NOTE: If this cap requires a re-
placement, only · a cap with these
same features should be used. Fail-
ure to use the correct cap can re-
sult in a serious malfunction of the
system. Correct replacement caps
may
be
obtained from your Au-
thorized Chevrolet Dealer.
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.
