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 6 20.
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 6 13 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.
