Energy Conserving II
Oils with these words on the container will help you save fuel.
The doughnut-shaped logo (symbol) is used on most oil contain\
ers to
help you select the correct oil.
You should look for this on the oil container, and use
only those oils
that display the logo.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the \
requirements for your vehicle.
Engine Oil Additives: Don’t add anything to your oil. Your General
Motors dealer is ready to advise
if you think something should be added.
When to Change Engine Oil: See if any one of these is true for you:
Most trips are less than
4 miles (6 km).
It’s below freezing outside and most trips are less than 10 miles
(16 km).
The engine is at
low speed most of the time (as in door-to-door delivery,
or in stop-and-go traffic).
You
tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your vehicle, then you need to change
your
oil and filter every 3,000 miles (5000 km) or 3 months-whichever
comes first.
If none of them is true, change the oil every 7,500 miles (12 500 km) or
12 months-whichever comes first. Change the filter at the first oil
change and at every other oil change after that.
Engine Block Heater: An engine block heater can be a big help if you have
to park outside in very cold weather,
0°F (-18°C) or colder. If your vehicle
has this option, see “Engine Block Heater” in the Index.

Hood Latches and Hood Hinge
The Maintenance Schedule will tell you how often to lubricate the hood latch
and hood hinge assembly. See “Recommended Fluids and Lubricants”\
in the
Index for the proper lubricant
to use.
Propeller Shaft Slip Splines/Universal Joints
The Maintenance Schedule will tell you how often the slip splines must be
lubricated. See “Recommended Fluids and Lubricants” in the \
Index for the
proper lubricant
to use.
Constant Velocity Joints (All- Wheel Drive Only)
The Maintenance Schedule will tell you how often to lubricate the the
constant velocity joints. See “Recommended Fluids and Lubrican\
ts” in the
Index for the proper lubricant
to use.
Sliding Door Tracks
Your vehicle’s sliding door has three tracks which need lubricatio\
n.
For the upper and lower tracks, open the door, wipe the track\
clean and then
lubricate with Lubriplate@ White Grease.
For the outside middle track, close the door after you finish \
the upper and
lower tracks. Then, wipe the track clean and lubricate with Lu\
briplateB White
Grease.
Body
Normal use of your vehicle will cause metal-to-metal wear at some points \
on
the cab and body
if they are not lubricated.
tor exposed surfaces, such as door checks, door lock bolts, lock s\
triker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless \
oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
Door weatherstrips and rubber hood bumpers should be lightly coated with
a
rubber lubricant.
Never use
too much of any lubricant and be sure to wipe up any extra
lubricant when you are finished.
Some parts that need lubricating are hard
to get at. Window regulators and
controls are inside the doors. You can get to these by removing the trim
panels.
