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.
At ambient temperatures below -10° C (14° F), SAE 5W-30, 5W-40, or 10W-40
oils may be used, provided they are API CI-4 PLUS and have demonstrated field
performance in Detroit™ engines. These oils must possess a High Temperature /
High Shear Viscosity of 3.7 cP minimum.
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
POWER GUARD® Oil Specification (PGOS) 93K214. The use of synthetic oils
does not necessarily ensure the extension of the recommended oil drain intervals
beyond the limits. Synthetic oils offer improved low-temperature flow properties,
high-temperature oxidation resistance, and improved fuel mileage. However, they
are generally more costly than non-synthetic oils.
Product information about synthetic oils should be reviewed carefully. Performance
additive systems often respond differently in synthetic oils.
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.
Engine damage resulting from the use of such materials is not covered by your
Detroit™ warranty. Detroit™ will not provide statements beyond this publication
relative to their use.
When to Change Oil
Refer to DDC-SVC-BRO-0001 for more information.
The length of time an engine may operate before an oil change depends upon the
lubricant and fuel used, engine oil consumption, and the operating cycle.
CAUTION: USED ENGINE OIL
To avoid injury to skin from contact with the contaminants in used
engine oil, wear protective gloves and apron.
