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.”
.
Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and “When to Add
Engine Oil.”
.
Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑11.
.
Always dispose of engine oil
properly. See “What to Do With
Used Oil.”
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
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 your oil level too soon
after engine shut off will not
provide an accurate oil level
reading.
2. Pull out the dipstick and clean
it with a 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
If the oil is below the cross-hatched
area at the tip of the dipstick, add
one quart/liter of the recommended
oil and then recheck the level. See
“Selecting the Right Engine Oil” for
an explanation of what kind of oil
to use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 12‑2.
Notice: Do not add too much oil.
Oil levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that
you have an oil level above the
operating range, i.e. the engine
has so much oil that the oil level
