This section covers Detroit Diesel's

by the operator.
NOTICE:
The manufacturer's warranty
applicable to MBE 900 engines
provides in part that the provisions
of such warranty shall not apply
to any engine unit that has been
subject to misuse, negligence or
accident. Accordingly, malfunctions
attributable to neglect or failure to
follow the manufacturer's fuel or
lubricating recommendations may
not be within the coverage of the
warranty.
How to Select Lubricating
Oil
The selection of the proper lubricating
oil is important to achieve the long
and trouble-free service which Detroit
Diesel engines are designed to
provide. The proper lubricating oil for
model year 2007 MBE 900 engines
is selected based on SAE viscosity
grade and API (American Petroleum
Institute) service designation.
Only oils licensed to display the API
symbol should be used. See Figure 31.

Lubricant Requirements

API CJ-4 oils must be used in

and later build, exhaust emission
regulations.

Cold Weather Starting

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 oils
and 10W-XX oils (XX =30 or 40) is
allowed to improve starting.
