Lubricant Viscosity Recommendations
The proper SAE grade of oil to select is determined by the minimum outside temperature at which the engine will be started and the maximum outside temperature in which the engine will be operating. This recommendation is to ensure the correct viscosity is used until the next oil change. 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 following 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 engines can still be subjected to normal oil temperatures because of regulated temperature components. The higher viscosity oils will provide better protection to all components which it contacts during the full operating cycle.To determine if the oil in the crankcase will flow in cold weather, remove the oil dipstick before starting. If the oil will flow off, the oil is fluid enough to circulate properly.Lubricant Viscosity Chart
Air Starting Motor Oiler
A lubricator should be used with the starting system.* Use 10 weight non-detergent engine oil above 0°C (32°F) or* diesel fuel at temperatures below 0°C (32°F).Governor Oil
* Use SAE 10W30 non-detergent engine oil for all temperatures.Refill Capacities
The sump 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.The Total Cooling System capacity will vary, depending on the radiator size and capacity provided by the OEM manufacturer. In order to properly maintain the cooling system, Total Cooling System capacity must be known. The chart is left blank and should be filled in by the customer to determine the Total Cooling System Capacity for his engine and application.3606 Engine
