Lubricant Recommendations
Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations:
Cat NGEO (Natural Gas Engine Oil)
Cat NGEO EL350The proper SAE viscosity grade of oil is determined by the minimum ambient temperature during cold engine start-up, and the maximum ambient temperature during engine operation. To determine the oil viscosity that is required for starting a cold soaked engine, refer to the minimum temperature in Table 1. To select the oil viscosity for operation at the highest anticipated ambient temperature, refer to the maximum temperature in the Table. Use the highest oil viscosity that is available in order to meet the required temperature during start-up.
Table 1
Engine Oil Viscosity
Cat NGEO
Grade of Viscosity Ambient Temperature
Minimum Maximum
SAE 30(1) 0 °C (32 °F) 40 °C (104 °F)
SAE 40(1) 5 °C (41 °F) 50 °C (122 °F)
(1) Cat NGEO is available in these grades only. Multigrade oils are NOT recommended for use in Caterpillar Gas Engines. If other grades of viscosity are selected, ensure that the oil meets the requirements for Caterpillar Gas Engines.For further information about oils, see Special Publication, SEBU6400, "Caterpillar Gas Engine Lubricant, Fuel, and Coolant Recommendations".Lubricant Capacities
The capacity of the engine crankcase includes the capacity of the oil filters that are installed at the factory.

G3520B 541 141 Hydraulic Oil
Caterpillar HYDO (Hydraulic Oil) is recommended in most hydraulic systems. If Caterpillar oils cannot be used, the following commercial classifications can be used in hydraulic systems:
CH-4 engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
CG-4 engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
CF-4 engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)
CF engine oils that have a minimum zinc additive of 0.09 percent (900 ppm)Note: Industrial hydraulic oils are not recommended for service fill in Caterpillar hydraulic systems.For further information on choosing a hydraulic oil, see Special Publication, SEBU6400, "Caterpillar Gas Engine Lubricant, Fuel and Coolant Recommendations".Biodegradable Hydraulic Oil
Caterpillar HEES (Biodegradable Hydraulic Oil) is available for use in hydraulic systems. This fluid is recommended for the hydraulic systems when environmental compliance is required or desired. This fluid is formulated with the following components: a saturated HEES (Hydraulic Environmental Ester Synthetic), synthetic base stock and selected additives.Note: Use this oil only in hydraulic systems.If Caterpillar HEES is not used, commercial oils that meet the Caterpillar BF-1 specifications may be used.
Do not use Caterpillar HEES or commercial oils that meet the BF-1 specification in compartments containing friction material. Refer to the Operation and Maintenance Manual or contact your local Caterpillar dealer for guidance before using Caterpillar Biodegradable Hydraulic Oil (HEES) or commercial oils that meet the BF-1 specification.

Fuel Recommendations
Caterpillar gas engines will operate successfully on a broad range of gaseous fuels. Pipeline natural gas has been used for many years. Commercial fuel gases are mixtures of gases. These fuels consist primarily of hydrocarbons and some inert gases. The compositions of these gas mixtures have extreme variations. Fuels such as wellhead gas, bio-gas, and manufactured gas need to be reviewed for acceptability. Analyze the fuel in order to determine the following characteristics:
Composition
Contaminants
Heat value
Methane number
Specific gravityField gas can have varying characteristics of combustion. Field gas can contain numerous harmful impurities. The impurities can alter the BTU content. The impurities can also alter the methane number. The impurities include everything from water up to complex hydrocarbons that can lead to detonation and severe engine damage. To minimize these effects, Caterpillar recommends the following guidelines:
Use Caterpillar Methane Program 6.01, LEKQ6378 in order to evaluate the fuel. Methane values below 30 are not recommended for use in a Caterpillar engine. Fuels with a methane number that is below 30 must first be processed in order to remove harmful impurities in the fuel and raising the methane number into the acceptable range.
If necessary, use an engine that is configured for a fuel that has a high energy. Consult the appropriate manual for the engine in order to determine the recommended engine timing.
Reduce the oil change interval according to the results of the oil analysis. For further information on fuels, see Special Publication, SEBU6400, "Caterpillar Gas Engine Lubricant, Fuel, and Coolant Recommendations".Cooling System
Coolant Recommendations
During shipping and storage, the engine must be protected from damage that can be caused by freezing of the cooling system. If the engine is shipped to a site with freezing temperatures and/or if the engine is stored in a location with freezing temperatures, the cooling system must contain antifreeze that will withstand the lowest ambient temperature. Frequently check the concentration of glycol in the coolant/antifreeze. Make sure that the concentration is adequate in order to prevent freezing. Otherwise, the cooling system must be completely drained.Coolant/antifreeze is normally composed of three elements: water, glycol and additives. Each element must meet specific guidelines.Water
