Cat Diesel Engine Oils
Cat fluids have been developed and tested by Cat in order to provide the full performance and service life that has been designed and built into Cat engines. The quality of finished oil is dependent on the quality of the base stock, the quality of the additives, and the compatibility of the base stock and additives. Cat fluids are formulated of high quality refined oil base stocks and additives of optimal chemistry and quantity in order to provide high performance in engines and machine components. Cat fluids are used for factory fill of Cat engines and components and are offered by Cat dealers for service fills and as aftermarket products. Consult your Cat dealer for more information on these Cat fluids.Due to significant variations in the quality and in the performance of commercially available oils, Cat recommends the oils that are listed in Table 1 for 3600 and C280 Series engines that use distillate diesel fuel.
