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 on page 10 15.
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 vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview on
page 10 10 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 propulsion
system and allow several
minutes for the oil to drain back
into the oil pan. Checking the
oil level too soon after engine
shut off will not provide an
accurate oil level reading.
2. Pull 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
1 L (1 qt) of the recommended
oil and then recheck the level.
See Selecting the Right Engine Oil
in this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12 2.
