Figure 21 API Lubricant Symbol Lubricant Requirements Lubricant requirements are different for the EGR-equipped and non-EGR engines. EGR-Equipped Engines API CI-4 oils must be used in October 2002 and later–build Series 60 engines with cooled EGR (exhaust gas recirculation) devices. API Service Category CI-4 is intended for use with cooled EGR (exhaust gas recirculation) engines meeting 2002 and later exhaust emission regulations. How to Select Lubricating Oil The selection of the proper lubricating oil is important to achieve the long and trouble-free service which Detroit Diesel engines are designed to provide.
The proper lubricating oil for all Detroit Diesel engines is selected based on SAE viscosity grade and API (American Petroleum Institute) service designation. Only oils licensed to display the API symbol should be used. See Figure 21. Non-EGR Engines — API CI-4 or CH-4 oils are recommended for use in all non-EGR engines. Engines Built Prior to 1998 Lubricants meeting API Service All information subject to change without notice. 75 DDC-SVC-MAN-0039 Copyright © 2009 DETROIT DIESEL CORPORATION
