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:
Always 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.
Vehicle Care
Change the engine oil at the
.
appropriate time. See Engine Oil
Life System on page 10 13.
Always dispose of engine oil
.
properly. See "What to Do with
Used Oil" in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the oil
must be warm and the vehicle must
be on level ground. The engine oil
dipstick handle is a yellow loop. See
Engine Compartment Overview on
page 10 6 for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
