INSPECTION AND MAINTENANCE
Oil Identification Logo (for United States
and Canada Only)
A logo (symbol) is used on most oil containers to
help you select the oil you should use. The top
portion of the logo shows the oil quality by API
designations such as CJ-4 or others. The center
portion of the logo shows the SAE viscosity
grade, such as SAE 10W-40. You should look
for this logo on the oil container, and use only oil
containing the logo.

Inspecting the Engine Oil

NOTE
• Perform inspection on a level surface
before starting the engine.
• Accurate oil level cannot be measured
when the engine is running.
• When the engine has been running, wait
for 10 - 20 minutes after stopping the
engine and then measure the oil level.
1. Pull out the oil dipstick and wipe off the
attached oil.
2. Reinsert the oil dipstick fully and then gently
pull it out. When the oil surface is between
the "FULL" and "ADD", the oil level is
appropriate.
At this time, also check for the degree of oil
contamination and stickiness.
3. When the oil level is insufficient, add the oil
up to the "FULL" position.
4. Reinstall the oil dipstick into position after
checking the oil level.
