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 0 230.
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 loop. See
Engine Compartment Overview
0 223 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.
Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
