Fuel Information
Use only fuel as recommended in this section.
Fill the fuel tank at the end of each day of operation to drive out moist air and to prevent condensation. Maintain a fairly constant level in the day tank (near the top) to avoid drawing moisture into the tank as the level decreases. Do not fill the tank to the top. Fuel expands as it gets warm and may overflow.Do not fill the fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to the fuel system parts.
Drain the water and sediment from any fuel storage tank before it is refilled. This will help prevent water and/or sediment from being pumped from the fuel storage tank into the engine fuel tank.Fuel Tanks
Fuel tanks should contain some provision for draining water and sediment from the bottom of the tanks. A primary fuel filter and/or water separator is recommended and should be installed between the fuel tank and the engine fuel inlet.Some fuel tanks use supply pipes that allow water and sediment to settle below the end of the fuel supply pipe. This water and sediment should be drained at each oil change. Do not use fuel tanks with supply lines that take fuel directly from the bottom of the tank. Fuel supply connections to the engine must be at least 75 mm (3 in.) above bottom of fuel tank.If there is a fuel return line from the engine, it should return excess, hot fuel to the tank from which it was taken. Do not return fuel to the day tank (if equipped), as fuel overheating could cause a decline in engine performance.The fuel return line should deposit fuel at the top of the tank opposite the supply connection. This allows the engine to get warm fuel from the tank. It also allows air to escape from the return fuel without being pulled back into the engine. If hot fuel must return to the day tank, a fuel cooler is required.Fuel Heaters
Use of a fuel heater can help eliminate some cold weather problems. A fuel heater should be installed so that the fuel is heated before it goes into the first or primary fuel filter. Select a fuel heater that is mechanically simple, yet adequate for the application. The fuel heater should also prevent overheating of the fuel. Disconnect or deactivate the fuel heater in warm weather. Use only thermostatically controlled or self-regulating fuel heaters as recommended. Do not use fuel heaters in warm temperatures.For further information on fuel heaters, contact your GMC TopKick/Chevrolet Kodiak dealer, who is an authorized Cat 3116 engine dealer.Fuel Types
Caterpillar Diesel Engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups, preferred and permissible.The preferred fuels provide maximum engine service life and performance. They are distillate fuels. They are commonly called diesel fuel, MDO diesel, furnace oil, gas oil or kerosene (for cold weather operation).Experience has proven that distillate fuels meeting the following basic
