exceeds API service levels CJ-4, CI-4, CH-4, CG-4, CF-4 and current OEM warranty requirements for extended service
  • Meets, or exceeds, pre and post-2007 emissions requirements
  • Safe for use in applications equipped with Exhaust Gas Recirculation (EGR) and diesel particulate filters (DPF) systems
  • Advanced viscosity and soot control technology for shear stability and engine cleanliness
