Lubricant Viscosity Recommendations
See chart for recommended viscosity and temperature range. The required performance criteria for the oil is defined in the previous Lubricant Specification section.The minimum temperature for the viscosity grade provides guidelines for the lowest starting temperature with a "cold soaked" engine. 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 is to use the highest viscosity oil possible. Even though the ambient temperature may be low, operating engines can still be subjected to normal oil temperatures because of regulated temperature components. Higher viscosity fluids provide better protection to all components contacted during the full day work cycle.Multi-viscosity oils are preferred because of full protection through a wider temperature range. See chart for recommended viscosity and temperature range.To determine if the oil in the crankcase will flow in cold weather, remove the oil dipstick before starting the engine. If the oil flows off, the oil is fluid enough to circulate properly.Lubricant Viscosity Chart
Refill Capacities
These refill capacities reflect the crankcase capacity plus filter. Auxiliary oil filter systems will require additional oil. For all auxiliary oil filter system information consult the OEM or auxiliary oil filter system manufacturer.In order to properly maintain the cooling system, Total Cooling System capacity must be known. This capacity information will be needed to determine the amount of antifreeze and coolant additive (conditioner) required for the cooling system.
