Lubricant Viscosities
These machine oil compartment recommendations refer only to the SAE viscosity grade for the expected ambient temperature range.The required performance criteria for the oils are defined in the previous lubrication specification section.The minimum temperature for the viscosity grade provides guidelines for the lowest starting temperature with a "cold soaked" machine. Base stocks for blending the oil formulations do differ and variations can exist within a viscosity grade on low temperature characteristics. Therefore, a particular oil may allow lower starting temperatures than given in the chart. Your oil supplier can provide additional information on oil properties.The recommendation would be to use the highest viscosity oil possible. Even though the ambient temperature may be low, operating machines can still be subjected to normal oil temperatures because of regulated temperature components. The higher viscosity fluids will provide better protection to all components which it contacts during the full day work cycle. When operating below -20°C (-4°F), Cold Weather Recommendations (SEBU5898), available from your Caterpillar dealer, will provide more information for the extreme conditions.Refill Capacities
