FUEL Model year 2007 and newer Caterpillar on-highway diesel engines require the use of ULSDfuel in order to meet the United States (U.S.)Environmental Protection Agency (EPA) 2007emissions regulations for on-highway dieselengines. Failure to use ULSD in these engines ispunishable with civil penalties.
Ultra Low Sulfur Diesel (ULSD) fuel will have ≤ 15 ppm (0.0015%) sulfur using the ASTM D5453, ASTM D2622, or DIN 51400 test methods.
CRANKCASE LUBE OILDiesel engine oils meeting the Cat ECF-3(Engine Crankcase Fluid-3) specification arestrongly recommended for use in 2007 modelyear and newer Caterpillar on-highway dieselengines. The Cat ECF-3 specification wasdeveloped in order to protect emissions controlsystems, help comply with the emissionsstandards, reduce engine wear, and controlpiston deposits and oil consumption in 2007model year and newer on-highway dieselengines that are designed to use fuels with ≤ 15ppm (0.0015%) sulfur.
The combination of ULSD fuel and API CJ-4compliant diesel engine oil is stronglyrecommended for optimum engine systemperformance.
Note: Oils that meet the API CJ-4 oil categoryrequirements are Cat ECF-3 compliant.
FUEL AND LUBE OIL REQUIREMENTSGEARING CONSIDERATIONSThe C15 On-Highway Diesel Engine offers awide operating range and high torque rise, whichpromotes the use of transmissions with fewergears. Even with this built-in feature,heavy/specialty haulers must remember theirtrucks should be geared to achieve theappropriate compromise between startability anddesired road speed. The general principal driversshould follow is that of the “gear fast, run slow”strategy to achieve optimal performance.
For the best balance of performance and fueleconomy, spec axle ratios and tire sizesaccording to the following:
• 80,000 lb GCW or lessLess than 1750 lb-ft: 1400 rpm @ 65 mph (105 km/h)
1750 lb-ft and above:1325 rpm @ 65 mph (105 km/h)
• 90,000 lb GCW or more1500 – 1650 rpm @ cruise speed
Multi-Torque:• 80,000 lb GCW or less435-hp, 1550/1750 lb-ft:1325 rpm @ 65 mph (105 km/h)
475-hp, 1650/1850 lb-ft:1325 rpm @ 65 mph (105 km/h)
Maximum recommended engine speed at cruiseis 1500 rpm.
The minimum startability requirements are 10%for pick-up and delivery, 14% for linehaul, 20%for on/off highway, and 25% for off-highway. Atpeak torque rpm in top gear, the recommendedgradeability is 1.8% (1.5% minimum). At cruisespeed in top gear, 1.0% is the ideal gradeability.
To optimize your truck’s performancecharacteristics, a computerized spec’ing toolcalled Design Pro is offered by your Caterpillardealer. It calculates effects of various drivelinevariables on engine operation such astransmissions, axles, and tires. This analysisallows you to verify that your truck’s drivelinespecifications are best suited to your application.
