Checking The Engine Oil Level - Monster 659 Owner's Manual

Checking the engine oil level

Check the engine oil level through the sight glass (1) on the
clutch cover.
Check the oil level with the motorcycle upright and the
engine cold. Allow a few minutes for the oil level to stabilize
after stopping the engine.
Oil level should be between the marks near the sight glass.
If the level is low, top up with SHELL Advance 4T Ultra
engine oil.
Remove the oil filler cap (2) and top up until the oil reaches
the required level. Refit the plug.
Important
Engine oil and oil filters must be changed by a Ducati
Dealer or Authorised Service Centre at the intervals specified
in the scheduled maintenance table reported in the Warranty
Card.
