Engine Oil
JASO T 903 standard
The JASO T 903 standard is an index to choose

There are two classes: MA and MB.
Oil conforming to the standard has the following
classification on the oil container.
(1) code number of the sales company of the oil

2. Wait 3 minutes after shutting off the engine to
allow the oil to properly distribute itself in the
engine.
3. Support the CRF in an upright position on a
level surface.
4. Remove the engine oil filler cap/dipstick (1),
wipe it clean, and insert the engine oil filler
cap/dipstick without screwing it in. Remove
the engine oil filler cap/dipstick.
5. Check that the oil level is between the upper
(2) and lower (3) level marks on the engine oil
filler cap/dipstick.
• If the oil is at or near the upper level mark,
you do not have to add oil.
