Note (1) Net power advertised is the power available at the flywheel at 2000 rpm when the engine is equipped with fan, intake system, exhaust system and alternator. The power advertised is tested to the specified standard in effect at the time of manufacture.
Note (2) ¹Cat diesel engines require ULSD (Ultra-Low Sulfur Diesel, 15 ppm or less) or blends of ULSD with the following lower carbon intensity fuels**: up to 20% biodiesel FAME (Fatty Acid Methyl Ester)* or up to 100% renewable diesel, HVO (Hydrotreated Vegetable Oil) and GTL (Gas-to-liquid) fuels. Refer to guidelines for successful application. Consult your Cat dealer or Caterpillar Machine Oil Recommendations (SEBU6250) for details. *Engine without aftertreatment equipment can use up to 100% biodiesel blends (for blends above 20% biodiesel, consult your Cat dealer). **Tailpipe greenhouse gas emissions of lower carbon intensity fuels are similar to conventional fuels.
