Engine Oil
Note:
Note:
Cat DEO (Diesel Engine Oil)
True high performance oil is produced with a combination of the following factors: industry standard tests, proprietary tests, field tests and prior experience with similar formulations. The design and the development of Caterpillar lubricants that are both high performance and high quality are based on these factors.
Note:
Commercial Engine Oils
These Engine Crankcase Fluid Recommendations are for all Current and Noncurrent Caterpillar On-highway Truck Engines.
NOTICE
In selecting oil for any engine application, both the oil viscosity and oil performance classification/specification as specified by the engine manufacturer must be defined and satisfied. Using only one of these parameters will not sufficiently define oil for an engine application.

Note: CH-4 oils and CI-4 oils that have not met the requirements of Caterpillar's ECF-1 Specification may cause reduced engine life.
NOTICE
Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
Total Base Number (TBN) and Fuel Sulfur Levels for Direct Injection (DI) Diesel Engines
Note:
NOTICE
Operating Direct Injection (DI) diesel engines with fuel sulfur levels over 1.0 percent may require shortened oil change intervals in order to help maintain adequate wear protection.
Lubricant Viscosity Recommendations for Direct Injection (DI) Diesel Engines
Note:
NOTICE
Shortened engine service life could result if second choice oils are used.

Coolant Recommendations
NOTICE
Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" specification. This type of coolant/antifreeze is made for light duty automotive applications.
Use only the coolant/antifreeze that is recommended.
Note:
Note:
NOTICE
All Caterpillar diesel engines equipped with air-to-air aftercooling (ATAAC) require a minimum of 30 percent glycol to prevent water pump cavitation.
Note:
Distilled water or deionized water is recommended for use in engine cooling systems. DO NOT use the following types of water in cooling systems: hard water, softened water that has been conditioned with salt, and sea water. Damage to the cooling system may result.

Starting Recommendations
Batteries
If equipped with an air inlet heater (AIH) for cold weather starting, do not use types of starting aids such as ether. Such use could result in an explosion and injury.
NOTICE
When starting the engine with ether, follow these starting procedure instructions carefully.
Use ether sparingly and spray it ONLY WHILE CRANKING THE ENGINE. Excessive ether use can cause piston and ring damage. Ether should be used only for cold weather starting.
