Ducati 999 2003 Manuel D'utilisation Et Entretien page 179

Checking engine oil level
Engine oil level can be checked through the sight glass
(1) provided on the clutch cover.
When checking oil level, the motorcycle should be
upright and the engine cold.
Allow a few minutes for oil to settle to a steady level
after stopping the engine.
Oil level should be between the marks near the sight
glass. Top up oil level with SHELL Advance Ultra 4, if low.
Undo the filler plug (2) and top up to correct level.
E
Refit the plug.
Important
Engine oil and oil filters must be changed by a
Ducati Dealer or Authorized Workshop at regular
intervals, as specified in the routine maintenance chart
(see Warranty Card).
