Engine Oil Life System - GMC 2010 Acadia Owner's Manual

What Kind of Engine Oil to Use
Look for three things:
GM6094M
Use only an oil that meets
GM Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use
other viscosity oils such as
SAE 20W-50.
American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container.
This symbol indicates that
the oil has been certified by
the American Petroleum
Institute (API).
Notice: Use only engine oil
identified as meeting GM
Standard GM6094M and showing
the American Petroleum Institute
Certified For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold,
where the temperature falls
below 20°F ( 29°C), use either
an SAE 5W-30 synthetic oil or an
SAE 0W-30 engine oil. Both provide
easier cold starting for the engine at
extremely low temperatures. Always
use an oil that meets the required
specification, GM6094M. See What
Kind of Engine Oil to Use for more
information.
Vehicle Care
Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
starburst symbol that meet GM
standards are all that is needed
for good performance and engine
protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.

Engine Oil Life System

When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
