Step 4

We will now replace the oil filter. Looking forward from the sump, you will find a small panel to remove. This will reveal the filter.

Using the filter wrench, loosen and remove the oil filter. The filter will drip a large amount of oil, so ensure your oil pan is at the ready.

To help reduce oil starvation, half fill the new filter with fresh oil, and screw into position. Hand tighten.

Step 5

Lastly fill the engine with approximately 5.2L of 5w-30 fully synthetic oil. Continuously check the dipstick to ensure the oil is at the correct level.

Once filled, start and idle the engine for a few minutes. Turn the engine off and check for any leaks, and double check the dipstick as the level may have dropped slightly.
