2. Stop the engine.

3. Remove the oil filler cap (on rocker cover) and the drain plug (on the oil pan). Drain the engine oil.
4. Re-install and tighten the drain plug to the specified torque.
Tightening torque:
Drain plug: 35 - 45 Nm (350 - 450 kg.cm, 25 - 33 ft. lbs.)
5. Fill the crankcase with fresh engine oil through the oil filler cap opening.
Capacity:
Dry fill: 4.3 lit (3.91 U.S. qts., 3.25 Imp. qts.)
Drain and refill:
Without oil filter: 3.7 lit (3.91 U.S. qts., 3.25 Imp. qts.)
With oil filter: 4.0 lit (4.23 U.S. qts., 3.51 Imp. qts.)
CAUTION: Do not overfill the crankcase. This will cause oil aeration and loss of oil pressure.
6. Install the oil filler cap.
7. Start and run the engine.
8. Stop the engine and then check the oil level. Add oil if necessary.
