Engine Oil
Recommendations
Use only engine oil which meets
oil quality standard GM 6041-M.
High quality oils which are in
tended for service
MS and pass car
makers' tests are
of this quality.
The oil change interval (see para
graph entitled
"Engine Oil Change
Interval") and the new vehicle
warranty are based on the use of
oils that meet these requirements.
NOTE: Non-detergent and other
low quality oils are specifically not
recommended. The use of proper
engine oils and oil change intervals are
your best assurance of contin
ued reliability and performance
from your Camaro engine.
Checking Oil Level
The engine oil should be main
tained at proper level. The best
time to check it
is before operating
the engine or as
the last step in a
fuel stop. This will allow the oil ac
cumulation in the engine to drain
back in the crankcase .
To check
the evel, remove the oil gauge rod
(dip stick), wipe it clean and rein
sert it firmly for an accurate read
ing. The oil gauge rod
is marked
"FULL" and "ADD." The oil level
should be maintained in the safety
margin, neither going above the
"FULL" line nor below the "ADD"
line. Reseat the gauge firmly after
taking the reading.
NOTE: The oil gauge rod is also
marked
"Use GM 6041-M Quality
MS Oil" as a reminder to use only
52
high quality oils as prescribed
under "Engine Oil Recommenda
tions."
Supplemental Engine Oil
Additives
The regular use of supplemental
additives
is specifically not recom
mended and will increase operat
ing costs. However, in cases of spe
cific problems which may arise
under certain conditions, additive
supplements are available that can
effectively and economically solve
these problems without causing
other difficulties.
For example, if
higher detergency
is required to re
duce varnish and sludge deposits
resulting from some unusual opera
tional difficulty, a thoroughly tested
and approved concentrate -
"En
gine Oil Supplement"-is available
at your Chevrolet dealer.
It is sug
gested that, in the event of
an oper
ational problem, you consult your
dealer for advice.

Checking the coolant level at
each engine oil change. Level
should be
3" below bottom of filler
neck when cold.
Coolant Recommendations
The inhibited year-around cool
ant, used to
fill the cooling system
at the factory,
is a high quality so
lution that meets General Motors
Specifications 1899-M. This fac
tory-fill coolant solution
is formu
lated to withstand two full calendar
years of normal operation without
draining, provided the same con
centration of coolant
is added if the
system needs additional fluid be
tween drain periods. The original
factory-fill coolant provides freez
ing protection to
-20°F (-32°F
in Canada).
Every two years, the cooling sys
tem should be serviced as follows:
1. Drain coolant, when hot,
through the radiator drain valve.
2. Close valve and add sufficient
plain· water to
fill system.
3. Run engine until normal operat
ing temperature
is reached.
4. Drain and refill the system as
described in steps 1, 2, and 3 a
sufficient number of times until
the drained liquid
is colorless.
5. Allow system to drain com
pletely and then close radiator
drain valve tightly.
6.
Add the necessary amount of
high quality inhibited glycol
base coolant meeting GM
Speci
fication 1899-M to provide the
required freezing and corrosion
protection
(at least to O°F.)
7. Run engine until normal oper
ating temperature
is reached.
8. Check and adjust level of cool
ant after system has cooled
suffi
ciently to remove radiator cap.

NOTE: Addition of supplemental
additives and other available ma
terials which have not been specifi
cally approved by GM are not nor
mally required in your car. Use of
these materials will result in un
warranted operating expense.
It is the owner's responsibility to
keep the freeze protection at a level
commensurate with the tempera
tures which may occur in the area
in which the vehicle will be oper
ated. Regardless of whether freez
ing temperatures are
or are not ex
pected, cooling system protection
should be maintained at least to
OaF to provide adequate corrosion
protection. When coolant addi
tions are required because of cool
ant loss or to provide additional
protection against freezing at tem
peratures lower than
-20°F,
(-32°F in Canada), a sufficient
amount of an ethylene glycol base
