• Cat C9.3B engines meeting Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA, are compatible with diesel fuel blended with the following lower-carbon intensity fuels* up to: 20% biodiesel FAME (fatty acid methyl ester) or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. 
    
• Engine Idle Speed Management helps maximize fuel efficiency and reduce greenhouse gas emissions by elevating engine speed to an intermediate idle to complete specific tasks and returning to low idle when finished. 
    
• Automatic Load Control helps you save fuel and reduces greenhouse gas emissions by automatically matching milling speed to engine load for maximum production at peak efficiency.
    
• Standby/Resume pauses major machine functions and lowers engine speed to conserve fuel and helps reduce greenhouse gas emissions during truck exchanges.
    
• Traction Control maintains consistent traction to increase machine efficiency, helps reduce fuel burn and greenhouse gas emissions.
    
• Cat Scheduled Oil Sampling (S•O•S^SM) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine’s operation and maintenance manual for more information.
    
• Cat Grade with Grade and Slope for cold planers allows for accurate material planning to help reduce overages during the paving process and increase final project quality for a longer lasting road surface.
    
• Don’t waste fuel idling. Cat VisionLink online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
    
• VisionLink displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
