If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not’ use leaded gasoline. If you use
even one tank full, your emission controls won’t work well \
or at all. With
continuous use, spark plugs can get fouled, the exhaust system \
can corrode,
and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor will
be damaged.
All of that means costly repairs that wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address
for advice. Just tell us where
you’re going and give your Vehicle Identification Number
(VIN).

Things that burn can get on hot engine parts and start a fire. These
include liquids like gasoline, oil, coolant, brake fluid, windsh\
ield
washer and other fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things that will burn onto a
hot engine.

Then lift the hood to relieve pressure on the hood prop. Remove the hood
prop from the slot in the hood and return the prop to its retainer. Then just
let the hood down and close
it firmly.
Engine Oil
It’s a good idea to check your engine oil every time you get fuel. In order to
get an accurate reading, the oil must be warm and the vehicle\
must be on level ground.

Turn off the engine and give the oil a few minutes to drain back down into
the oil pan.
If you don’t, the oil dipstick might not show the actual level\
.
To Check Engine Oil: Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it again, keeping the tip
lower.

When to Add Oil: If the oil is at or below the ADD line, then you’ll need to
add some oil. But you must use the right kind. This section \
explains what
kind
of oil to use. For crankcase capacity see ‘Capacities and Speci\
fications’’
in the Index.

What Kind of Oil to Use:
Look for three things:
SG
SG must be on the oil container, either by itself or combined with other
quality designations, such as
SG/CC, SG/CD, SF, SG, CC, etc. These
letters show American Petroleum Institute (API) levels of quality.
NOTICE I
you use oils that don’t have the SG dl
3maae not covered bv vour warrantv.

SAE 5W-30
As shown in this chart, SAE 5W-30 is best
for your vehicle. However,
you can use SAE IOW-30
if it’s going to be 0°F (-18°C) or above.
These numbers on an oil container show its viscosity,
or thickness. Do
not use other viscosity oils such as SAE 1OW-40 or SAE 2OW-50.

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.
