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 EL250 ( Natural Gas Engine Oil)
Cat NGEO EL350 ( Natural Gas Engine Oil)SAE 40 is the ONLY type of oil that is recommended for Caterpillar G3600 Gas Engines. Multigrade oils are NOT recommended for use in Caterpillar G3600 Gas Engines.

(1) SAE 40 is the ONLY type of oil that is recommended for 3600 Gas engines. Multigrade oils are NOT recommended for use in Caterpillar Gas Engines.For further information about oils, see Special Publication, SEBU6400, "Caterpillar Gas Engine Lubricant, Fuel, and Coolant Recommendations".Lubricant Capacities

Hydraulic Oil
Cat 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 use in Caterpillar hydraulic systems.Caterpillar also has a biodegradable hydraulic oil that is available for use in hydraulic systems. This fluid is recommended for the hydraulic systems when environmental compliance is required or desired.For further information on choosing a hydraulic oil, see Special Publication, SEBU6400, "Caterpillar Gas Engine Lubricant, Fuel, and Coolant Recommendations".Capacity of the Electrohydraulic Actuator's System

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 (combinations of hydrogen and carbon) 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:
Evaluate the fuel with the Caterpillar Methane Number Program, LEKQ6378. 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
