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:
.
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’s
manual.
.
Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See

checking a cold engine prior to
starting. Remove the dipstick

engine must be off for at least
15 minutes if the engine is
warm, or at least 30 minutes if
