Section 5.2
Lubricating Oil (Diesel)

The selection of the proper lubricating oil is important for achieving the long and trouble-free service Detroit Diesel Series 60 engines are designed to provide. Only oils displaying the American Petroleum Institute (API) Symbol shown below are recommended. This symbol assures that the lubricant meets the minimum performance levels necessary for proper engine performance and durability.‪

Section 5.2.1
Lubricant Requirement

Lubricants meeting these criteria have provided maximum engine life when used in conjunction with recommended oil drain and filter maintenance schedules. For the API symbol for this, see Figure "API Symbol" .‪

Figure 1. API Symbol

Lubricants meeting these criteria have provided maximum engine life when used in conjunction with specified oil drain and filter maintenance schedules. Only oils licensed by API may be used in Detroit Diesel engines. Lubricants meeting API Service category CH-4 are intended for use primarily with low (0.05%) sulfur fuel and may be used in all Detroit Diesel Series 60 engines. ‪

API CG-4 and CF-4 oils may be used when CH-4 oils are not available; however, their use may require a reduction in oil drain interval depending upon the application and the fuel sulfur level.‪

At ambient temperatures below -20°C (-4°F) when sufficient starter speed cannot be achieved with SAE 15W-40 oils, the use of 5W-XX and 10W-XX oils, where XX is 30 or 40, may be used to improve startability provided they are API CH-4 and have demonstrated field performance in DDC engines. These oils must possess a HT/HS of 3.7 minimum. ‪

When the use of high sulfur fuel (greater than 0.5% mass sulfur) is unavoidable, higher alkalinity lubricants are recommended. High sulfur fuels require modification to oil drain intervals. For further information refer to section, "The Use of High Sulfur Fuels." ‪

Section 5.2.2
Oil Change Interval

The length of time an engine may operate before changing oil depends on the lubricant and fuel used, engine oil consumption, and operating cycle. The maximum interval the engine may operate before changing oil is listed in Table "Maximum Oil Drain Intervals" . Oil analysis may be used to determine whether this interval should be shorter, but should not be used to lengthen the interval.‪

Table 1. Maximum Oil Drain Intervals

Note: Change both full-flow filters when lube oil is changed.
*Whichever comes first.
†Drain intervals shown apply to pre-1998 model year engines. 1998 and newer engines may require a modification to these intervals based on used oil analysis. Refer to publication "Lubricating Oil, Fuel, and Filters", form 7SE270 (9901), available from authorized Detroit Diesel distributors.

Note: The use of fuels with sulfur content above 0.5% will require a shorter drain interval, and/or the use of a higher TBN oil. Refer to DDC Publication 7SE270, Lubricating Oil, Fuel, and Filter Recommendations, for details.

Extending Oil Drain Intervals: Some oil companies may promote engine lubricants with a claimed useful life that would allow customers following certain maintenance and operating parameters to elect to extend oil drain intervals beyond the recommended periods. The ability of such lubricants to maintain their protective qualities over a longer period and the acceptability of maintenance and operating parameters must be established by the oil company and the customer. Claims for engine failure attributable to the inadequacy of the lubricant are not covered under the terms of the engine's limited warranty.‪

Section 5.2.3
Statement of Policy on Supplemental Fuel and Lubricant Additives

The Series 60 engine will operate satisfactorily on the commercial fuels and lubricants of good quality regularly provided by the petroleum industry through retail outlets. ‪

Supplementary additives include all products marketed as fuel conditioner, smoke suppressants, masking agents, deodorants, tune-up compounds, top oils, break-in oils, graphitizers, and friction-reducing compounds. The regular and continued use of supplementary additives in fuels and lubricants is not recommended.‪

Note: DDC is not responsible for the cost of maintenance or repairs due to lack of required maintenance services performed or the failure to use fuel, oil, lubricants and coolant meeting DDC-recommended specifications. Performance of required maintenance and use of proper fuel, oil, lubricants and coolant are the responsibility of the owner. See the OEM's guidelines for details.

Section 5.2.4
Filter Selection and Change Intervals for Series 60 Engine

For oil and fuel filter part number information, refer to the Series 60 Operators Guide (6SE484) and Lubricating Oil, Fuel and Filters Technicians Guide (7SE270).‪

The change intervals for oil and fuel filters are listed in Table "Maximum Lubricating Oil and Fuel Filter Replacement Intervals" .‪

Table 2. Maximum Lubricating Oil and Fuel Filter Replacement Intervals

* Whichever comes first.
†Drain intervals shown apply to pre-1998 model year engines. 1998 and newer engines may require a modification to these intervals based on used oil analysis. Refer to publication "Lubricating Oil, Fuel, and Filters", form 7SE270 (9901), available from authorized Detroit Diesel distributors.

Note: The spin-on fuel filter replacement intervals listed in Table "Maximum Oil Drain Intervals" do not apply to Fuel Pro filter elements, which must be replaced when the fuel level in the see-through cover reaches the top of the element or after one year of service, whichever comes first.

Section 5.2.5
Used Lubricating Oil Analysis Guidelines

These values indicate the need for an immediate oil change, but do not necessarily indicate internal engine problems requiring engine teardown. Characteristics relating to lubricating oil dilution should trigger corrective action to identify and find the source(s) of leaks, if the values listed in Table "Used Lubricating Oil Analysis Guidelines for Immediate Oil Change" are realized. Contact your DDC distributor or dealer regarding oil analysis services.‪
