In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolinesare specially designed
to reduce vehicle emissions. General
Motors recommends that
you use
reformulated gasoline. By doing so, you
can help clean the air, especially in
those parts of the country that have
high ozone levels.
You should.aslc your service station
operators
if their gasolines contain
detergents and oxygenates, and
if they
have been reformulated to reduce
vehicle
emissions.
Fuels in Foreign Countries
If you plan on drivingh 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 tankful, your emission
controls won't
work well or at all. With
continuous use,
spa& 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 ofthat 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
cuspany that does business in the
countqrwhere 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) .

Leaving your hood open and your
underhood lights on can drain your
battery.
If you need to keep the hood
open for an extended period
of time,
remove the Underhood Lights Fuse.
This 1O-amp fuse is located under the
hood on the left-hand marker light
assembly. See the
Index under Fuses &
Circuit Breakers.
Engine Oil
It's a good.idea to check pur engine oil
level every time you get fuel. In order to
get
an accurate reading, the vehicle
must be on level
ground.
If you have the LTl engine, the best
time
to check your engine oil is when
the
engine is warn. If the engine is
mnning, the engine oil won't drain back
into the pan.
Turn off the engine and
give the oil a few minutes to drain back
into the-oil
pan. If you don't, the oil
dipstick might not show the actual
level. If
you have a ZR-1, the best time to
chegk your engine oil is when
the
engine
is cold. If you run the engine, the
engine oil
won't drain back into the pan
fast enough.
Give the oil two hours to
drain
back into the oil pan. If you don't,
the oil dipstick might not
show the
actual level.
