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
--
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 (12 000 km) or 12 months
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 Oil Soon" light 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.
How to Reset the
O i l
Life Indicator
After the oil has been changed, display the "OIL LIFE LEFT" message
by pressing the INFORMATION button. Then press and hold the
RESET button until the display shows "100". This resets the oil life index.
The message will remain off until the next oil change is needed. The
percentage of oil life remaining may be checked at, any time by pressing
the INFORMATION button several times until the "OIL LIFE LEFT"
message appears. For more information on the Oil Life Index feature,
see
"Oil Life Index" in the Index.
Engine Coolant Heater (Engine Block Heater)
An
engine coolant heater can be a big help if you have to park outside in
very cold weather, 0" F (-18OC) or colder. If your vehicle has this option,
see "Engine Coolant Heater" in the Index.
