reduce varnish and sludge de-
posits resulting from some unusual
operational difficulty, a thoroughly
tested and approved concentrate-
"Engine
Oil Supplement"-is avail-
able at your Chevrolet dealer.
It
is suggested that, in the event of
an operational problem, you con-
sult your dealer for advice.
Engine Oil Change Interval
Change oil each 4
months.
If
more than 6,000 miles
are
driven
in
a
4-month period,
change
oil
each 6,000 miles.
In certain types of
service
in-
cluding:
• operation under dusty condi-
tions,
• trailer pulling,
• extensive idling, or
•
short
trip operation at freezing
temperatures
(engine
not thor-
oughly warmed up),
• commercial type use, such as
taxicab, limousine or patrol car
use.
the oil change interval should not
exceed 2 months, or 3,000 miles,
whichever occurs first. Operation
in dust storms may require an im-
mediate change of oil. See your
Chevrolet dealer for advice on the
frequency of oil and filter changes
under unusual driving conditions.
The above recommendations
apply to the first change as well as
subsequent oil changes. The oil
change interval for your Monte
Carlo engine is based on the use of
oils that meet the requirements
indicated in the section on "En-
gine Oil Recommendations". Oil
change intervals longer than those
listed above will result in serious
reduction in engine life and may
affect Chevrolet's obligation under
the provisions of the New Vehicle
Warranty.
A high quality MS oil meeting
58
General Motors Standard GM
6041-M was installed in your
engine at the factory. It is not
necessary to change this factory-
installed oil prior to the recom-
mended normal change period.
However, the oil level should be
checked more frequently during
the break-in period since some-
what higher oil consumption is
normal until the piston rings be-
come sealed.
Engine Oil Filter
Replacement
The engine oil filter should be
replaced at the first oil change and
every second oil change thereafter.
This recommendation is based on
the use of engine oils that meet the
requirements indicated in the sec-
tion on "Engine Oil Recommenda-
tions", and the use of a quality oil
filter. AC Oil Filters provide maxi-
mum engine protection.
