FS Suprex Gold ESP SAE 15W-40

FS Suprex Gold ESP (Exhaust System Protection) SAE 15W-40 is an API CK-4/SN premium heavy-duty engine oil formulated with advanced technology to provide superior engine life for on- and off-highway applications as well as the added protection needed for the exhaust after-treatment devices, such as the diesel particulate filters (DPFs) and the diesel oxidation catalysts (DOCs). FS Suprex Gold ESP SAE 15W-40 is backwards compatible with all API oil service categories and engine models that operate on diesel fuels with sulfur content up to 500 ppm.


Features and Benefits: 

  • Industry-leading shear stability maintains viscosity in support of extended drain intervals
  • Enhanced aeration control protects against air, foam and bubbles to help maintain the integrity of the oil for proper film protection
  • Excellent oxidation protection at higher temperatures
  • Specially formulated to meet the requirements of exhaust gas recirculation (EGR)-, DPF-, and DOC-equipped engines as well as enhance the performance and durability of older engines
  • Protects against high-temperature oxidation and viscosity breakdown under severe conditions of extreme temperatures or heavy engine loads
  • Provides exceptional oil consumption control, which will lower oil costs as a result of less make-up oil during operation
  • Formulated to provide superior soot control for protection against abrasive wear and sootinduced oil thickening
  • Blended with hydrocracked group II and group II plus base oils, refined using the most advanced techniques available
