Caterpillar is not in the position to continuously evaluate and monitor all of the many worldwide distillate diesel fuel specifications and their ongoing revisions that are published by governments and technological societies.The "Caterpillar Specification for Distillate Fuel for On-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 Caterpillar diesel engines.Using the Caterpillar 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 Caterpillar distillate diesel fuel specification.
Use the Caterpillar distillate diesel fuel specification as a fuel quality baseline for comparison of distillate diesel fuel analysis results to, and/or a baseline for comparison of other distillate diesel fuel specifications to.
Typical fuel characteristics can be obtained from the fuel supplier.Fuel parameters outside of the Caterpillar fuel specification limits have explainable consequences.
Compensate for some fuel parameters that are outside of the specification limits (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 (Fuel Recommendations for On-Highway Diesel Engines)" 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 "Caterpillar Specification for Distillate Fuel for On-Highway 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, etc.). Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.
Model year 2007 and newer (U.S. EPA 2007 certified) on-highway diesel engines REQUIRE the use of Ultra Low Sulfur Diesel (ULSD) fuel (≤ 15 ppm sulfur)."Sulfur-free" diesel fuel (≤ 10 ppm sulfur) is strongly recommended for use in "EURO IV" certified on-highway diesel engines, while diesel fuel with ≤ 50 ppm sulfur is acceptable.Low Sulfur Diesel (LSD) fuel (≤ 500 ppm sulfur) is strongly recommended (required in the U.S.) for use in model year 2006 and older on-highway diesel engines, while diesel fuel with ≤ 5000 ppm sulfur is acceptable for use in areas of the world where allowed by law. Diesel Oxidation Catalyst (DOC) equipped engines require the use of LSD fuel or ULSD fuel.
Note: In the U.S., burning fuel with greater than 15 ppm sulfur in model year 2007 and newer on-highway diesel engines is illegal and punishable with civil penalties.Engines that are manufactured by Caterpillar are certified by use of the prescribed U.S. Environmental Protection Agency (EPA) and European Certifications fuels. Caterpillar does not certify diesel engines on any other fuel.Note: The owner and the operator of the engine has the responsibility of using the correct fuel that is recommended by the manufacturer and allowed by the U.S. EPA and, as appropriate, other regulatory agencies.
Ultra Low Sulfur Diesel (ULSD) fuel will have ≤15 ppm (0.0015%) sulfur using the "ASTM D5453", "ASTM D2622", or "ISO 20846, ISO 20884" test methods. Model year 2007 and newer Caterpillar on-highway diesel engines REQUIRE the use of ULSD fuel in order to meet the U.S. EPA 2007 emissions regulations for on-highway diesel engines. In the U.S., failure to use ULSD in these engines is illegal and punishable with civil penalties. Model year 2007 and newer Caterpillar on-highway diesel engines are designed to operate on ULSD. Failure to use ULSD in these engines will reduce engine efficiency and durability. Failure to use ULSD may also damage emission control systems and reduce fuel economy. Refer to the Frequently Asked Questions article in the "Reference Information" section of this Special Publication for additional ULSD fuel information. In addition, certain other governments/localities MAY require the use of ULSD fuel. Diesel engines equipped with a Diesel Particulate Filter (DPF) require the use of ULSD. Other emission controlled diesel engines and/or diesel engines equipped with exhaust aftertreatment devices MAY also require the use of ULSD fuel. Consult federal, state, and local authorities for guidance on fuel requirements for your area. Also, consult the specific engine Operation and Maintenance Manual for guidance.When ULSD is used, there are concerns with fuel viscosity, lubricity, and thermal stability. The fuel viscosity, lubricity, and thermal stability limits stated in this Special Publication, "Caterpillar Specification for Distillate Diesel Fuel for On-highway Diesel Engines" address these concerns. In North America, diesel fuels that meet the latest version of "ASTM D975 Grade No. 1-D S15" or "ASTM D975 Grade No. 2-D S15" and meet the "ASTM D975 Thermal Stability Guideline", generally meet the Caterpillar requirements for ULSD fuel.In Europe, diesel fuels that meet the latest version of "European Standard EN590" requirements for ≤ 10 ppm sulfur fuel (typically referred to as "sulfur-free") generally meet Caterpillar requirements for ULSD fuel."Sulfur-free" diesel fuels (≤ 10 ppm sulfur) as defined in the latest version of "European Standard EN590" are strongly recommended for use in "EURO IV" certified on-highway diesel engines, while diesel fuel with ≤ 50 ppm sulfur is acceptable. Use of diesel fuel with greater than 50 ppm in Caterpillar "EURO IV" engines will reduce the engine efficiency and durability, and may reduce fuel
