GASKET KIT-FUEL SYSTEM 6V3729 - Caterpillar

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Selection of Oil Change Interval
Refer to this Operation and Maintenance Manual, "Refill Capacities" for further information about oils that may be used in Caterpillar engines.Reduced Oil Change Intervals
In some severe service applications, reducing the oil change interval may be necessary in order to maintain the integrity of the engine lubricant. Refer to this Operation and Maintenance Manual, "Severe Service Operation - Check" or consult with yourCat dealer in order to determine whether your engine is operating under severe service conditions. Some severe service operating conditions are listed below:
Abnormally harsh operating cycles
Harsh environments
Arctic temperatures
Corrosive environments
Extremely dusty conditions
Poor maintenance of air filters or of fuel filtersExtended Oil Change Intervals
Recommended multigrade oil types are listed in Table 1. Do not use single grade oils.Note: The following requirements must be met in order to use Table 1.
S O S Services oil analysis is performed at all oil changes. The S O S Services lab must be notified of the extended oil change interval. The use of an extended oil change interval makes a difference in the interpretation of the data.
Cat Advanced Efficiency oil filter is used.
A Cat Advanced Efficiency 4 micron(c) absolute or less fuel filter is used.

(1) The standard oil change interval in this engine is 250 hours, if the operating conditions and recommended oil types that are listed in this table are met. If the type of oil, the quality of the oil and the operating conditions meet certain standards, the oil change intervals may be increased to 500 hours. Refer to Special Publication, PEHJ0192, "Optimizing Oil Change Intervals" in order to determine whether the oil change interval can be extended beyond 250 hours.
(2) Normal conditions include these factors: Fuel sulfur below 0.3%, altitude below 1830 m (6000 ft) and good air filter and fuel filter maintenance. Normal conditions do not include high load factor, harsh operating cycles, or harsh environments.
(3) High load factors can shorten the service life of your engine oil. Continuous heavy load cycles and very little idle time result in increased fuel consumption and oil contamination. These factors deplete the oil additives more rapidly. If the average fuel consumption of your engine exceed 43 L (11 US gal) per hour, follow the “High Load Factor” recommendations in Table 1. To determine average fuel consumption for your engine, measure average fuel consumption for a period of 50 to 100 hours. If
