Engine Oil
Checking & Adding Oil
1. Run the engine at idle for 3 minutes, then shut
it off.
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 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.
• If the oil is below or near the lower level
mark, add the recommended oil until it
reaches the upper level mark. (Do not
overfill)
