How to Use This Spec

1

Drain old oil completely. Reinstall drain plug, torque to 25 ft-lb.

2

Install new oil filter (OEM: 68099474AA). Pre-lubricate the gasket with clean oil.

3

Add about 5.5 quarts of 5W-20 full synthetic oil first, then top off gradually.

4

Warm the engine, wait a few minutes, then verify oil level using the dipstick or in-vehicle oil level display if equipped. Reset the oil life monitor if equipped.

Fill gradually

Start around 5.5 quarts, then top off to the proper level after the engine circulates oil.

Match oil label

Use 5W-20 full synthetic and check any manual-listed approval before buying.

Record the service

Note mileage, oil grade, filter part, and date so the next maintenance interval is easier to verify.
