This publication specifies the type of fuels, lubricants, filters and related maintenance intervals required for the diesel-fueled engines manufactured and marketed by Detroit Diesel Corporation, except the Series 2000® and Series 4000™ engines.

For Series 2000 or Series 4000 engine lubricating oil, fuel and coolant requirements, refer to publication, MTU Fluid and Lube Specifications, A001061/26E, available from authorized DETROIT DIESEL® distributors.

For information on fuels, lubricants and filters required for DDC® engines using alternate fuels (other than diesel fuel) and other engine products not covered in this publication, refer to the specific publications for those engines.

Selection of the proper quality of fuel, lubricating oil and filters in conjunction with required oil and filter maintenance is required to achieve the long and trouble-free service which Detroit Diesel engines are designed to provide. Operation with improper fuels, lubricants and filters can degrade engine performance and may void the manufacturer’s warranty.

Lubricating Oil Requirements

Labeling terminology for today’s oil is insufficient as a method of lubricant selection. The proper lubricating oil for Detroit Diesel engines is based on SAE (Society of Automotive Engineers) Viscosity Grade and API (American Petroleum Institute) Service Designation, displayed on the API symbol. For most Detroit Diesel engines, the proper lubricant must possess additional requirements that follow.
