Synthetic Oils - Detroit Diesel MBE 900 Operator's Manual

HOW-TO SECTION
NOTICE:
Monograde oils should not be used
in MBE 900 engines, regardless
of API service classification.
Monograde oils gel at lower ambient
temperatures, reducing lubricant
flow, and they do not provide
adequate lubricity at higher engine
operating temperatures. These
factors can result in severe engine
damage.
The oils must be API CJ-4
that have demonstrated field
performance in Detroit Diesel engines.
These oils must possess a High
Temperature/High Shear (HT/HS)
viscosity of 3.7 minimum. For further
information, refer to publication
Engine Requirements – Lubricating
Oil, Fuel and Filters, 7SE270,
available from authorized Detroit
Diesel distributors.
Select the SAE class (viscosity) on the
basis of the average air temperature
for the season see Figure 32

Synthetic Oils

Synthetic oils may be used in Detroit
Diesel engines, provided they are API
licensed and meet the performance
and chemical requirements of
non-synthetic oils outlined in this
publication. Synthetic oils offer
improved low-temperature flow
properties and high-temperature
oxidation resistance. 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.
NOTE:
The use of synthetic oils does not
permit extension of recommended oil
drain intervals.
