Detroit™ currently will allow DFS 93K218 (API CJ-4) oils with appropriate drain
intervals (see maintenance intervals Refer to section "EPA07/EPA10/GHG14/
GHG17 Preventive Maintenance Tables - 93K218(CJ-4)" ).
Cold Weather Starting
NOTICE: Monograde oils should not be used in the engine, regardless of
API service classification. Monograde oils gel at lower ambient
temperatures, reducing lubricant flow, and do not provide adequate lubricity
at higher engine operating temperatures resulting in severe engine
damage.
For picking a lubricant for low temperature applications, Refer to section "How to
Select Lubricating Oil" and Refer to section "How to Select Lubricating Oil
(EPA07)" or DDC-SVC-BRO-0001.
Use of Synthetic Oils
NOTE: Synthetic oil does not permit extension of recommended oil drain
intervals.
Synthetic oils may be used in Detroit™ engines provided they are approved by a
DFS. The use of synthetic oils does not necessarily ensure the extension of the
recommended oil drain intervals beyond the limits.
Use of Supplemental Additives
Lubricants meeting the Detroit™ specifications outlined in this publication already
contain a balanced additive treatment. Supplemental additives are generally not
necessary and can even be harmful. These additives may be marketed as either oil
treatments or engine treatments and are discouraged from use in Detroit™ engines.
