Information:

Distillate Diesel Fuel
Diesel fuels that meet the specifications in the chart below will provide rated engine performance and full component service life. In North America, diesel fuel identified as No. 1-D and No.2-D in ASTM D975 generally meet these specifications. This chart is for diesel fuels that are distilled from crude oil. Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.. There are many other diesel fuel specifications published by governments and technical societies. Those diesel fuel specifications usually do not contain all of the parameters addressed by Caterpillar in this specification. To assure optimum engine performance, a complete fuel analysis should be obtained prior to engine operation. The fuel analysis should include all of the properties listed in the Distillate Fuel Recommendations chart. If a particular fuel does not meet the minimum Caterpillar requirements, the engine could exhibit excessive fuel system wear, fuel system failure, or excessive engine wear caused by deposits or corrosion.0.05 Percent Sulfur Diesel Fuel
In the U.S.A., 0.05 percent sulfur diesel fuel has been used in all on-highway diesel truck engines since January 1, 1994. This low sulfur fuel was mandated as a means of directly reducing particulate emissions from diesel truck engines. This low sulfur fuel will also be used in Caterpillar commercial diesel engines where low emissions are required and where supply sources provide this type of fuel. Caterpillar has not seen any detrimental effects with 0.05 percent sulfur fuel in Caterpillar commercial diesel engines.
Heavy Fuel Oil (HFO), Residual fuel, or Blended fuel must NOT be used in Caterpillar diesel engines (except in certain 3600 Series HFO engines). Severe component wear and component failures will result if HFO type fuels are used.
