	Note (1)	Rated net power is the power the engine delivers at the flywheel when equipped with fan, air intake, exhaust systems and alternator, at 2000 rpm. Rated power is tested to the applicable standard in effect at time of manufacture.
	Note (2)	‘Cat diesel engines require ULS Diesel (Ultra-Low Sulfur Diesel, max 15 ppm sulfur) or blends of ULS Diesel with lower sulfur diesel**; up to 20% biodiesel FAME (Fatty Acid Methyl Ester) or 100% renewable diesel HVO (Hydrotreated Vegetable Oil) and GTL (Gas-to-liquid) fuels. For successful application, refer to your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250). *While Caterpillar engines are compatible with these alternative fuels, some regions may not permit their use. **Low sulfur diesel has similar greenhouse gas emissions to conventional diesel. ***Engines without aftertreatment can use up to 100% biodiesel blends (for blends >20%, consult your Cat dealer).
