Oil capacity (guideline): Non-turbo models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
Turbo models: 4.8 US qt (4.5 liters, 4.0 Imp qt)
The oil quantity indicated above is only guideline.
The necessary quantity of oil depends on the quan- tity of oil that has been drained. The quantity of
drained oil differs slightly depending on the temper-
ature of the oil and the time the oil is left flowing out.
After refilling the engine with oil, therefore, you must
