Operating with fuels that do not meet Caterpillar's recommendations can cause the following effects: starting difficulty, poor combustion, deposits in the fuel injectors, reduced service life of the fuel system, deposits in the combustion chamber and reduced service life of the engine.
Cold-soaked starts occur when the engine has not been operated for a time, allowing the crankcase oil and the fuel to become more viscous due to cooler ambient temperatures. Consult the factory if the viscosity of the cold-soaked fuel in the fuel system will be above 20 cSt.
If a particular crude oil exceeds the limits that are listed in Table 1, 3600 Series diesel engines that are configured to use heavy fuel oil may be utilized. Consult your Cat dealer or Customer Service for information about fuel that exceeds the limits that are listed in Table 1.Note: The Crude Oil Specification for Cat 3600 and C280 Series Diesel Engines is applicable to 3500 Series Diesel Engines. Consult your Cat dealer for guidance.
Use of permissible fuels, such as some crude oils, some blends of crude oil with distillate fuel, some biodiesel, and some marine diesel fuel, can result in higher maintenance costs and reduced engine life.
