Commercial Oils
The performance of commercial diesel engine oils is based on American Petroleum Institute (API) classifications. These API classifications are developed in order to provide commercial lubricants for a broad range of diesel engines that operate at various conditions.If Caterpillar multigrade Diesel Engine Oil is not used, only use commercial oils that meet the following classifications:
EMA LRG-1 multigrade oil (preferred oil)
API CH-4 multigrade oil (preferred oil)
API CG-4 multigrade oil (preferred oil)In order to make the proper choice of a commercial oil, refer to the following explanations:EMA LRG-1 - The Engine Manufacturers Association (EMA) has developed lubricant recommendations as an alternative to the API oil classification system. LRG-1 is a Recommended Guideline that defines a level of oil performance for these types of diesel engines: high speed, four stroke cycle, heavy-duty and light duty. LRG-1 oils may be used in Caterpillar engines when the following oils are recommended: API CH-4 and API CG-4. LRG-1 oils are intended to provide superior performance in comparison to API CG-4.LRG-1 oils will meet the needs of high performance Caterpillar diesel engines that are operating in many applications. The tests and the test limits that are used to define LRG-1 are similar to the new API CH-4 classification. Therefore, these oils will also meet the requirements of the low emissions diesel engines. LRG-1 oils are designed to control the harmful effects of soot with improved wear resistance and improved resistance to plugging
