Fuel System Information
Fill the fuel tank at the end of each day of operation to drive out moist air and to prevent condensation. Do not fill the tank to the top. Fuel expands as it gets warm and may overflow.
Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to fuel system parts.
Fuel Recommendations
Preferred Fuel Grades
The two types of preferred diesel fuel available for your truck engine are typically grades No.1 (winter) and No.2 (summer). Although No.2 diesel fuel is the most commonly used fuel, No.1 diesel fuel or a blend of No.1 and No.2, is the fuel that is best suited for cold weather operation.There are three major differences between No.1 and No.2 diesel fuel.* No.1 diesel fuel has a lower cloud point. The cloud point is the temperature at which a cloud or haze of wax crystals will begin to form in the fuel and cause fuel filters to plug.* No.1 diesel fuel has a lower pour point. The pour point is the temperature which diesel fuel will begin to thicken and be more resistant to flow through fuel pumps and lines.* No.1 diesel fuel has has a lower kJ (Btu) (heat content) rating per unit volume of fuel than the average No.2 diesel fuel. When using No.1 diesel fuel or modified summer blended fuel, you may notice a drop in power and fuel efficiency, but should not experience any other operating effects.Before troubleshooting for low power or poor performance in winter months, check the type of fuel or fuel blend being used. Be aware of these fuel values when purchasing your diesel fuel and anticipate the average outside (ambient) temperature for the area your engine will be operating. Engines fueled in one climate may not operate satisfactorily if moved to another because of problems that result from cold weather. Use only fuel as recommended in this section. The fuels recommended for use in Caterpillar engines are No.2-D diesel fuel and No.2 fuel oil (summer), although No.1 (winter) grades are acceptable. The following fuel specifications are worldwide fuels which also meet Caterpillar requirements. These fuel characteristics should be considered when procuring fuel for use in Caterpillar diesel truck engines. Caterpillar Diesel Engines are capable of burning a wide range of distillate fuels. The use of clean, stable blends of distillate fuel which meet the following requirements will provide quality engine service life. Permissible Alternate Fuels
Fuel Mixing for Arctic Operation
Refer to the Cold Weather Operation topic in this Manual or the Truck Owner Manual for additional information.During cold weather operation, it may be necessary for you to use No.2 diesel fuel since quantities of No.1 diesel fuel are limited and generally are only available during the winter months and in the colder climates. In this case, summer grade fuel may be blended with No.1 fuel or kerosene in the following proportions. In temperatures down to -54°C (-65°F), use of distillate fuels meeting the following specifications are permitted. These fuels are lighter
