Features

Reliable, Quiet and Durable Power

World-class manufacturing capability and processes coupled with proven technologies and extensive field validation assure reliability and durability in tough nonroad applications.

High Performance

Leading edge fuel systems and turbocharging provide high torque even at lower engine speeds.

Fuel Efficiency

Fuel consumption optimized to match the measured operating cycles of a wide range of equipment types.

Fuel & Oil

U.S. EPA Tier 4 Interim or Tier 4 Final, EU Stage IIIB, Stage IV or proposed Stage V 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. Your Cat dealer can provide more information regarding fuel and oil.
