No. 2D diesel fuel is recommended for use in the 1100 Series Caterpillar Diesel Truck Engines, although No. 1D may be used if desired.In selecting a fuel, note that distillate fuels are especially desirable because the fuel is heated to a vaporous state and condensed, thus eliminating all sediment and residue.There is considerable variation in the composition of fuels distributed under the No. 2D grade classifications. For desirable engine service it is most important to give special attention to cetane no., water and sediment, pour point, cloud point and sulphur content. USE FUELS WHICH MEET THE FOLLOWING REQUIREMENTS:Cetane No. ... 40 minimumWater and Sediment ... 0.1% maximumPour Point ... 10F° (-12C°) below ambient temperatureCloud Point ... No higher than ambient temperatureSulphur Content ... Above 0.4% adjust oil change periodGravity ... 32-40 A.P.I. at 60°F (16°C) Cetane No.: This is an indication of a fuel's ignition quality and should not be less than 40 for this engine. For high altitude operation or cold weather starting, a higher cetane number is required. Water and Sediment: A good clean fuel will contain no more than .1% sediment and water. Dirty fuels lead to early filter plugging and in addition can result in the formation or gums and resins reducing filter and engine life. Pour Point: The pour point of the fuel has no effect on engine performance, as long as the fuel is fluid enough to flow from the fuel tank to the engine. The pour point of the fuel should be at least 10F° (-12°C) below the lowest atmospheric temperature at which the engine must start and operate. In extremely cold temperatures it may be necessary to use No. 1D diesel fuel. Cloud Point: Cloud point is the temperature at which wax crystals become visible and is generally above the pour point of the fuel. The cloud point should be no higher than the lowest atmospheric temperature at which the engine must start to keep the fuel filter elements from plugging with wax crystals. Sulphur Content: As sulphur content increases, the crankcase oil change periods should be reduced. Fuel containing 0.4% or less sulphur content, use normal oil change periods. If the fuel contains 0.4% to 1.0% sulphur, oil change periods should be reduced to one-half normal interval. If the fuel contains more than 1.0% sulphur, oil change periods should be reduced to one-fourth normal interval. Gravity: Gravity is the measurement of heat units in a certain amount of fuel. The heavier the fuel (the lower the number) the more heat units per volume. If a fuel with a higher A.P.I. gravity is used the power produced will be lower. Select fuels with the lower A.P.I. gravity reading.Authorized dealers are familiar with fuels that have given good results in Caterpillar Diesel Engines and should be consulted regarding the fuel to use.
