• Oil is a major factor affecting the performance
and service life of the transmission and clutch.
Other viscosities shown in the following chart
may be used when the average temperature in
your riding area is within the indicated range.
JASO T 903 standard
The JASO T 903 standard is an index for engine
oils for 4-stroke motorcycle engines.

* Suggested 4-stroke engine oils are equal
performance to SJ oils that are not labeled as

the circular API service label.
• Your CRF does not need oil additives. Use the
recommended oil.
• Do not use oils with graphite or molybdenum
additives. They may adversely affect clutch
operation.
• Do not use API SH or higher 4-stroke engine
oils displaying a circular API “energy
conserving” or “resource conserving” service
label on the container. They may affect
lubrication and clutch performance.
NOT RECOMMENDED OK
Transmission Oil
Refer to Safety Precautions on page 25.
Using the proper oil, and regularly checking,
adding, and changing oil will help extend the
service life of the transmission and clutch. Even
the best oil wears out. Changing oil helps get rid
of dirt and deposits. Operating the engine with
old or dirty oil can damage your engine. Running
the engine with insufficient oil can cause serious
damage to the engine and transmission.
