Benefits and Features

World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.

Simple and efficient turbocharger or series turbocharger for high power applications.

Fuel consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.

Tier 4 Interim or Tier 4 Final, Stage IIIB or Stage IV engines require Ultra Low Sulfur Diesel (ULSD) fuel containing a maximum of 10 ppm sulfur (EU) and 15 ppm sulfur (U.S.), and new oil formulations to support the new technology. Cat® engines are designed to accommodate B20 biofuel. Your Cat dealer can provide more information regarding fuel and oil.

Industry leading range of factory configurable ratings and options for agricultural, material handling, construction, mining, aircraft ground support, and other industrial applications.

  • Scheduled maintenance, including SOS℠ sample
  • Customer Support Agreements (CSA)
  • Caterpillar Extended Service Coverage (ESC)
  • Superior dealer service network
