The 988 GC emits up to 5% less CO2/hr than the 988K.
Cat U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD 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
Cat 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: 100% 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 Management System and Auto Engine Idle Shutdown reduces idle RPM and maximize fuel efficiency.
Load sensing hydraulics produce flow and pressure on-demand and only in amounts necessary to perform the needed functions.
Cat Payload technology maximizes loading efficiency, helping operators of every skill level work more accurately to reduce load time, fuel costs and greenhouse gas emissions.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
Optional Cat clean emissions module includes Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC), and Selective Catalytic Reduction (SCR) technologies to reduce the engine’s emissions.

*All comparisons to 988K. Productivity, fuel and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link™️ data where available. Productivity improvements are based on test data. 988 GC Large Wheel Loader
