1997 CADILLAC DEVILLE oil additives

Downloaded from www.Manualslib.com manuals search engine To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol,
and reformulated gasolines may be available in your
area to help clean the air. General Motors recommends
that you use these gasolines
if they comply with the
specifications described earlier.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on
fuel. Costly repairs
caused by use of improper fuel 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.

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 OF ( 16 O 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.
I I
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 Cadillac dealer is
ready to advise if
you think something should be added.
When to Change Engine Oil
Your Cadillac 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 detect dust in the oil.
So, if you
drive
in a dusty area, be sure to change your oil
every 3,000 miles
(5 000 km) or sooner if the
CHANGE
ENGINE OIL message comes on.
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.
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
mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, 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 mix of clean
water and
DEX-COOL@ coolant.
I NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix 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.
