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.Caterpillar is not in the position to continuously evaluate and monitor all the many worldwide distillate diesel fuel specifications and the on-going revisions that are published by governments and technological societies.The “Caterpillar Specification for Distillate Fuel for Off-Highway 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, etc.) when used in Cat diesel engines.Using the Cat distillate diesel fuel specification as the baseline, it is much easier to 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 be used, 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, and/or 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 (e.g. fuel can be cooled to address low viscosity; etc.).
Some fuel parameters that are outside of specification limits may be able to be improved with the use of appropriate amounts of well proven fuel additives. Refer to this Special Publication, "Distillate Diesel Fuel" article, “Aftermarket Fuel Additives” and “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 “Caterpillar Specification for Distillate Fuel for Nonroad Diesel Engines”, Table 1.Note: The diesel fuel has to be bright and clear. 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, etc.). Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.
