Engine Oil

To ensure proper engine performance and
long life, careful attention must be paid to
engine oil. Following these simple, but
important steps will help protect your
investment:
Use engine oil approved to the proper
specification and of the proper viscosity
grade. See Selecting the Right Engine
Oil in this section.
Check the engine oil level regularly and
maintain the proper oil level. See
Checking Engine Oil and When to Add
Engine Oil in this section.
Change the engine oil at the appropriate
time. See Engine Oil Life System 0 262.
Always dispose of engine oil properly. See
What to Do with Used Oil in this
section.
Checking Engine Oil
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. The engine oil dipstick handle is a loop.
See Engine Compartment Overview 0 257 for
the location.
Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
If a low oil Driver Information Centre (DIC)
message displays, check the oil level.
Follow these guidelines:
To get an accurate reading, park the
vehicle on level ground. Check the engine
oil level after the engine has been off for
at least two hours. Checking the engine
oil level on steep gradients or too soon
after engine shutoff can result in incorrect
readings. Accuracy improves when
checking a cold engine prior to starting.
Remove the dipstick and check the level.
If unable to wait two hours, the engine
must be off for at least 15 minutes if the
engine is warm, or at least 30 minutes if
the engine is not warm. Pull out the
dipstick, wipe it with a clean paper towel
or cloth, then push it back in all the way.
Remove it again, keeping the tip down,
and check the level.
When to Add Engine Oil
LSY 2.0L L4 Turbo Engine
LSQ 2.0L L4 Turbo Diesel Engine
If the oil is below the cross-hatched area at
the tip of the dipstick and the engine has
been off for at least 15 minutes, add 1 L (1
qt) of the recommended oil and then
recheck the level. See Selecting the Right
Engine Oil later in this section for an
explanation of what kind of oil to use. For
engine oil crankcase capacity, see Capacities
and Specifications 0 335.
