Note: For on-highway diesel engine fluids requirements, refer to specific engine Operation and Maintenance Manuals, and also refer to the most current revision level of Special Publication, SEBU6385, "Caterpillar On-Highway Diesel Engine Fluids Recommendations". Also consult your Cat dealer.Cat is not in the position to evaluate continuously and monitor all of the many worldwide distillate diesel fuel specifications and on-going revisions that are published by governments and technological societies.The "Cat Specification for Distillate Fuel for Nonroad Diesel Engines" provides a known, reliable baseline to judge the expected performance of distillate diesel fuels that are derived from conventional sources (crude oil, shale oil, oil sands) when used in Cat diesel engines.Use the Cat distillate diesel fuel specification as the baseline. Determine any potential economic and/or performance trade-offs and overall acceptability when using fuels of varying characteristics and quality levels.
When required, have the diesel fuel that either is being used or is planned to use, tested per the Cat distillate diesel fuel specification.
Use the Cat distillate diesel fuel specification as a fuel quality baseline for comparison of distillate diesel fuel analysis results. Also, use the specification as a baseline for comparison of other distillate diesel fuel specifications.
Typical fuel characteristics can be obtained from the fuel supplier.Fuel parameters outside of the Cat fuel specification limits have explainable consequences.
Some fuel parameters that are outside of the specification limits can be compensated for (for example, fuel can be cooled to address low viscosity).
Some fuel parameters that are outside of specification limits may improve with the use of appropriate amounts of proven fuel additives. Refer to this Special Publication, "Distillate Diesel Fuel" article, "Aftermarket Fuel Additives" and "Cat Diesel Fuel Conditioner" topics for guidance.To help ensure optimum engine performance, a complete fuel analysis should be obtained before engine operation. The fuel analysis should include all of the properties that are listed in the "Cat Specification for Distillate Fuel for Nonroad Diesel Engines", Table 1.Note: The diesel fuel cannot have any visually apparent sediment, suspended matter, or undissolved water.Diesel Fuels that meet the specifications in table 1 will help provide maximum engine service life and performance.In North America, diesel fuels that are identified as meeting the latest version of "ASTM D975" Grades No. 1-D or No. 2-D (all listed sulfur levels) generally meet the table 1 requirements.In Europe, diesel fuels that are identified as meeting the latest version of "European Standard EN590" generally meet the table 1 requirements.Table 1 is for diesel fuels that are distilled from conventional sources (crude oil, shale oil, oil sands). Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.
Ultra Low Sulfur Diesel (ULSD) fuel 0.0015 percent (≤15 ppm (mg/kg)) sulfur is required by regulation for use in engines certified to nonroad Tier 4 standards (U.S. EPA Tier 4 certified) and that are equipped with exhaust aftertreatment systems.European ULSD 0.0010 percent (≤10ppm (mg/kg)) sulfur fuel is required by regulation for use in engines certified to European nonroad Stage IIIB and newer standards
