oil additives CADILLAC ELDORADO 1998 10.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine As shown in the chart, SAE 1OW-30 is best for your
vehicle. However,
you can use SAE 5W-30 if it’s going
to be colder than
60°F (16°C) before your next oil
change. When it’s very cold, you should use
SAE
5W-30. These numbers on an oil container show its
viscosity, or thickness.
Do not use other viscosity oils,
such as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst”
symbol. Failure to use the
recommended oil can result in engine damage not
covered
by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls
below
-20°F (-29”C), consider using either an
SAE 5W-30 synthetic oil or an SAE OW-30 oil. Both
will provide easier cold starting and better protection
for your engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if
you think something should be added.
When to Change Engine Oil
Your vehicle has an Oil Life Indicator. This feature
will let
you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t dete.ct dust in the
oil. So, if you
drive in
a dusty area, be sure to change your oil
every
3,000 miles (5 000 krn) or sooner. Remember
to reset the Oil Life Indicator when the oil has been
changed. For more information, see “Oil Life Indicator”
in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL” coolant which
won’t damage aluminum parts.
If you use this mixture.
you don’t need
to add anything else.
A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water
or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a
50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your
warranty.
Too much water in the mixture can
freeze and crack the engine, radiator, heater
core and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
~~~~~
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
