and remove the cap.
• To install, reverse this procedure.

Engine Oil and Filter
Recommendations'
• Use only SE engine oil.
• Change oil each 6 months or
7,500 miles, whichever occurs
first,
except under the following
conditions:
*
-driving in dusty conditions
-trailer pulling
-extensive idling
-short-trip operation at
freez
ing temperatures (engine not
thoroughly warmed-up) .
*Under these conditions, change oil
each 3 months
or 3,000 miles,
whichever occurs first.
• Operation in dust storms may
require an immediate oil change.
• Replace the oil filter at the first
oil change, and every second oil
change thereafter. AC oil filters
5-2
provide excellent engine pro
tection.
See your Chevrolet dealer for
ad
vice on the frequency of oil and
filter changes under unusual driving
conditions.
The above recommendations
ap
ply to the first change as well as
subsequent oil changes. The oil
change interval for your Chevrolet
engine
is based on the use of SE
oils and quality oil filters.
Oil
change intervals longer than those
listed above will seriously reduce
engine life and may affect
Chevro
let obligation under the provisions
of the
New Vehicle Warranty.
NOTE: Non-detergent and other
low quality oils are specifically not
recommended.
Only the use of SE
engine oils and proper oil and filter
change intervals assure you of
con
tinued proper lubrication of your
Chevrolet engine.
