1 Engine oil
The performance, service lifetime, and startability of
the engine depend to a large degree on the quality
of the engine oil. Always use oil of the correct grade
and viscosity.
The proper engine oil viscosity numbers for various
atmospheric temperature ranges are shown in the
diagram.
Change the engine oil for the first time at the initial
maintenance period of 2500 miles (4000 km).
CAUTION
To prevent engine damage, replace the engine
oil more often if the engine is frequently used at
high speed or under heavy load.
Recommended lubricant:
Engine oil
API classification CD, CD/SF, CE, CE/SF, CF-4 or
JASO classification DH-1
SAE40, 30, 20W-20, 10W-30, 15W-40
CAUTION
Engine oil with an API classification of CC will
damage the engine. Be sure to use engine oil
with a classification of CD or higher.
Quantity required (approximate):
The engine oil level can be checked by using either
the dipstick or the low oil level switch on the instru-
ment panel. The low oil level switch is for a quick
check. Use the dipstick for a more accurate check.
NOTE:
To check the engine oil level, park the vehicle on a
level surface and shut down the engine. If the vehi-
cle is tilted, the correct engine oil level cannot be
determined. While the engine is running, oil circu-
lates out of the oil pan and drips slowly back down
after the engine is shut down. For an accurate level
check, let the engine stand at least 30 minutes after
shutdown.
