Refer to the “Lubricant Information” section in the latest revision of the Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for detailed information. This manual may be found on the Web at Safety.Cat.com.The following are the preferred oils for use in most Cat machine hydraulic systems:
Cat HYDO Advanced 10 SAE 10W
Cat HYDO Advanced 30 SAE 30W
Cat BIO HYDO AdvancedCat HYDO Advanced fluids have a 50% increase in the standard oil drain interval for machine hydraulic systems (3000 hours versus 2000 hours) over second and third choice oils when you follow the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual for your particular machine. 6000 hour oil drain intervals are possible when using S O S Services oil analysis. Consult your Cat dealer for details. When switching to Cat HYDO Advanced fluids, cross contamination with the previous oil should be kept to less than 10%.Second choice oils are listed below.

Grease
In order to use a non-Cat grease, the supplier must certify that the lubricant is compatible with Cat grease.Each pin joint should be flushed with the new grease. Ensure that all old grease is removed. Failure to meet this requirement may lead to failure of a pin joint.

Illustration 1 g03336462Diesel fuel must meet “Caterpillar Specification for Distillate Fuel” and the latest versions of "ASTM D975" or "EN 590" in order to ensure optimum engine performance. Refer to Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for the latest fuel information and for Cat fuel specification. This manual may be found on the Web at Safety.Cat.com.Failures that result from the use of improper fuels are not Caterpillar factory defects. Therefore the cost of repairs would not be covered by a Caterpillar warranty.Fuel Additives
Cat Diesel Fuel Conditioner and Cat Fuel System Cleaner are available for use when needed. These products are applicable to diesel and biodiesel fuels. Consult your Cat dealer for availability.Coolant Information
