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.
.
Change the engine oil at the
appropriate time. See
“
Engine
Oil Life System
”
in the owner
manual.
.
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, at normal operating
temperature, and the vehicle must
be on level ground. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview on
page 10-3
for the location of the
engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. Turn off the engine and allow at
least five minutes for the oil to
drain back into the oil pan. With
a cool engine, allow 30 minutes.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
