SECTION 1 - LUBRICANTS, LUBRICATION AND MAINTENANCE SCHEDULE

GENERAL INFORMATION

The recommended lubrication and maintenance services have been determined to provide maximum performance and protection of the vehicle under various types of operating conditions. The information in this group is intended to aid service personnel in selecting and using the correct lubricants and maintenance procedure.

No particular brand of lubricant is recommended, how­ ever lubricants manufactured by a reputable oil company should always be used. It is important that the specifica­ tions of the material used, meets the standards stated in this manual.

NOTE: Recommended lubricants are formulated with the optimum quantities of a carefully balanced combination of selected additives, for use in vehicles marketed by Chrysler. Consider­ able development work is involved M finally establish the most suitable lubricant to satisfy all requirements of a specific application. Thus any arbitrary addition of proprietary materials will disrupt the balance of additives already present in optimum quantities and may destroy the essential properties built into the approved lub­ ricants, resulting in failure of the mKhanical assembly. Furthermore, addition of proprietary materials is an unnecessary and expensive penalty to the vehicle operation maintenance costs.

Classification of Lubricants

Oils and lubricants are classified and graded according to standards recommended by the following organisations:

(I) SAE (Society of Automotive Engineers)

(2) API (American Petroleum .Institute)

(3) NLGI (National Lubricating Grease Institute) (4) MIL (U.S. Army Ordnance Specification)

(5) ASTM (American Society for Testing Materials)

Engine Oil

Three designations MIL, SAE and API are used to match engine oils to service requirements. Generally designations will be found on the oil container.

The SAE grade number indicates engine oil viscosity or fluidity. For example SAE 30 is a single viscosity oil. Most engine oils have multiple viscosity grades such as SAE lOW 30, with a low viscosity when cold. These multigrade oils have a more constant viscosity than single grade oils for the same temperature rise.

The API and! or MIL classification designates engine oils suitable for use under certain specified conditions.

Grease

Semi-solid lubricants, such as those specified fOl' uni­ versal joint, chassis, and similar applications should meet NLGI Multi-Purpose Grade 2 E.P. specifications except where otherwise stated.
