Fuel Specifications and Information
Types of Fuel
Caterpillar diesel engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups, preferred and permissible.The preferred fuels provide maximum engine service life and performance. They are distillate fuels. They are commonly called diesel fuel, furnace oil, gas oil or kerosene.The permissible fuels are crude oils or blended fuels. Use of these fuels can result in higher maintenance costs and reduced engine service life.Refer to "Fuels for Caterpillar Diesel Engines," Form SEHS7067, for a detailed summary of preferred and permissible fuels and their specifications.Refer to S.A.E. J313 Diesel Fuels for information about better quality fuels, such as ignition quality, gravity/density, viscosity, cloud point, sulfur content, etc.Fuel Sulfur Content
The percentage of sulfur in the fuel will affect the engine oil recommendations (see "Engine Oils" under "Lubricant Specifications).Fuel sulfur is chemically changed during combustion to form sulfuric acid. The acid chemically attacks metal surfaces and causes corrosive wear. Higher engine oil TBN (total base number) values are essential to minimize corrosive wear.Periodically request fuel sulfur content information from your fuel supplier. Fuel sulfur content can change with each bulk delivery.Fuel Cetane Requirement
The minimum fuel cetane number recommended for the direct injection engine is 40.Fuel Cloud Point
Fuel waxing can plug the fuel filters in cold weather. The fuel cloud point must be below the temperature of the surrounding air to prevent filter waxing and power loss. Fuel heating attachments are available from your Caterpillar dealer to minimize fuel filter waxing.Lubricant Specifications
Certain abbreviations listed below follow S.A.E. J754 nomenclature. Some classifications follow S.A.E. J183 abbreviations. The MIL specifications are U.S.A. Military Specifications. The definitions other than Caterpillar's will be of assistance in purchasing lubricants. The recommended oil viscosities can be found in the "Lubricant Viscosities" chart in this publication. The prefix "SPC" is a general abbreviation used by Caterpillar to identify special oils such as synthetic or semi-synthetic oils.Diesel Engine Oils (DEO)
Caterpillar has two engine oils. To achieve the maximum engine life and performance in your diesel engines, Caterpillar's first recommendation is: * CAT Diesel Engine Oil (DEO)CAT Diesel Engine Oil is specially formulated for Caterpillar diesel engines to reduce piston and ring deposits and thus provide longer engine life and stable oil control.Engine Oil (EO)
CAT Engine Oil is Caterpillar's second recommendation for an engine oil specifically intended for use in mixed fleets. This oil is only for the convenience of having the same oil for gasoline and diesel engines.For mixed fleet convenience, use Caterpillar's: * CAT Engine Oil (EO)If circumstances require the use of an oil other than the CAT Diesel Engine Oil or CAT Engine Oil, the following oil specifications can be used: European Oil Specification CCMC D3, API Specification CD, CD/SF, CE, or Military Specifications MIL-L-2104C or MIL-L-2104D.Oil with these specifications may require shortened oil change periods as determined by close monitoring of oil condition with Scheduled Oil Sampling (S O S) and infrared analysis. The percentage of sulfur in the fuel will affect the engine
