Lubrication System
Significant variations in the quality and in the performance of commercially available oils exists. Cat recommends the oils that are listed in Table 1 for C280 Engines that use distillate diesel fuel.

To help ensure optimum engine performance, a complete fuel analysis should be obtained before engine operation. The fuel analysis should include all of the properties that are listed in the “Cat Specification for Distillate Fuel for Nonroad Diesel Engines”, Table 3.The values of the fuel viscosity given in table 3 are the values as the fuel is delivered to the fuel injection pumps. For ease of comparison, fuels should also meet the minimum and maximum viscosity requirements at 40° C (104° F) that are stated by the use of either the "ASTM D445" test method or the "ISO 3104" test method. If a fuel with a low viscosity is used, cooling of the fuel may be required to maintain 1.4 cSt or greater viscosity at the fuel injection pump. Fuels with a high viscosity might require fuel heaters to lower the viscosity to either 4.5 cSt or less for rotary fuel injection pumps or 20 cSt viscosity or less for all other fuel injection pumps.Table 3 is for diesel fuels that are distilled from conventional sources (crude oil, shale oil, oil sands). Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.
