CHANGING ENGINE OIL
CAUTION: Be careful not to burn yourself, as the engine oil is hot
1. Run the engine until it reaches normal operating temperature.
2. Turn off the engine.
3. Remove the oil filler cap and the drain plug (on the oil pan). Drain the engine oil.
4. 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
Drain and refill
Without oil filter: 3.7 liter (3.91 U.S. quarts, 3.25 Imp. quarts)
With oil filter: 4.0 liter (4.23 U.S. quarts, 3.51 Imp. quarts)
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. Turn off the engine and then check the oil level. Add oil if necessary.
