INDICATOR-PRESSURE 1W4304 - Caterpillar

This article contains engine crankcase fluid recommendations for all Cat 3600 Series, C280 Series engines including marine engines, smaller Direct Injection (DI) engines, and Precombustion Chamber (PC) engines. Engine oil requirements of these engines are different than smaller engines due to the specific loads, cycles, and engine speed of these engine models.Engine lubricants play multiple roles in engines. Appropriate lubricants offer the following:
Provide lubrication to the moving components of the engine under a wide range of temperatures
Keep the engine components clean and remove wear debris
Remove heat from the lubricated components
Neutralize acidic products due to combustion process
Protect the engine from cavitation and foaming
Protect the engine from corrosion and rust
Control Oil Consumption
Disperse/Solubilize Contaminants (Soot)
Support the regulated engine emissions limitsCurrent lubricant formulations are more advanced and complex than previous formulations. Current lubricants are developed to support advanced engine technologies that have lower emissions while supporting the performance and durability of these engines.High performance oils are produced and validated using industry standard tests, proprietary tests, field tests, and often prior experience with similar formulation. Cat high quality and high performance lubricants are validated based on these factors.In order to provide optimal engine performance and life and comply with regulated emission reduction, use the recommended engine oil as provided in this special publication. Due to the significant variations in the quality and performance of commercially available oils, Cat recommends the use of Cat oils as detailed in this article.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.
