Not following the recommendations found in this Special Publication can lead to reduced performance and compartment failure.
Cat Fluids
Cat fluids have been developed and tested by Caterpillar in order to increase the performance of Cat components and the life of Cat components. 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 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 Caterpillar dealers for service fills and as aftermarket products. Consult your Caterpillar dealer for more information on these Cat fluids.
