¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) and are compatible* with ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)*** 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. *While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use. ** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. *** Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).

Air Conditioning System
Air Conditioning
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. If equipped with R134a (Global Warming Potential = 1859), the system contains 1.3 kg (2.9 lb) of refrigerant, which has a CO2 equivalent of 1.859 metric tonnes (2.049 tons). If equipped with R1234yf (Global Warming Potential = 0.501), the system contains 1.1 kg (2.4 lb) of refrigerant which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons).
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. – If equipped with R134a (Global Warming Potential = 1430), the system contains 0.90 kg (1.984 lb) of refrigerant, which has a CO2 equivalent of 1.287 metric tonnes (1.419 tons). – If equipped with R1234yf (Global Warming Potential = 0.501), the system contains 0.780 kg (1.719 lb) of refrigerant, which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons).
