Recomended Engine Oil

While that's an unqualified statement common to, and often repeated on
all the forums, it's not true unless qualified.

For Series 60 DD engines, multigrade is *required*. According to the
Detroit Diesel Publication 7SE270, Specification Guide to Lubricating
Oil, Fuel and Filters Requirements:
2.1.5 MONOGRADE OILS
Monograde oils, irrespective of API service category, should not be
used in on-road applications in any DDC 4-stroke engines or in
off-road applications in Series 40E, 50, 60, MBE 900 and
MBE 4000 engines.

For two stroke DD (92 series), monograde is recommended, but use of
multigrade is also allowed per the following portion of the guide on
page 2-4:
4. At ambient temperatures below freezing (32° F or 0° C), sufficient
starter cranking speed may not be achieved to start the engine with
SAE 40 grade oils. Where starting aids are not available or at very
cold temperatures (0° F to -25° F or -18° C to -32° C) even if
starting aids are available, the use of multigrade SAE 15W-40 or
monograde lubricant SAE 30 will improve startability. These lubricants
must possess a High Temperature – High Shear Rate Viscosity (measured
by ASTM D 4741 or equivalent) of 3.70 cP minimum. These oils must be
replaced with monograde SAE 40 lubricants as soon as ambient
conditions permit.
(This same info was also in the DD series 92 manuals in my blue box)

Further on the section on synthetics, the guide states (somewhat
ambiguously on the two strokes):
3.7 SYNTHETIC OILS
Synthetic oils should be used in Detroit Diesel engines provided they
are API licensed and meet the performance and chemical requirements
outlined in this publication. The oil should be a PGOS 93K214 approved
product for use in EGR equipped engines. For two-stroke cycle
engines, only synthetic oils which do not contain viscosity improver
additives may be used.

My personal interpretation on synthetics: Since most diesel
synthetics are multi weight (15W-40) and far exceed the typical
chemical and physical properties of a lubricant meeting Detroit Diesel
requirements in normal applications, as defined in their table 3-2, it
appears that multigrade synthetics meeting the spec are approved for
use in the two strokes.

FWIW.....
